Method Detail

visitAnnotation

public AnnotationVisitor visitAnnotation(String desc,
                                boolean visible)

Prints a disassembled view of the given annotation.

Parameters:

desc - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

Returns:

a visitor to visit the annotation values.

visitAttribute

public void visitAttribute(Attribute attr)

Prints a disassembled view of the given attribute.

Parameters:

attr - an attribute.

visitEnd

public void visitEnd()

Does nothing.

createTraceAnnotationVisitor

protected TraceAnnotationVisitor createTraceAnnotationVisitor()

appendDescriptor

protected void appendDescriptor(int type,
                    String desc)

Appends an internal name, a type descriptor or a type signature to buf.

Parameters:

type - indicates if desc is an internal name, a field descriptor, a method descriptor, a class signature, ...

desc - an internal name, type descriptor, or type signature. May be null.
