WeakSet

public WeakSet()

Method Detail

maybeWarnAboutAnonymousValue NEW

protected void maybeWarnAboutAnonymousValue(T t)

Looks for situations where clients may lose the values added to this class. This most often happens when a client adds an anonymous, local listener to an object that is using a WeakSet to store its listeners. Our policy is to implement listeners at the class field level so that they will not be flagged by this method.

Parameters:

t - The object to check

add

public abstract void add(T t)

Add the given object to the set.

remove

public abstract void remove(T t)

Remove the given object from the data structure

contains

public abstract boolean contains(T t)

Returns true if the given object is in this data structure

clear

public abstract void clear()

Remove all elements from this data structure

size

public abstract int size()

Return the number of objects contained within this data structure

isEmpty

public abstract boolean isEmpty()

Return whether this data structure is empty.

values

public abstract java.util.Collection<T> values()

Returns a Collection view of this set. The returned Collection is backed by this set.

Returns:

a Collection view of this set. The returned Collection is backed by this set.

stream

public java.util.stream.Stream<T> stream()

Returns a stream of the values of this collection.

Returns:

a stream of the values of this collection.
