ObjectIdAggregatedStream

public ObjectIdAggregatedStream(AggregatedFileLogger aggregatedLogger,
                                TypeIdAggregatedStreamMap typeToId,
                                File outputDir)
                         throws IOException

Create an instance to record object types.

Parameters:

aggregatedLogger - destination logger object

typeToId - is an object to translate a type into an integer representing a type.

outputDir - location to save the object map

Throws:

IOException - when failed to save object map to outputDir

Method Detail

onNewObject

protected void onNewObject(Object o)

Register a type for each new object. This is separated from onNewObjectId because this method calls TypeIdMap.createTypeRecord that may call a ClassLoader's method. If the ClassLoader is also monitored by SELogger, the call indirectly creates another object ID.

Overrides:

onNewObject in class ObjectIdMap

Parameters:

o - is the object passed to the getId method.

onNewObjectId

protected void onNewObjectId(Object o,
                             long id)

Record an object ID and its Type ID in a file. In case of String and Throwable, this method also record their textual contents.

Overrides:

onNewObjectId in class ObjectIdMap

Parameters:

o - is the object passed to the getId method.

id - is the ID assigned to the object.

close

public void close()

Close the files written by this object.

Overrides:

close in class ObjectIdMap
