Constructor Details

ValueBinderFilterNode

public ValueBinderFilterNode(ReteContainer reteContainer,
 int bindingIndex,
 Object bindingValue)

Parameters:

reteContainer -

bindingIndex - the position in the tuple that should be bound

bindingValue - the value to which the tuple has to be bound

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.
