Examples of com.alibaba.fastjson.asm.MethodVisitor

com.alibaba.fastjson.asm.MethodVisitor
A visitor to visit a Java method. The methods of this interface must be called in the following order: [ visitAnnotationDefault ] ( visitAnnotation | visitParameterAnnotation | visitAttribute )* [ visitCode ( visitFrame | visitXInsn | visitLabel | visitTryCatchBlock | visitLocalVariable | 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, visitTryCatchBlock must be called before the labels passed as arguments have been visited, and the visitLocalVariable and visitLineNumber methods must be called after the labels passed as arguments have been visited. @author Eric Bruneton
