Constructor Details

WrappedArray

protected WrappedArray(T[] array)

Internal constructor for Conversions.WrappedArray.

Parameters:

array - the to-be-wrapped array. May be null which will cause any method on the created object to fail with a NullPointerException.

Method Details

create

public static <T> Conversions.WrappedArray<T> create(T[] array)

Creates a new Conversions.WrappedArray that is backed by the given array.

Type Parameters:

T - the element type of the created list.

Parameters:

array - the to-be-wrapped array. May be null which will cause any method on the result object to fail with a NullPointerException.

Returns:

the wrapped array. Never null.

get

public T get(int index)

Specified by:

Throws:

NullPointerException - if the wrapped array was null.

IndexOutOfBoundsException

set

public T set(int index,
 T element)

Specified by:

Throws:

NullPointerException - if the wrapped array was null.

toArray

public Object[] toArray()

Specified by:

toArray in interface List<T>

Overrides:

toArray in class AbstractCollection<T>

internalToArray

public T[] internalToArray()

Returns the underlying array in an unsafe manner. That is, modification of the array will be reflected by this list and vice versa.

Returns:

the underlying array. May be null if the list was created with a null argument.
