Interface MultiHashMapListener

public interface MultiHashMapListener

A hook to receive notification when attribute values are set and removed from objects.

Method Summary

void	allAttributeValuesRemoved(String objectKey, String attributeName) This listener method gets called as a result of MultiHashMap.removeAllAttributeValues(objectKey, attributeName), but only if objectKey has at least one attribute value bound in attributeName.
void	attributeValueAssigned(String objectKey, String attributeName, Object[] keyIntoValue, Object oldAttributeValue, Object newAttributeValue)
void	attributeValueRemoved(String objectKey, String attributeName, Object[] keyIntoValue, Object attributeValue) This listener method gets called as a result of MultiHashMap.removeAttributeValue(objectKey, attributeName, keyIntoValue), but only if an attribute value was found [and removed] for specified key.

Method Detail

attributeValueAssigned

public void attributeValueAssigned(String objectKey,
                                   String attributeName,
                                   Object[] keyIntoValue,
                                   Object oldAttributeValue,
                                   Object newAttributeValue)

Parameters:

keyIntoValue - don't modify this array; this array will be null if attributeName has a zero-dimensional keyspace.

oldAttributeValue - the previous attribute value that was bound at specified key sequence, or null if no previous attribute value was bound.

newAttributeValue - the new attribute value that is now bound at specified key sequence.

attributeValueRemoved

public void attributeValueRemoved(String objectKey,
                                  String attributeName,
                                  Object[] keyIntoValue,
                                  Object attributeValue)

This listener method gets called as a result of MultiHashMap.removeAttributeValue(objectKey, attributeName, keyIntoValue), but only if an attribute value was found [and removed] for specified key. The parameter attributeValue in this listener method is the value that is returned by MultiHashMap.removeAttributeValue(), and it is never null.

Parameters:

keyIntoValue - don't modify this array; this array will be null if attributeName has a zero-dimensional keyspace.

allAttributeValuesRemoved

public void allAttributeValuesRemoved(String objectKey,
                                      String attributeName)

This listener method gets called as a result of MultiHashMap.removeAllAttributeValues(objectKey, attributeName), but only if objectKey has at least one attribute value bound in attributeName.
