Class DelayedRemovalArray<T>

java.lang.Object

com.badlogic.gdx.utils.Array<T>

com.badlogic.gdx.utils.DelayedRemovalArray<T>

All Implemented Interfaces:

java.lang.Iterable<T>

public class DelayedRemovalArray<T>
extends Array<T>

Queues any removals done after begin() is called to occur once end() is called. This can allow code out of your control to remove items without affecting iteration. Between begin and end, most mutator methods will throw IllegalStateException. Only removeIndex(int), removeValue(Object, boolean), removeRange(int, int), clear(), and add methods are allowed.

Code using this class must not rely on items being removed immediately. Consider using SnapshotArray if this is a problem.

Method Detail

begin

public void begin()

end

public void end()

removeValue

public boolean removeValue(T value,
                           boolean identity)

Description copied from class: Array

Removes the first instance of the specified value in the array.

Overrides:

removeValue in class Array<T>

Parameters:

value - May be null.

identity - If true, == comparison will be used. If false, .equals() comparison will be used.

Returns:

true if value was found and removed, false otherwise

removeIndex

public T removeIndex(int index)

Description copied from class: Array

Removes and returns the item at the specified index.

Overrides:

removeIndex in class Array<T>

removeRange

public void removeRange(int start,
                        int end)

Description copied from class: Array

Removes the items between the specified indices, inclusive.

Overrides:

removeRange in class Array<T>

clear

public void clear()

Overrides:

clear in class Array<T>

set

public void set(int index,
                T value)

Overrides:

set in class Array<T>

insert

public void insert(int index,
                   T value)

Overrides:

insert in class Array<T>

swap

public void swap(int first,
                 int second)

Overrides:

swap in class Array<T>

pop

public T pop()

Description copied from class: Array

Removes and returns the last item.

Overrides:

pop in class Array<T>

sort

public void sort()

Description copied from class: Array

Sorts this array. The array elements must implement Comparable. This method is not thread safe (uses Sort.instance()).

Overrides:

sort in class Array<T>

sort

public void sort(java.util.Comparator<? super T> comparator)

Description copied from class: Array

Sorts the array. This method is not thread safe (uses Sort.instance()).

Overrides:

sort in class Array<T>

reverse

public void reverse()

Overrides:

reverse in class Array<T>

shuffle

public void shuffle()

Overrides:

shuffle in class Array<T>

truncate

public void truncate(int newSize)

Description copied from class: Array

Reduces the size of the array to the specified size. If the array is already smaller than the specified size, no action is taken.

Overrides:

truncate in class Array<T>

setSize

public T[] setSize(int newSize)

Description copied from class: Array

Sets the array size, leaving any values beyond the current size null.

Overrides:

setSize in class Array<T>

Returns:

Array.items
