Method Detail

isInnerReference

public static boolean isInnerReference(de.uka.ipd.sdq.stoex.AbstractNamedReference reference)

Returns whether the specified reference belongs to an INNER variable characterisation.

Parameters:

reference - the named reference associated with a variable characterisation

Returns:

true, if the reference's name is "INNER"; false else.

getVariableName

public static String getVariableName(de.uka.ipd.sdq.stoex.AbstractNamedReference reference)

Returns the name for the specified named reference.

Parameters:

reference - the named reference

Returns:

the name

evaluateParametersAndCopyToFrame

public static void evaluateParametersAndCopyToFrame(List<org.palladiosimulator.pcm.parameter.VariableUsage> parameters,
                                                    de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStackframe<Object> sourceFrame,
                                                    de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStackframe<Object> targetFrame)

Evaluates the passed parameters in the context of the source frame and copies the results to the targetFrame. INNER characterisations are not evaluated directly, but are instead encapsulated in an EvaluationProxy which are being repeatedly evaluated on each access.

createEvaluationProxiesAndCopyToFrame

public static void createEvaluationProxiesAndCopyToFrame(List<org.palladiosimulator.pcm.parameter.VariableUsage> parameters,
                                                         de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStackframe<Object> targetFrame)

Creates an EvaluationProxy for the passed parameters and copies them to the targetFrame. The proxy evaluates the passed parameters on each access.
