Class OfflineInstrumentationAccessGenerator
java.lang.Object
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.

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 classclassname
- VM class nameprobecount
- probe count for this classmv
- code output
- Returns:
- additional stack size required by the implementation, including
the instance pushed to the stack
