DefaultGroovyMethods (groovy 3.0.21 API)

org.codehaus.groovy.runtime.DefaultGroovyMethods

```
public class DefaultGroovyMethods
extends DefaultGroovyMethodsSupport
```
This class defines new groovy methods which appear on normal JDK classes inside the Groovy environment. Static methods are used with the first parameter being the destination class, i.e. public static String reverse(String self) provides a reverse() method for String.
NOTE: While this class contains many 'public' static methods, it is primarily regarded as an internal class (its internal package name suggests this also). We value backwards compatibility of these methods when used within Groovy but value less backwards compatibility at the Java method call level. I.e. future versions of Groovy may remove or move a method call in this file but would normally aim to keep the method available from within Groovy.

 - <T> public static boolean addAll(Collection<T> self, T[] items)
 
 Modifies the collection by adding all the elements in the specified array to the collection. The behavior of this operation is undefined if the specified array is modified while the operation is in progress. See also plus or the '+' operator if wanting to produce a new collection containing additional items but while leaving the original collection unchanged.
 Parameters:
 self - a Collection to be modified
 items - array containing elements to be added to this collection
 Returns:
 true if this collection changed as a result of the call

 - <T> public static boolean addAll(List<T> self, int index, T[] items)
 
 Modifies this list by inserting all the elements in the specified array into the list at the specified position. Shifts the element currently at that position (if any) and any subsequent elements to the right (increases their indices). The new elements will appear in this list in the order that they occur in the array. The behavior of this operation is undefined if the specified array is modified while the operation is in progress. See also plus for similar functionality with copy semantics, i.e. which produces a new list after adding the additional items at the specified position but leaves the original list unchanged.
 Parameters:
 self - a list to be modified
 items - array containing elements to be added to this collection
 index - index at which to insert the first element from the specified array

 assert false : 'should never get here'
 break
 }
 
```
 If the switch value is a class, isCase will return true if the switch value is assignable from the given class (case value), i.e. the case class is the same as, or a superclass, or a super-interface of the switch class, for example:
```
 switch (ArrayList) {

 Selects an entry in the map having the maximum calculated value as determined by the supplied closure. If more than one entry has the maximum value, an arbitrary choice is made between the entries having the maximum value.
 If the closure has two parameters it is used like a traditional Comparator. I.e. it should compare its two parameters for order, returning a negative integer, zero, or a positive integer when the first parameter is less than, equal to, or greater than the second respectively. Otherwise, the Closure is assumed to take a single parameter and return a Comparable (typically an Integer) which is then used for further comparison. An example:
```
 def zoo = [monkeys:6, lions:5, tigers:7]
 def mostCommonEntry = zoo.max{ it.value }
 assert mostCommonEntry.value == 7
 def leastCommonEntry = zoo.max{ a, b -> b.value <=> a.value } // double negative!

 def nums = [ 1, 2, 3 ] as SortedSet
 assert nums.takeWhile{ it < 1 } == [] as SortedSet
 assert nums.takeWhile{ it < 2 } == [ 1 ] as SortedSet
 assert nums.takeWhile{ it < 4 } == [ 1, 2, 3 ] as SortedSet
 
```
 Parameters:
 self - the original SortedSet
 condition - the closure that must evaluate to true to continue taking elements
 Returns:
 a prefix of the given SortedSet where each element passed to the given closure evaluates to true
 Since:
 2.4.0
 - <K, V> public static Map<K, V> takeWhile(Map<K, V> self, @ClosureParams(MapEntryOrKeyValue.class) Closure condition)
 
 Returns the longest prefix of this Map where each entry (or key/value pair) when passed to the given closure evaluates to true.
```
 def shopping = [milk:1, bread:2, chocolate:3]
 assert shopping.takeWhile{ it.key.size() < 6 } == [milk:1, bread:2]
 assert shopping.takeWhile{ it.value % 2 } == [milk:1]
 assert shopping.takeWhile{ k, v -> k.size() + v <= 7 } == [milk:1, bread:2]
 
