Class ModifiedASMAnalyzer

java.lang.Object

org.objectweb.asm.tree.analysis.Analyzer

org.apache.flink.api.java.sca.ModifiedASMAnalyzer

All Implemented Interfaces:

org.objectweb.asm.Opcodes

@Internal
public class ModifiedASMAnalyzer
extends org.objectweb.asm.tree.analysis.Analyzer

Modified version of ASMs Analyzer. It defines a custom ASM Frame and allows jump modification which is necessary for UDFs with one iterable input e.g. GroupReduce. (see also UdfAnalyzer's field "iteratorTrueAssumptionApplied")
