Class DirectoryTransformAdapter

java.lang.Object

oracle.jdeveloper.audit.transform.TransformAdapter

oracle.jdeveloper.audit.transform.DirectoryTransformAdapter

public class DirectoryTransformAdapter
extends TransformAdapter

Directory transform adapter for transforms of directories. Typically, such transforms create or delete files in directories, since directories themselves have little by way of interesting metadata.

createContext

protected TransformContext createContext(TransformContext.Shape shape,
                                         Transform transform,
                                         Violation violation,

Description copied from class: TransformAdapter

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

Specified by:

createContext in class TransformAdapter

isTransformable

public boolean isTransformable(ModelAdapter model)

Description copied from class: TransformAdapter

Gets whether a model is transformable by this transform adapter. The framework ensures the following before invoking this method:

• the calling thread holds a read lock on the model.

The default TransformAdapter implementation returns true if the model is writable or is version-controlled and can be made writable.

Overrides:

isTransformable in class TransformAdapter

Parameters:

model - The model to be be transformed.

makeTransformable

public java.lang.Boolean makeTransformable(TransformContext context)
                                    throws java.lang.Exception

Description copied from class: TransformAdapter

Makes a transform location transformable if not already so. 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 to which the transforms in the sequence apply.

  The default TransformAdapter implementation uses the VCSManager to check out the file containing the location if it is read-only and version controlled.

Overrides:

makeTransformable in class TransformAdapter

Parameters:

context - A transform context created by this adapter.

Returns:

whether the location is writable after checking out, or null if the location was already writable.

Throws:

java.lang.Exception

beginTransformSequence

public void beginTransformSequence(TransformSequenceContext sequenceContext)

Begins a transform sequence. A transform sequence is a sequence of transforms which use the same TransformAdapter subclass and are applied in sequence to the same model. The sequence context allows the transform adapters to share state through the sequence, typically to allow optimization (e.g., to coalesce multiple transactions into a single transaction). 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 to which the transforms in the sequence apply.

  The default TransformAdapter implementation does nothing.

  The DirectoryTransformAdapter implementation does nothing.

Overrides:

beginTransformSequence in class TransformAdapter

Parameters:

sequenceContext - The sequence context for the current sequence.

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 DirectoryTransformAdapter implementation does nothing.

Specified by:

beginTransform in class TransformAdapter

Parameters:

context - A transform context created by this adapter.

endTransform

public void endTransform(TransformContext context)

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 DirectoryTransformAdapter implementation does nothing.

Specified by:

endTransform in class TransformAdapter

Parameters:

context - A transform context created by this adapter.

cancelTransform

public void cancelTransform(TransformContext context)

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 DirectoryTransformAdapter implementation does nothing.

Specified by:

cancelTransform in class TransformAdapter

Parameters:

context - A transform context created by this type.

cancelTransformSequence

public void cancelTransformSequence(TransformSequenceContext sequenceContext)

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

• TransformAdapter.beginTransformSequence(oracle.jdeveloper.audit.transform.TransformSequenceContext) 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.endTransformSequence(oracle.jdeveloper.audit.transform.TransformSequenceContext) method has thrown an exception.

  The default TransformAdapter implementation does nothing.

  The DirectoryTransformAdapter implementation does nothing.

Overrides:

cancelTransformSequence in class TransformAdapter

Parameters:

sequenceContext - The sequence context for the current sequence.

endTransformSequence

public void endTransformSequence(TransformSequenceContext sequenceContext)

Ends a transform sequence. Before invoking this method, the framework ensures that TransformAdapter.beginTransformSequence(oracle.jdeveloper.audit.transform.TransformSequenceContext) has been invoked and its preconditions still hold.

The default TransformAdapter implementation does nothing.

The DirectoryTransformAdapter implementation does nothing.

Overrides:

endTransformSequence in class TransformAdapter

Parameters:

sequenceContext - The sequence context for the current sequence.