```
 If the map instance does not have ordered keys, then this function could appear to take random entries. Groovy by default uses LinkedHashMap, so this shouldn't be an issue in the main.
 Parameters:
 self - a Map
 condition - a 1 (or 2) arg Closure that must evaluate to true for the entry (or key and value) to continue taking elements
 Returns:
 a prefix of the given Map where each entry (or key/value pair) passed to the given closure evaluates to true

 append('foo')
 append('bar')
 }
 assert b.toString() == 'foobar'

 assert( list2 != list && list2 == [a, b, c] )
 
```
 Parameters:
 self - a Collection
 mutate - false will always cause a new collection to be created, true will mutate collections in place
 comparator - a Comparator
 Returns:
 self the collection without duplicates
 Since:
 1.8.1
 - <T> public static List<T> unique(List<T> self, boolean mutate, Comparator<T> comparator)
 
 Remove all duplicates from a given List. If mutate is true, it works on the original object (and also returns it). If mutate is false, a new List is returned. The order of members in the List are compared by the given Comparator. For each duplicate, the first member which is returned by the given List's iterator is retained, but all other ones are removed. The given List's original order is preserved.
```
 class Person {
 def fname, lname
 String toString() {
 return fname + " " + lname
 }
 }

 class PersonComparator implements Comparator {
 int compare(Object o1, Object o2) {
 Person p1 = (Person) o1
 Person p2 = (Person) o2
 if (p1.lname != p2.lname)
 return p1.lname.compareTo(p2.lname)
 else
 return p1.fname.compareTo(p2.fname)
 }

 boolean equals(Object obj) {
 return this.equals(obj)
 }

 - <T> public static T use(Object self, Class categoryClass, Closure<T> closure)
 
 Scoped use method
 Parameters:
 self - any Object
 categoryClass - a category class to use
 closure - the closure to invoke with the category in place

 categoryClassList - a list of category classes
 closure - the closure to invoke with the categories in place
 Returns:
 the value returned from the closure
 Since:
 1.0
 - public static Object use(Object self, Object[] array)
 
 Allows you to use a list of categories, specifying the list as varargs. use(CategoryClass1, CategoryClass2) { ... } This method saves having to wrap the category classes in a list.
 Parameters:
 self - any Object
 array - a list of category classes and a Closure
 Returns:

 Since:
 1.0
 - <T, U> @SuppressWarnings("unchecked") public static T with(@groovy.lang.DelegatesTo.Target("self") U self, @DelegatesTo(value=DelegatesTo.Target.class, target="self", strategy=Closure.DELEGATE_FIRST) @ClosureParams(FirstParam.class) Closure<T> closure)
 
 Allows the closure to be called for the object reference self.
 Any method invoked inside the closure will first be invoked on the self reference. For instance, the following method calls to the append() method are invoked on the StringBuilder instance:
```
 def b = new StringBuilder().with {
 append('foo')
 append('bar')
 return it
 }
 assert b.toString() == 'foobar'
 
```
 This is commonly used to simplify object creation, such as this example:
```
 def p = new Person().with {
 firstName = 'John'
 lastName = 'Doe'
 return it
 }
 
```
 The other typical usage, uses the self object while creating some value:
```
 def fullName = person.with{ "$firstName $lastName" }
 
```
 Parameters:
 self - the object to have a closure act upon
 closure - the closure to call on the object
 Returns:
 result of calling the closure
 See Also:
 with(Object, boolean, Closure)
 tap(Object, Closure)
 Since:
 1.5.0
 - <T, U extends T, V extends T> public static T with(@groovy.lang.DelegatesTo.Target("self") U self, boolean returning, @DelegatesTo(value=DelegatesTo.Target.class, target="self", strategy=Closure.DELEGATE_FIRST) @ClosureParams(FirstParam.class) Closure<T> closure)
 
 Allows the closure to be called for the object reference self.
 Any method invoked inside the closure will first be invoked on the self reference. For example, the following method calls to the append() method are invoked on the StringBuilder instance and then, because 'returning' is true, the self instance is returned:
```
 def b = new StringBuilder().with(true) {
 append('foo')
 append('bar')
 }
 assert b.toString() == 'foobar'
 
```
 The returning parameter is commonly set to true when using with to simplify object creation, such as this example:
```
 def p = new Person().with(true) {
 firstName = 'John'
 lastName = 'Doe'
 }
 
```
 Alternatively, 'tap' is an alias for 'with(true)', so that method can be used instead. The other main use case for with is when returning a value calculated using self as shown here:
```
 def fullName = person.with(false){ "$firstName $lastName" }
 
```
 Alternatively, 'with' is an alias for 'with(false)', so the boolean parameter can be omitted instead.
 Parameters:
 self - the object to have a closure act upon
 returning - if true, return the self object; otherwise, the result of calling the closure
 closure - the closure to call on the object
 Returns:
 the self object or the result of calling the closure depending on 'returning'

