Method Detail

addParameterToStackFrame

public static final void addParameterToStackFrame(de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStackframe<Object> contextStackFrame,
                                                  EList<org.palladiosimulator.pcm.parameter.VariableUsage> parameter,
                                                  de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStackframe<Object> targetStackFrame)

Adds parameters to given stack frame.

Parameters:

parameter - the parameter.

targetStackFrame - the stack frame.

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.

createAndPushNewStackFrame

public static final de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStackframe<Object> createAndPushNewStackFrame(de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStack<Object> stack,
                                                                                                                                EList<org.palladiosimulator.pcm.parameter.VariableUsage> parameter)

Convenience method creating new stack frame, adds it to stack and puts parameters into frame. This method uses own stack for parameter evaluation.

Parameters:

parameter - the parameter.

Returns:

the created stack frame.

createAndPushNewStackFrame

public static final de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStackframe<Object> createAndPushNewStackFrame(de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStack<Object> stack,
                                                                                                                                EList<org.palladiosimulator.pcm.parameter.VariableUsage> parameter,
                                                                                                                                de.uka.ipd.sdq.simucomframework.variables.stackframe.SimulatedStackframe<Object> parent)

Convenience method creating new stack frame with parent, adds it to stack and puts parameters into frame. This method uses own stack for parameter evaluation.

Parameters:

parameter - the parameter.

parent - the parent, if null no parent will be set.

Returns:

the created stack frame.
