Constructor Details

EqualityFilterNode

public EqualityFilterNode(ReteContainer reteContainer,
 int[] indices)

Parameters:

reteContainer -

indices - indices of the Tuple that should hold equal values

Method Details

check

public boolean check(Tuple ps)

Description copied from class: FilterNode

Abstract filtering predicate. Expected to be stateless.

Specified by:

check in class FilterNode

Parameters:

ps - the matching to be checked.
