Interface JGraphAdapterBackend

All Known Implementing Classes:

JGraphSQLBackend

public interface JGraphAdapterBackend

TODO Support parent child relations and ports, but make it easy to ignore. We do not use an event-model for the backend since the calling of these methods is already based on an event information, and we use the commit / rollback to mimic transactional behaviour.

Method Summary

void	attributesChanged(JGraphAdapterModel sender, java.lang.Object cell, java.util.Map attributes, boolean validate)
void	cellRemoved(JGraphAdapterModel sender, java.lang.Object cell, boolean validate)
void	commit() Invoked after no exception has been thrown during a non-validating calling sequence on the backend.
void	edgeAdded(JGraphAdapterModel sender, java.lang.Object edge, java.lang.Object source, java.lang.Object target, boolean validate)
void	parentChanged(JGraphAdapterModel sender, java.lang.Object child, java.lang.Object parent, boolean validate)
void	rollback() Invoked when an exception has been thrown during a non-validating calling sequence on the backend.
void	sourceChanged(JGraphAdapterModel sender, java.lang.Object edge, java.lang.Object source, boolean validate)
void	targetChanged(JGraphAdapterModel sender, java.lang.Object edge, java.lang.Object target, boolean validate)
void	vertexAdded(JGraphAdapterModel sender, java.lang.Object vertex, boolean validate) Invoked when a vertex has been added to the sender model.

Method Detail

commit

void commit()
            throws java.lang.Exception

Invoked after no exception has been thrown during a non-validating calling sequence on the backend.

Throws:

java.lang.Exception

rollback

void rollback()
              throws java.lang.Exception

Invoked when an exception has been thrown during a non-validating calling sequence on the backend.

Throws:

java.lang.Exception

vertexAdded

void vertexAdded(JGraphAdapterModel sender,
                 java.lang.Object vertex,
                 boolean validate)
                 throws java.lang.Exception

Invoked when a vertex has been added to the sender model. If validate is true then the change should not be performed yet. If the validation or the actual change fail on the backend, you should throw an exception.

Throws:

java.lang.Exception

edgeAdded

void edgeAdded(JGraphAdapterModel sender,
               java.lang.Object edge,
               java.lang.Object source,
               java.lang.Object target,
               boolean validate)
               throws java.lang.Exception

Throws:

java.lang.Exception

cellRemoved

void cellRemoved(JGraphAdapterModel sender,
                 java.lang.Object cell,
                 boolean validate)
                 throws java.lang.Exception

Throws:

java.lang.Exception

parentChanged

void parentChanged(JGraphAdapterModel sender,
                   java.lang.Object child,
                   java.lang.Object parent,
                   boolean validate)
                   throws java.lang.Exception

Throws:

java.lang.Exception

sourceChanged

void sourceChanged(JGraphAdapterModel sender,
                   java.lang.Object edge,
                   java.lang.Object source,
                   boolean validate)
                   throws java.lang.Exception

Throws:

java.lang.Exception

targetChanged

void targetChanged(JGraphAdapterModel sender,
                   java.lang.Object edge,
                   java.lang.Object target,
                   boolean validate)
                   throws java.lang.Exception

Throws:

java.lang.Exception

attributesChanged

void attributesChanged(JGraphAdapterModel sender,
                       java.lang.Object cell,
                       java.util.Map attributes,
                       boolean validate)
                       throws java.lang.Exception

Throws:
