public interface ByteCodeElement
extends NamedElement.WithRuntimeName, ModifierReviewable, DeclaredByType, AnnotatedCodeElement

Implementations describe an element represented in byte code, i.e. a type, a field or a method or a constructor.

Field Detail

NON_GENERIC_SIGNATURE

static final String NON_GENERIC_SIGNATURE

The generic type signature of a non-generic byte code element.

Method Detail

getDescriptor

String getDescriptor()

Returns the descriptor of this byte code element.

Returns:

The descriptor of this byte code element.

getGenericSignature

String getGenericSignature()

Returns the generic signature of this byte code element. If this element does not reference generic types or references malformed generic types, null is returned as a signature.

Returns:

The generic signature or null if this element is not generic.

isVisibleTo

boolean isVisibleTo(TypeDescription typeDescription)

Checks if this element is visible from a given type.

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 access of this element.

Returns:

true if this element is visible for typeDescription.
