Methods

Modifier and Type	Method and Description
protected java.util.Set<Variable>	calculateEnteringScope(OperationBodyToCallMapper operationBodyToCallMapper) Calculates the scopes the NavigationStep this Tracer creates will enter when navigated.
protected java.util.Set<Variable>	calculateLeavingScopes(OperationBodyToCallMapper operationBodyToCallMapper) When tracing into the called operation's body, all variables currently in scope are left.
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.

Method Detail

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<OperationCallExp>

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<OperationCallExp>

Returns:

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

calculateLeavingScopes

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

When tracing into the called operation's body, all variables currently in scope are left.

Overrides:

calculateLeavingScopes in class AbstractTracer<OperationCallExp>

Returns:

the set of OCLExpressions representing the scopes the created NavigationStep will leave when navigated.
