Method Detail

getLog

protected Logger getLog()

getTransaction

protected TransactionImpl getTransaction()

getPBKey

public PBKey getPBKey()

setPBKey

public void setPBKey(PBKey pbKey)

prepareEntry

protected DMapEntry prepareEntry(Object key,
                                 Object value)

entrySet

public Set entrySet()

Returns a set view of the mappings contained in this map. Each element in the returned set is a Map.Entry. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress, the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Specified by:

entrySet in interface Map

Specified by:

entrySet in class AbstractMap

Returns:

a set view of the mappings contained in this map.

getId

public Integer getId()

lazily retrieve the ID of the set, no need to precompute it.

put

public Object put(Object key,
                  Object value)

Specified by:

put in interface Map

Overrides:

put in class AbstractMap

remove

public Object remove(Object key)

Specified by:

remove in interface Map

Overrides:

remove in class AbstractMap

getEntries

public Set getEntries()

Gets the entries.

Returns:

Returns a Set

setEntries

public void setEntries(ManageableHashSet entries)

Sets the entries.

Parameters:

entries - The entries to set

setId

public void setId(Integer id)

Sets the id.

Parameters:

id - The id to set

beforeInsert

public void beforeInsert(PersistenceBroker broker)
                  throws PersistenceBrokerException

broker - The persistence broker performing the persistence operation

Throws:

PersistenceBrokerException

beforeUpdate

public void beforeUpdate(PersistenceBroker broker)
                  throws PersistenceBrokerException

noop

Specified by:

beforeUpdate in interface PersistenceBrokerAware

Parameters:

broker - The persistence broker performing the persistence operation

Throws:

PersistenceBrokerException

beforeDelete

public void beforeDelete(PersistenceBroker broker)
                  throws PersistenceBrokerException

noop

Specified by:

beforeDelete in interface PersistenceBrokerAware

Parameters:

broker - The persistence broker performing the persistence operation

                 throws PersistenceBrokerException

noop

Specified by:

afterUpdate in interface PersistenceBrokerAware

Parameters:

broker - The persistence broker performed the persistence operation

Throws:

Specified by:

afterDelete in interface PersistenceBrokerAware

Parameters:

broker - The persistence broker performing the persistence operation

Throws:

PersistenceBrokerException

afterLookup
