Method Detail

cover

public void cover(java.lang.String classSignature,
                  short methodIndex,
                  short markIndex)

Records a coverage of a marked bytecode instruction. This method should never throw an exception.

Specified by:

cover in interface IChannelLogger

Overrides:

cover in class DirectoryChannelLogger

Parameters:

classSignature - a signature of the class file being covered. this signature includes the fully-qualified name of the class, along with a checksum to uniquely identify it.

methodIndex - index for a method within the class. The meta-data store will know how to translate the index to a method signature.

markIndex - the index of the bytecode instruction mark for this particular channel.

run

public void run()

Called when the shutdown hook is called.

Specified by:

run in interface java.lang.Runnable

createObject

public java.lang.Object createObject(java.lang.Object key)

Called by the HashCache

Specified by:

createObject in interface HashCache.ObjectManager

Parameters:

key - the key associated with the created object.

Returns:

the newly created object

cleanUpObject

public void cleanUpObject(java.lang.Object key,
                          java.lang.Object obj)

Called by HashCache when the given object is being removed from the cache.

Specified by:

cleanUpObject in interface HashCache.ObjectManager

Parameters:

key - the key associated with the object.

obj - the object being cleaned up.

finalize

protected void finalize()
                 throws java.lang.Throwable

Throws:

java.lang.Throwable

addShutdownHook

protected void addShutdownHook()
