Examples of org.aspectj.weaver.UnresolvedType

org.aspectj.weaver.UnresolvedType
A UnresolvedType represents a type to the weaver. UnresolvedTypes are resolved in some World (a type repository). When a UnresolvedType is resolved it turns into a ResolvedType which may be a primitive type, or a ReferenceType. ReferenceTypes may refer to simple, generic, parameterized or type-variable based reference types. A ReferenceType is backed by a delegate that provides information about the type based on some repository (for example an Eclipse based delegate, a bytecode based delegate or a reflection based delegate).
Every UnresolvedType has a signature, the unique key for the type in the world.


  public Member makeJoinPointSignatureForMethodInvocation(LazyClassGen cg, InvokeInstruction ii) {
    ConstantPool cpg = cg.getConstantPool();
    String name = ii.getName(cpg);
    String declaring = ii.getClassName(cpg);
    UnresolvedType declaringType = null;


    String signature = ii.getSignature(cpg);


    int modifier = (ii instanceof INVOKEINTERFACE) ? Modifier.INTERFACE
        : (ii.opcode == Constants.INVOKESTATIC) ? Modifier.STATIC : (ii.opcode == Constants.INVOKESPECIAL && !name
