DefaultGroovyMethods (Groovy 2.4.13)

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.

public static boolean is(java.lang.Object self,
                         java.lang.Object other)
```
    Identity check. Since == is overridden in Groovy with the meaning of equality we need some fallback to check for object identity. Invoke using the 'is' method, like so: def same = this.is(that)
    
    Parameters:
    
    self - an object
    
    other - an object to compare identity with
    
    Returns:
    
    true if self and other are both references to the same instance, false otherwise
    
    Since:
    
    1.0
  - identity
```
public static <T> T identity(java.lang.Object self,
                             Closure<T> closure)
```
    Allows the closure to be called for the object reference self. Synonym for 'with()'.
    
    Parameters:
    
    self - the object to have a closure act upon
    
    closure - the closure to call on the object
    
    Returns:
    
    result of calling the closure
    
    Since:
    
    1.0
  - with
```
public static <T,U> T with(U self,
                           @DelegatesTo(value=DelegatesTo.Target.class,target="self",strategy=1)
                           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
 }
 
```
    Parameters:
    
    self - the object to have a closure act upon
    
    closure - the closure to call on the object

```
    Returns an iterator equivalent to this iterator but with all duplicated items removed by using a Closure to determine duplicate (equal) items. The original iterator will be fully processed after the call.
    If the closure takes a single parameter, the argument passed will be each element, and the closure should return a value used for comparison (either using Comparable.compareTo(java.lang.Object) or Object.equals(java.lang.Object)). If the closure takes two parameters, two items from the Iterator will be passed as arguments, and the closure should return an int value (with 0 indicating the items are not unique).
    
    Parameters:
    
    self - an Iterator
    
    closure - a Closure used to determine unique items

    Note: When using the list-style of result, the behavior is 'def (key, value) = listResultFromClosure'. While we strongly discourage using a list of size other than 2, Groovy's normal semantics apply in this case; throwing away elements after the second one and using null for the key or value for the case of a shortened list. If your collector Map doesn't support null keys or values, you might get a runtime error, e.g. NullPointerException or IllegalArgumentException.
    Parameters:
    
    self - a Map
    
    collector - the Map into which the transformed entries are put
    
    transform - the closure used for transforming, which can take one (Map.Entry) or two (key, value) parameters and should return a Map.Entry, a Map or a two-element list containing the resulting key and value

                                                        Closure<?> transform)
```
    Iterates through this array transforming each item using the transform closure and returning a map of the resulting transformed entries.
```
 def letters = "abc"
 def nums = [0, 1, 2] as Integer[]
 // collect letters with index using list style
 assert nums.collectEntries { index -> [index, letters[index]] } == [0:'a', 1:'b', 2:'c']
 // collect letters with index using map style
 assert nums.collectEntries { index -> [(index): letters[index]] } == [0:'a', 1:'b', 2:'c']
 
```
    Note: When using the list-style of result, the behavior is 'def (key, value) = listResultFromClosure'. While we strongly discourage using a list of size other than 2, Groovy's normal semantics apply in this case; throwing away elements after the second one and using null for the key or value for the case of a shortened list.
    Parameters:
    
    self - a Collection
    
    transform - the closure used for transforming, which has an item from self as the parameter and should return a Map.Entry, a Map or a two-element list containing the resulting key and value

    Modifies the collection by adding all of 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

```
    Modifies this list by inserting all of 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

    Iterates through the given Object, passing in the initial value to the closure along with the first item. The result is passed back (injected) into the closure along with the second item. The new result is injected back into the closure along with the third item and so on until further iteration of the object is not possible. Also known as foldLeft in functional parlance.
    
    Parameters:
    
    self - an Object
    
    initialValue - some initial value
    
    closure - a closure
    
    Returns:

    Selects the item in the iterable which when passed as a parameter to the supplied closure returns the minimum value. A null return value represents the least possible return value. If more than one item has the minimum value, an arbitrary choice is made between the items having the minimum 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.

                          int idx)
```
    Support the subscript operator for an Iterator. The iterator will be partially exhausted up until the idx entry after returning if a +ve or 0 idx is used, or fully exhausted if a -ve idx is used or no corresponding entry was found. Typical usage:

    A more elaborate example:
```
 def items = [2, "a", 5.3]
 def iter = items.iterator()
 assert iter[-1] == 5.3
 // iter exhausted, so reset
 iter = items.iterator()
 assert iter[1] == "a"
 // iter partially exhausted so now idx starts after "a"
 assert iter[0] == 5.3
