public class ExternalInputStatelessFilterNode extends FilterNode implements Disconnectable
A filter node representing a (stateless, typically non-enumerable) extensional input relation.Contains those tuples of its parents, that (when transformed by a mask, if given) are present in the extensional relation identified by the input key.

Method Detail
-
check
public boolean check(Tuple ps)
Description copied from class:FilterNode
Abstract filtering predicate. Expected to be stateless.- Specified by:
check
in classFilterNode
- Parameters:
ps
- the matching to be checked.- Returns:
- true if and only if the parameter matching is allowed to pass through this node.
-
connectThroughContext
public void connectThroughContext(ReteEngine engine, IInputKey inputKey)
-
disconnect
public void disconnect()
Description copied from interface:Disconnectable
Disconnects this rete engine component from the underlying model. Disconnecting enables the garbage collection mechanisms to dispose of the rete network.- Specified by:
disconnect
in interfaceDisconnectable
