org.eclipse.persistence.internal.libraries.asm.MethodVisitor
A visitor to visit a Java method. The methods of this class must be called in the following order: ( visitParameter )* [ visitAnnotationDefault ] ( visitAnnotation | visitTypeAnnotation | visitAttribute )* [ visitCode ( visitFrame | visitXInsn | visitLabel | visitInsnAnnotation | visitTryCatchBlock | visitTryCatchBlockAnnotation | visitLocalVariable | visitLocalVariableAnnotation | visitLineNumber )* visitMaxs ] visitEnd. In addition, the visitXInsn and visitLabel methods must be called in the sequential order of the bytecode instructions of the visited code, visitInsnAnnotation must be called after the annotated instruction, visitTryCatchBlock must be called before the labels passed as arguments have been visited, visitTryCatchBlockAnnotation must be called after the corresponding try catch block has been visited, and the visitLocalVariable, visitLocalVariableAnnotation and visitLineNumber methods must be called after the labels passed as arguments have been visited. @author Eric Bruneton
