Class LocalAspectManager

java.lang.Object
  ch.ethz.prose.LocalAspectManager

All Implemented Interfaces:: AspectManager, ch.ethz.prose.engine.ClassLoadListener

Direct Known Subclasses:: SecureLocalAspectManager

public class LocalAspectManager
extends java.lang.Object
implements AspectManager, ch.ethz.prose.engine.ClassLoadListener

Class LocalAspectManager extends AspectManager and implements a local extension manager. Upon creation, a LocalAspectManager registers itself as a listener of class load events into the current JoinPointManager.

Version:: $Revision: 1.1.1.1 $

Constructor Summary

protected LocalAspectManager(boolean isConnected, ch.ethz.jvmai.JVMAspectInterface ai)
          Create a new LocalAspectManager with no aspects inserted and create a JoinPointManager.

Method Summary

void abort(java.lang.Object txId)
          Abort the transaction txId.

void classLoaded(java.lang.Class newClass)
          This method is called every time a new class has been successfully loaded and prepared into the system.

void commit(java.lang.Object txId)
          Commit the transaction txId.

protected void createJoinPointManager(boolean isConnected, ch.ethz.jvmai.JVMAspectInterface ai)
          This Method is going to be overwritten from a subclass of LocalAspectManager that wants to register its own JoinPointManager.

void doInsertExtension(Aspect ext)
          Insert the extension ext into the extension manager.

void doWithdrawExtension(Aspect ext)
          Unregister the crosscuts belonging to ext from the corresponding JoinPointManager

protected void finalize()
          Remove all inserted extensions from this extension manager, disconnect the joinpoint manager from the JVMAI System and deconstruct it.

private void finishTransaction(java.lang.Object transactionId, int commitOrAbort)


java.util.List getAllAspects()
          Return the list of extensions currently inserted into the system.

ch.ethz.prose.engine.JoinPointManager getJoinPointManager()

private LocalAspectManager.TransactionGroup getTransactionGroup(java.lang.Object transactionId)


void insert(Aspect x)
          Insert the aspect asp into this AspectManager The insertion of the crosscuts belonging to the specified aspect is done in the proper order (first crosscut is registered as first).

void insert(Aspect x, java.lang.Object txId)
          Insert the aspect ext within the boundaries of the transaction txId.

boolean isConnectedToVM()
          Return the boolean status that indicates if this extension manager is connected to the VM through its joinpoint manager or if it is the test manager and has no connection to the VM.

private void prepareWithdrawExtension(Aspect ext, java.lang.Object transactionId)


private void registerCrosscuts(Aspect ext, java.lang.Class cls)


void startup()
          This method has to be called before an AspectManager is used.

void teardown()
          This method has to be called before an AspectManager is destroyed.

Constructor Detail

LocalAspectManager

protected LocalAspectManager(boolean isConnected,
                             ch.ethz.jvmai.JVMAspectInterface ai)

Create a new LocalAspectManager with no aspects inserted and create a JoinPointManager. register this extension manager as a class load listener of the current JoinPointManager.

Method Detail

createJoinPointManager

protected void createJoinPointManager(boolean isConnected,
                                      ch.ethz.jvmai.JVMAspectInterface ai)

This Method is going to be overwritten from a subclass of LocalAspectManager that wants to register its own JoinPointManager.

startup

public void startup()

This method has to be called before an AspectManager is used.

Specified by:: startup in interface AspectManager

teardown

public void teardown()

This method has to be called before an AspectManager is destroyed.

Specified by:: teardown in interface AspectManager

classLoaded

public void classLoaded(java.lang.Class newClass)

This method is called every time a new class has been successfully loaded and prepared into the system. It implements the functionality needed to update the extensions currently inserted into this extension to the current state of the system. For example, if a new class is loaded that contains join-points cross-cut by an existing crosscut E.C, the crosscut in question will be added as a listener of the JoinPointManager.

Specified by:: classLoaded in interface ch.ethz.prose.engine.ClassLoadListener

getTransactionGroup

prepareInsertExtension

private void prepareInsertExtension(Aspect ext,
                                    java.lang.Object transactionId)

private void prepareWithdrawExtension(Aspect ext,
                                      java.lang.Object transactionId)
