Constructor Detail

AbstractTupleEvent

public AbstractTupleEvent(Object source,
                          Long key,
                          Tuple tuple,
                          Tuple keyData,
                          List<TupleFieldComparator> fieldComparators)

Parameters:

source - the source that generated the event

key - the key of the tuple

tuple - the tuple

fieldComparators - TODO

Method Detail

getKey

public final Long getKey()

Deprecated. since 1.6, use AbstractTupleEvent.getKeyValue() instead; certain table types and queries have undefined return values

Get the key of the tuple in this event, if applicable

Returns:

the key of the tuple as a Long, if applicable

setKey

final void setKey(Long key)

getTuple

public final Tuple getTuple()

Get the tuple

Returns:

the tuple

getKeyValue

public final KeyValue getKeyValue()

This replaces AbstractTupleEvent.getKey() now that there is support for complex keys

Returns:

A representative of this Tuple's value for the key, based on whatever the key field(s) are for this Table.

Since:

1.6

getComparators

List<TupleFieldComparator> getComparators()
