List of clearIndexKey() Examples

Examples of clearIndexKey()

com.sleepycat.bdb.bind.KeyExtractor.clearIndexKey()
Clears the index key in a value buffer. The index key is cleared when the index is for a foreign key identifying a record that has been deleted. This method is called only if the {@link com.sleepycat.bdb.ForeignKeyIndex} is configured with {@link com.sleepycat.bdb.ForeignKeyIndex#ON_DELETE_CLEAR}. It is never called for index keys that are derived from primary key data, since in this case {@link com.sleepycat.bdb.ForeignKeyIndex#ON_DELETE_CLEAR} is notallowed. @param valueData is the source and destination value data. On entrythis contains the index key to be cleared. It should be changed by this method such that {@link #extractIndexKey} will extract a null key (setthe buffer length to zero). Other data in the buffer should remain unchanged.
com.sleepycat.bdb.bind.serial.TupleSerialMarshalledKeyExtractor.clearIndexKey()
com.sleepycat.bdb.bind.tuple.MarshalledTupleKeyEntity.clearIndexKey()
Clears the entity's index key value for the given key name. This method is called when the entity for this foreign key is deleted, if ON_DELETE_CLEAR was specified when creating the index. @param keyName identifies the index key.
