Method Detail

add

public boolean add(Txn tx,
          E e)

Description copied from interface: TxnCollection

Ensures that this collection contains the specified element (optional operation). Returns true if this collection changed as a result of the call. (Returns false if this collection does not permit duplicates and already contains the specified element.)

Collections that support this operation may place limitations on what elements may be added to this collection. In particular, some collections will refuse to add null elements, and others will impose restrictions on the type of elements that may be added. Collection classes should clearly specify in their documentation any restrictions on what elements may be added.

If a collection refuses to add a particular element for any reason other than that it already contains the element, it must throw an exception (rather than returning false). This preserves the invariant that a collection always contains the specified element after this call returns.

Specified by:

add in interface TxnCollection<E>

Parameters:

tx - the transaction used for this operation.

e - element whose presence in this collection is to be ensured

Returns:

true if this collection changed as a result of the call

contains

public boolean contains(java.lang.Object item)

Specified by:

contains in interface java.util.Collection<E>

Specified by:

contains in interface java.util.Set<E>

Overrides:

contains in class AbstractTxnCollection<E>

contains

public boolean contains(Txn tx,
               java.lang.Object o)

Description copied from interface: TxnCollection

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

Specified by:

contains in interface TxnCollection<E>

Parameters:

tx - the transaction used for this operation.

o - element whose presence in this collection is to be tested

Returns:

true if this collection contains the specified element

remove

public boolean remove(java.lang.Object item)

Specified by:

remove in interface java.util.Collection<E>

Specified by:

remove in interface java.util.Set<E>

Overrides:

remove in class AbstractTxnCollection<E>

remove

public boolean remove(Txn tx,
             java.lang.Object item)

Description copied from interface: TxnCollection

Removes a single instance of the specified element from this collection, if it is present (optional operation). More formally, removes an element e such that (o==null ? e==null : o.equals(e)), if this collection contains one or more such elements. Returns true if this collection contained the specified element (or equivalently, if this collection changed as a result of the call).

Specified by:

remove in interface TxnCollection<E>

Parameters:

tx - the transaction used for this operation.

item - element to be removed from this collection, if present

Returns:

true if an element was removed as a result of this call

size

public int size(Txn tx)

Description copied from interface: TxnCollection

Returns the number of elements in this collection. If this collection contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Specified by:

size in interface TxnCollection<E>

Parameters:

tx - the transaction used for this operation.

Returns:

the number of elements in this collection

clear

public void clear(Txn tx)

Description copied from interface: TxnCollection

Removes all of the elements from this collection (optional operation). The collection will be empty after this method returns.

Specified by:

clear in interface TxnCollection<E>

Parameters:

tx - the transaction used for this operation.

iterator

public TxnIterator<E> iterator(Txn tx)

Description copied from interface: TxnIterable

Returns an iterator over a set of elements of type T.

Specified by:

iterator in interface TxnIterable<E>

Parameters:

tx - the Txn used for this Operation.

Returns:

an Iterator.

toString

public java.lang.String toString(Txn tx)

Specified by:

toString in interface TxnCollection<E>
