Constructor Detail

DefaultTransactionalSet

public DefaultTransactionalSet(String name,
                               TransactionContext txContext,
                               Serializer serializer)

Method Detail

add

public boolean add(E e)

Description copied from interface: TransactionalSet

Adds the specified element to this set if it is not already present (optional operation). More formally, adds the specified element e to this set if the set contains no element e2 such that (e==null ? e2==null : e.equals(e2)). If this set already contains the element, the call leaves the set unchanged and returns false. In combination with the restriction on constructors, this ensures that sets never contain duplicate elements.

Specified by:

add in interface TransactionalSet<E>

Parameters:

e - element to be added to this set

Returns:

true if this set did not already contain the specified element

remove

public boolean remove(E e)

Description copied from interface: TransactionalSet

Removes the specified element from this set if it is present (optional operation). More formally, removes an element e such that (o==null ? e==null : o.equals(e)), if this set contains such an element. Returns true if this set contained the element (or equivalently, if this set changed as a result of the call). (This set will not contain the element once the call returns.)

Specified by:

remove in interface TransactionalSet<E>

Parameters:

e - element to be removed to this set

Returns:

true if this set contained the specified element

contains

public boolean contains(E e)

Description copied from interface: TransactionalSet

Returns true if this set contains the specified element. More formally, returns true if and only if this set contains an element e such that (o==null ? e==null : o.equals(e)).

Specified by:

contains in interface TransactionalSet<E>

Parameters:

e - element whose presence in this set is to be tested

Returns:

true if this set contains the specified element
