- Methods Detail
  - public boolean addAll(int index, Object[] items)
    
    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:
    
    items - array containing elements to be added to this collection
    
    index - index at which to insert the first element from the specified array
    
    Returns:
    
    true if this collection changed as a result of the call

  - public List unique(boolean mutate, Closure closure)
    
    A convenience method for making a List unique using a Closure to determine duplicate (equal) items. If mutate is true, it works on the receiver object and returns it. If mutate is false, a new collection is returned.
    If the closure takes a single parameter, each element from the List will be passed to the closure. 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 collection will be passed as arguments, and the closure should return an int value (with 0 indicating the items are not unique).
```
def orig = [1, 3, 4, 5]
def uniq = orig.unique(false) { it % 2 }
assert orig == [1, 3, 4, 5]
assert uniq == [1, 4]
```
```
def orig = [2, 3, 3, 4]
def uniq = orig.unique(false) { a, b -> a <=> b }
assert orig == [2, 3, 3, 4]
assert uniq == [2, 3, 4]
```
    Parameters:
    
    mutate - false will always cause a new list to be created, true will mutate lists in place
    
    closure - a 1 or 2 arg Closure used to determine unique items
    
    Returns:
    
    self without any duplicates

  - public List unique(boolean mutate, Comparator 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)
    }
}

Person a = new Person(fname:"John", lname:"Taylor")
Person b = new Person(fname:"Clark", lname:"Taylor")
Person c = new Person(fname:"Tom", lname:"Cruz")
Person d = new Person(fname:"Clark", lname:"Taylor")

def list = [a, b, c, d]
List list2 = list.unique(false, new PersonComparator())
assert( list2 != list && list2 == [a, b, c] )
```
    Parameters:
    
    mutate - false will always cause a new List to be created, true will mutate List in place
    
    comparator - a Comparator
    
    Returns:
    
    self the List without duplicates

  - public ListWithDefault withDefault(Closure init)
    
    An alias for withLazyDefault which decorates a list allowing it to grow when called with index values outside the normal list bounds.
    
    Parameters:
    
    init - a Closure with the target index as parameter which generates the default value
    
    Returns:
    
    the decorated List

    List#withLazyDefault(groovy.lang.Closure)
    
    List#withEagerDefault(groovy.lang.Closure)
  - public ListWithDefault withEagerDefault(Closure 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:
    
    init - a Closure with the target index as parameter which generates the default value
    
    Returns:
    
    the wrapped List
    
    Since:
    
    1.8.7
  - public ListWithDefault withLazyDefault(Closure 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
```
    Parameters:
    
    init - a Closure with the target index as parameter which generates the default value
    
    Returns:
    
    the decorated List
