Description copied from class: TransformAdapter

Creates a context for a transform over a violation at a location.

Specified by:

createContext in class TransformAdapter

beginTransform

public void beginTransform(TransformContext context)

Begins a transform of this type. The framework ensures the following before invoking this method:

• CommandProcessor.beginTrans(java.lang.String) has been invoked to start a command processor batch operation;
• the calling thread holds a read lock on the model containing the transform location;
• the TransformAdapter.beginTransformSequence(oracle.jdeveloper.audit.transform.TransformSequenceContext) method has been invoked;
• the transform class has an apply method that matches the construct at the violation location;
• if the transform class has an isApplicable method that matches the construct at the violation location, it has been invoked and has returned true;
• if the transform class has a query method that matches the construct at the violation location, it has been invoked and has returned non-null data.

  The TextTransformAdapter implementation of this method acquires and write locks the text buffer containing the text to transform.

Specified by:

beginTransform in class TransformAdapter

Parameters:

context -

createUndoableEditCommand

protected UndoableEditCommand createUndoableEditCommand(TextTransformContext context)

getBuffer

protected TextBuffer getBuffer()

endTransform

public void endTransform(TransformContext context)
                  throws java.lang.Exception

Ends a transform of this type. The framework ensures the following before invoking this method:

• TransformAdapter.beginTransform(oracle.jdeveloper.audit.transform.TransformContext) has been invoked (its preconditions still hold);
• the apply method that matches this construct has been invoked and has returned normally.

  The TextTransformAdapter implementation of this method creates an UndoableEditCommand for the edits, invokes it, and unlocks and releases the text buffer.

Specified by:

endTransform in class TransformAdapter

Parameters:

context - A transform context created by this adapter.

Throws:

java.lang.Exception

cancelTransform

public void cancelTransform(TransformContext context)
                     throws java.lang.Exception

Cancels a transform of this type. The framework ensures the following before invoking this method:

• TransformAdapter.beginTransform(oracle.jdeveloper.audit.transform.TransformContext) has been invoked (its preconditions still hold);
• the apply method that matches this construct has been invoked;
• the apply method has thrown an exception or the apply method has completed normally and the TransformAdapter.endTransform(oracle.jdeveloper.audit.transform.TransformContext) method has thrown an exception.

  The TextTransformAdapter implementation of this method unlocks and releases the text buffer.

Specified by:

cancelTransform in class TransformAdapter

Parameters:

context - A transform context created by this type.

Throws:

java.lang.Exception
