Class OfflineInstrumentationAccessGenerator

java.lang.Object
  extended by org.jacoco.core.runtime.OfflineInstrumentationAccessGenerator
All Implemented Interfaces:
IExecutionDataAccessorGenerator

public class OfflineInstrumentationAccessGenerator
extends Object
implements IExecutionDataAccessorGenerator

This implementation of IExecutionDataAccessorGenerator generate a direct dependency to the JaCoCo runtime agent to initialize the runtime and obtain probe arrays. This generator is designed for offline instrumentation only.

generateDataAccessor

public int generateDataAccessor(long classid,
                                String classname,
                                int probecount,
                                org.objectweb.asm.MethodVisitor mv)
Description copied from interface: IExecutionDataAccessorGenerator
This method generates the byte code required to obtain the coverage data structure for the class with the given id. Typically the instrumentation process will embed this code into a method that is called on class initialization. This method can be called at any time even outside the target VM. The generated code must push a boolean[] instance to the operand stack. Except this result object the generated code must not make any assumptions about the structure of the embedding method or class. The generated code must not use or allocate local variables.

Specified by:
generateDataAccessor in interface IExecutionDataAccessorGenerator
Parameters:
classid - identifier of the class
classname - VM class name
probecount - probe count for this class
mv - code output
Returns:
additional stack size required by the implementation, including the instance pushed to the stack
