Modifier and Type	Method and Description
static <T> ArrayList<T>	asList(T[] array) Given an input array, will return an ArrayList representation of the array.
static <T,O> ArrayList<T>	collect(Object[] array, TypedTransformer<T> transformer) Similar to the CollectionUtils collect except that it works on an array instead of a Java Collection
static <T,O> HashSet<T>	collectSet(Object[] array, TypedTransformer<T> transformer) The same as collect(Object[], TypedTransformer) but returns a set.
static <T> boolean	contains(T[] array, TypedPredicate<T> predicate) Given an array and a typed predicate, determines if the array has an object that matches the condition of the predicate.

Method Detail

contains

public static <T> boolean contains(T[] array,
                                   TypedPredicate<T> predicate)

Given an array and a typed predicate, determines if the array has an object that matches the condition of the predicate. The predicate should evaluate to true when a match occurs.

Parameters:

array -

predicate -

Returns:

whether or not the array contains an element that matches the predicate

asList

public static <T> ArrayList<T> asList(T[] array)

Given an input array, will return an ArrayList representation of the array.

Parameters:

array -

Returns:

the ArrayList corresponding to the input array. If the input is null, this also returns null. If it is empty then this will return an empty list

collect

public static <T,O> ArrayList<T> collect(Object[] array,
                                         TypedTransformer<T> transformer)

Similar to the CollectionUtils collect except that it works on an array instead of a Java Collection

Parameters:

array -

transformer -

Returns:

the transformed collection

collectSet

public static <T,O> HashSet<T> collectSet(Object[] array,
                                          TypedTransformer<T> transformer)

The same as collect(Object[], TypedTransformer) but returns a set.

Parameters:

array -

transformer -

Returns:

the transformed set
