Method Details

evaluate

public PropositionResult evaluate(org.kuali.rice.krms.api.engine.ExecutionEnvironment environment)

Description copied from interface: Proposition

Evaluates this proposition -- and in the case of Propositions containing children, those children as well -- and returns the boolean result;

Specified by:

evaluate in interface Proposition

Parameters:

environment - the ExecutionEnvironment that this Proposition is running in

Returns:

the boolean result of evaluation

logPropositionResult

public void logPropositionResult(Proposition proposition,
 PropositionResult propositionResult,
 org.kuali.rice.krms.api.engine.ExecutionEnvironment environment)

getChildren

public List<Proposition> getChildren()

Returns an unmodifiableList of Propositions.

Specified by:

getChildren in interface Proposition

Returns:

an unmodifiableList of Propositions

isCompound

public boolean isCompound()

Description copied from interface: Proposition

Indicates whether this Proposition can have children.

Specified by:

isCompound in interface Proposition

Returns:

true if this Proposition can contain child Propositions.
