Class FactPattern

java.lang.Object

org.drools.workbench.models.datamodel.rule.FactPattern

All Implemented Interfaces:

HasCEPWindow, HasConstraints, IFactPattern, IPattern

public class FactPattern
extends Object
implements IFactPattern, HasCEPWindow, HasConstraints

A fact pattern is a declaration of a fact type, and its constraint, and perhaps a variable that is it bound to It is the equivalent of a "pattern" in drools terms.

Method Detail

getBoundName

public String getBoundName()

setBoundName

public void setBoundName(String boundName)

isNegated

public boolean isNegated()

setNegated

public void setNegated(boolean isNegated)

addConstraint

public void addConstraint(FieldConstraint constraint)

This will add a top level constraint.

Specified by:

addConstraint in interface HasConstraints

removeConstraint

public void removeConstraint(int idx)

Specified by:

removeConstraint in interface HasConstraints

isBound

public boolean isBound()

Returns true if there is a variable bound to this fact.

getFieldConstraints
