public WeakSet()

Method Details

maybeWarnAboutAnonymousValue

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 boolean add(T t)

Add the given object to the set

Specified by:

add in interface Collection<T>

Specified by:

add in interface Set<T>
