              org.eclipse.ocl.examples.impactanalyzer.ValueNotFoundException

All Implemented Interfaces:

java.io.Serializable, VariableValueNotFoundInfo

public class ValueNotFoundException
extends java.lang.RuntimeException
implements VariableValueNotFoundInfo

Thrown when during (partial) OCL evaluation the value of a yet undefined variable is requested from the EvaluationEnvironment. Normally, this exception is expected to occur only when the PartialEvaluatorImpl together with a PartialEcoreEvaluationEnvironment is used. In this case, the VariableExp is remembered together with the variable name. Only in case of an ill-defined configuration would it be possible that the VariableExp is not set and that only the variable name is set.

Method Detail

getVariableName

public java.lang.String getVariableName()

Specified by:

getVariableName in interface VariableValueNotFoundInfo

getVariableExp

public VariableExp<org.eclipse.emf.ecore.EClassifier,org.eclipse.emf.ecore.EParameter> getVariableExp()

If the request for the undefined variable was triggered by evaluating a VariableExp, this expression is returned. In some cases the EvaluationEnvironment.getValueOf(String) method is called without a particular variable expression at hand, e.g., in order to look up the context object which is the value of the "self" variable for which not always a variable expression is available. In those cases, null will be returned.