 Since:
 2.5.0
 - <K, V> public static Map<K, V> withDefault(Map<K, V> self, @ClosureParams(FirstParam.FirstGenericType.class) Closure<V> init)
 
 Wraps a map using the decorator pattern with a wrapper that intercepts all calls to get(key). If an unknown key is found, a default value will be stored into the Map before being returned. The default value stored will be the result of calling the supplied Closure with the key as the parameter to the Closure. Example usage:
```
 def map = [a:1, b:2].withDefault{ k -> k.toCharacter().isLowerCase() ? 10 : -10 }
 def expected = [a:1, b:2, c:10, D:-10]
 assert expected.every{ e -> e.value == map[e.key] }

 def constMap = [:].withDefault{ 42 }
 assert constMap.foo == 42
 assert constMap.size() == 1
 
```
 Parameters:
 self - a Map
 init - a Closure which is passed the unknown key
 Returns:
 the wrapped Map
 Since:
 1.7.1
 - <T> public static ListWithDefault<T> withDefault(List<T> self, @ClosureParams(value=SimpleType.class, options = "int") Closure<T> init)
 
 An alias for withLazyDefault which decorates a list allowing it to grow when called with index values outside the normal list bounds.
 Parameters:
 self - a List
 init - a Closure with the target index as parameter which generates the default value
 Returns:
 the decorated List
 See Also:
 withLazyDefault(java.util.List, groovy.lang.Closure)
 withEagerDefault(java.util.List, groovy.lang.Closure)
 Since:
 1.8.7
 - <T> @Deprecated public static List<T> withDefault$$bridge(List<T> self, @ClosureParams(value=SimpleType.class, options = "int") Closure<T> init)
 - <T> public static ListWithDefault<T> withEagerDefault(List<T> self, @ClosureParams(value=SimpleType.class, options="int") Closure<T> init)
 
 Decorates a list allowing it to grow when called with a non-existent index value. When called with such values, the list is grown in size and a default value is placed in the list by calling a supplied init Closure. Null values can be stored in the list.
 How it works: The decorated list intercepts all calls to getAt(index) and get(index). If an index greater than or equal to the current size() is used, the list will grow automatically up to the specified index. Gaps will be filled by calling the init Closure. If generating a default value is a costly operation consider using withLazyDefault.
 Example usage:
```
 def list = [0, 1].withEagerDefault{ 42 }
 assert list[0] == 0
 assert list[1] == 1
 assert list[3] == 42 // default value
 assert list == [0, 1, 42, 42] // gap filled with default value

 // illustrate using the index when generating default values
 def list2 = [5].withEagerDefault{ index -> index * index }
 assert list2[3] == 9
 assert list2 == [5, 1, 4, 9]

 // illustrate what happens with null values
 list2[2] = null
 assert list2[2] == null
 assert list2 == [5, 1, null, 9]
 
```
 Parameters:
 self - a List
 init - a Closure with the target index as parameter which generates the default value
 Returns:
 the wrapped List

 Since:
 2.4.0
 - <T> public static ListWithDefault<T> withLazyDefault(List<T> self, @ClosureParams(value=SimpleType.class, options="int") Closure<T> init)
 
 Decorates a list allowing it to grow when called with a non-existent index value. When called with such values, the list is grown in size and a default value is placed in the list by calling a supplied init Closure. Subsequent retrieval operations if finding a null value in the list assume it was set as null from an earlier growing operation and again call the init Closure to populate the retrieved value; consequently the list can't be used to store null values.
 How it works: The decorated list intercepts all calls to getAt(index) and get(index). If an index greater than or equal to the current size() is used, the list will grow automatically up to the specified index. Gaps will be filled by null. If a default value should also be used to fill gaps instead of null, use withEagerDefault. If getAt(index) or get(index) are called and a null value is found, it is assumed that the null value was a consequence of an earlier grow list operation and the init Closure is called to populate the value.
 Example usage:
```
 def list = [0, 1].withLazyDefault{ 42 }
 assert list[0] == 0
 assert list[1] == 1
 assert list[3] == 42 // default value
 assert list == [0, 1, null, 42] // gap filled with null

 // illustrate using the index when generating default values
 def list2 = [5].withLazyDefault{ index -> index * index }
 assert list2[3] == 9
 assert list2 == [5, null, null, 9]
 assert list2[2] == 4
 assert list2 == [5, null, 4, 9]

 // illustrate what happens with null values
 list2[2] = null
 assert list2[2] == 4

 self - a List
 init - a Closure with the target index as parameter which generates the default value
