Assemble elements of the rule that will process this stream and turn it into a constraint match. Will be ignored unless on a scoring stream such as DroolsScoringUniConstraintStream.

Parameters:

constraint - constraint which is being scored

scoreHolderGlobal - contains the score to be affected

Returns:

rule representing this constraint stream

getConstraintFactory

public DroolsConstraintFactory<Solution_> getConstraintFactory()

Description copied from interface: ConstraintStream

The ConstraintFactory that build this.

Specified by:

getConstraintFactory in interface ConstraintStream

Specified by:

getConstraintFactory in class AbstractConstraintStream<Solution_>

Returns:

never null

getExpectedJustificationTypes

public Class[] getExpectedJustificationTypes()

As defined by DroolsRuleStructure.getExpectedJustificationTypes(). May only be called on scoring streams.

Returns:

never null, never empty
