Method Detail

getId

public java.lang.String getId()

getExtension

public Extension getExtension()

getRuleFunction

public RuleFunction getRuleFunction()
                             throws RuleEvaluationException

Attempts to instantiate the RuleFunction class associated with this RuleType. A RuleEvaluationException will be thrown if the specified rule class cannot be instantiated, or if the extension that defined this rule-type is not fully loaded (evaluating a rule is not allowed to trigger fully loading an extension).

Returns:

Throws:

RuleEvaluationException

public boolean isParameterSupported(java.lang.String paramName)

getSupportedParameters

public java.util.Collection<RuleTypeParameter> getSupportedParameters()

hasRequiredParameters

public boolean hasRequiredParameters()

addSupportedParameter

public boolean addSupportedParameter(RuleTypeParameter parameter)

Attempts to add a parameter to this rule-type definition, returns false if a parameter with the same name already existed.

Parameters:
