Class NestedMethodAnalyzer

java.lang.Object

org.apache.flink.shaded.asm5.org.objectweb.asm.tree.analysis.Interpreter

org.apache.flink.shaded.asm5.org.objectweb.asm.tree.analysis.BasicInterpreter

org.apache.flink.api.java.sca.NestedMethodAnalyzer

All Implemented Interfaces:

org.apache.flink.shaded.asm5.org.objectweb.asm.Opcodes

@Internal
public class NestedMethodAnalyzer
extends org.apache.flink.shaded.asm5.org.objectweb.asm.tree.analysis.BasicInterpreter

Extends ASM's BasicInterpreter. Instead of ASM's BasicValues, it introduces TaggedValues which extend BasicValue and allows for appending interesting information to values. The NestedMethodAnalyzer follows interesting values and analyzes nested methods (control/method flow) if necessary.
