Interface ByteCodeElement

    • Method Detail

      • isVisibleTo

        boolean isVisibleTo​(TypeDescription typeDescription)

        Checks if this element is visible from a given type. Visibility is a wider criteria then accessibility which can be checked by isAccessibleTo(TypeDescription). Visibility allows the invocation of a method on itself or on external instances.

        Note: A method or field might define a signature that includes types that are not visible to a type. Such methods can be legally invoked from this type and can even be implemented as bridge methods by this type. It is however not legal to declare a method with invisible types in its signature that are not bridges what might require additional validation.

        Important: Virtual byte code elements, i.e. virtual methods, are only considered visible if the type they are invoked upon is visible to a given type. The visibility of such virtual members can therefore not be determined by only investigating the invoked method but requires an additional check of the target type.

        Parameters:
        typeDescription - The type which is checked for its visibility of this element.
        Returns:
        true if this element is visible for typeDescription.

      • isAccessibleTo

        boolean isAccessibleTo​(TypeDescription typeDescription)

        Checks if this element is accessible from a given type. Accessibility is a more narrow criteria then visibility which can be checked by isVisibleTo(TypeDescription). Accessibility allows the invocation of a method on external instances or on itself. Methods that can be invoked from within an instance might however not be considered accessible.

        Note: A method or field might define a signature that includes types that are not visible to a type. Such methods can be legally invoked from this type and can even be implemented as bridge methods by this type. It is however not legal to declare a method with invisible types in its signature that are not bridges what might require additional validation.

The visibility of such virtual members can therefore not be determined by only investigating the invoked method but requires an additional check of the target type.

        Parameters:
        typeDescription - The type which is checked for its accessibility of this element.
        Returns:
        true if this element is accessible for typeDescription.
