Method Summary

protected java.util.Set<Variable>	calculateEnteringScope(OperationBodyToCallMapper operationBodyToCallMapper) Calculates the scopes the NavigationStep this Tracer creates will enter when navigated.
NavigationStep	traceback(org.eclipse.emf.ecore.EClass context, PathCache pathCache, OperationBodyToCallMapper operationBodyToCallMapper) By default, many expression types which, e.g., result in a primitive result, return an EmptyResultNavigationStep which is what this default implementation does.

traceback

public NavigationStep traceback(org.eclipse.emf.ecore.EClass context,
                                PathCache pathCache,
                                OperationBodyToCallMapper operationBodyToCallMapper)

Description copied from class: AbstractTracer

By default, many expression types which, e.g., result in a primitive result, return an EmptyResultNavigationStep which is what this default implementation does.

Specified by:

traceback in interface Tracer

Overrides:

traceback in class AbstractTracer<IterateExp>

Parameters:

context - the context type that defines the type of any self occurrence outside of operation bodies

pathCache - a global cache that remembers the navigation steps already computed for some OCL expressions

operationBodyToCallMapper - the filter synthesizer that analyzed an overall expression that contains the expression to be handled by this tracer

calculateEnteringScope

protected java.util.Set<Variable> calculateEnteringScope(OperationBodyToCallMapper operationBodyToCallMapper)

Description copied from class: AbstractTracer

Calculates the scopes the NavigationStep this Tracer creates will enter when navigated.

Overrides:

calculateEnteringScope in class AbstractTracer<IterateExp>

Returns:

the OCLExpressions representing the scope the created NavigationStep will enter when navigated. Always non-null, but possibly empty
