trait RecordReturnedValue extends RecordReturnedValuesInfrastructure

Record the value returned by a method across all return instructions.

Usage

This domain can be stacked on top of other traits that handle return instructions that return some value.

Usage

A domain that mixes in this trait should only be used to analyze a single method.

    This type determines in which way the returned values are recorded.

    This type determines in which way the returned values are recorded.

    For example, if it is sufficient to just record the last value that was returned by a specific return instruction, then the type could be DomainValue and the implementation of joinReturnedValues(...) would just return the last given value. Furthermore, returnedValue would be the identity function.

    However, if you have a (more) precise domain you may want to collect all returned values. In this case the type of ReturnedValue could be Set[DomainValue].

    Called by the abstract interpreter when an exception is thrown that is not (guaranteed to be) handled within the same method.

    Note

    If the original exception value is null (/*E.g.*/throw null;), then the exception that is actually thrown is a new NullPointerException. This situation is, however, completely handled by OPAL and the exception value is hence never null.

  2. abstract def returnVoid(pc: PC): Computation[Nothing, (RecordReturnedValue.this)#ExceptionValue]

    Called when a return instruction with the given pc is reached.

    Called when a return instruction with the given pc is reached. In other words, when the method returns normally.
