Overrides:

add in class AbstractReferenceCollection<K>

contains

public boolean contains(java.lang.Object k)

Specified by:

contains in interface java.util.Collection<K>

Adds all elements of the given collection to this collection.

Specified by:

addAll in interface java.util.Collection<K>

Specified by:

addAll in interface java.util.Set<K>

Overrides:

addAll in class AbstractReferenceCollection<K>

a type-specific iterator.

size

public int size()

Specified by:

size in interface java.util.Collection<K>

Specified by:

size in interface java.util.Set<K>

clone

public java.lang.Object clone()

Overrides:
