Class CoverageEnumerator

java.lang.Object

org.jetbrains.coverage.org.objectweb.asm.MethodVisitor

com.intellij.rt.coverage.instrumentation.CoverageEnumerator

All Implemented Interfaces:

org.jetbrains.coverage.org.objectweb.asm.Opcodes

Direct Known Subclasses:

CoverageEnumeratorWithInstructions

public class CoverageEnumerator
extends org.jetbrains.coverage.org.objectweb.asm.MethodVisitor
implements org.jetbrains.coverage.org.objectweb.asm.Opcodes

Collect information about coverage and prepare jumps and switches execution for coverage collection. This class uses MethodNode inside, so bytecode is firstly fully analysed and then written to a MethodWriter
