Method Detail

getInstanceOrCopyIfMutable

public java.util.Optional<ReflectionExecutor.InstanceCopyResult> getInstanceOrCopyIfMutable(ReferenceValue instanceValue)

Description copied from class: ReflectionExecutor

Get an object which will act as the calling instance. If we know that executing the method does not modify the instance this can just be the same value. Otherwise, a copy should be returned in order to not change the reference whose state may be of interest at the end of an analysis.

Specified by:

getInstanceOrCopyIfMutable in class ReflectionExecutor

Parameters:

instanceValue - The ReferenceValue of the instance.

Returns:

The new calling instance.

getExecutorMatcher

public ExecutorMatcher getExecutorMatcher()

Description copied from interface: Executor

Get a matcher telling if the executor should be used to execute a certain method.

Returns:

the executor's matcher.

getDefaultInstanceHandler

public ExecutorInstanceHandler getDefaultInstanceHandler()

Description copied from class: ReflectionExecutor

Provides a default instance handler used by the executor in case the reflective execution fails.

The handler carries information on whether a method returns the same object as its instance.

Specified by:

getDefaultInstanceHandler in class ReflectionExecutor

Returns:

the default instance handler.
