- org.jacoco.core.runtime.LoggerRuntime
-
- All Implemented Interfaces:
IExecutionDataAccessorGenerator
,IRuntime
public class LoggerRuntime extends AbstractRuntime
ThisIRuntime
implementation uses the Java logging API to report coverage data.The implementation uses a dedicated log channel. Instrumented classes call
Logger.log(Level, String, Object[])
with the class identifier in the first slot of the parameter array. The runtime implements aHandler
for this channel that puts the probe data structure into the first slot of the parameter array.

generateDataAccessor
public int generateDataAccessor(long classid, java.lang.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 aboolean[]
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.- 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
-
startup
public void startup(RuntimeData data) throws java.lang.Exception
Description copied from class:AbstractRuntime
Subclasses must call this method when overwriting it.- Specified by:
startup
in interfaceIRuntime
- Overrides:
startup
in classAbstractRuntime
- Parameters:
data
- the execution data for this runtime- Throws:
java.lang.Exception
- any internal problem during startup
-
shutdown
public void shutdown()
Description copied from interface:IRuntime
Allows the coverage runtime to cleanup internals. This class should be called when classes instrumented for this runtime are not used any more.
