Class CoverageClassAdapterExt

java.lang.Object
  org.objectweb.asm.ClassAdapter
      com.ikokoon.serenity.instrumentation.coverage.CoverageClassAdapterExt

All Implemented Interfaces:

org.objectweb.asm.ClassVisitor, org.objectweb.asm.Opcodes

public class CoverageClassAdapterExt
extends org.objectweb.asm.ClassAdapter
implements org.objectweb.asm.Opcodes

This is an alternative class for adding coverage instructions line by line. The process is as follows: 1) Add an array of integers the size of the lines in the class, to the class.
2) At each line increment the indexed line in the array.
3) Add a method to the class to retrieve the array of line counters.
4) At the end of the processing, i.e. when the JVM exist walk over the classes and accumulate all the data.
This method could possibly be faster, with less overhead in the actual class, but has not been fully implemented nor tested as of the writing as the original method for coverage is sufficient for current purposes.
