public abstract class IdempotentExtensionWalker
extends ExtensionWalker

A ExtensionWalker which assures that each component is visited only once, making it easy to handle the fact that some components such as OperationModel, SourceModel, ConnectionProviderModel, etc, implement the flyweight pattern, which means that the same instance might be present at different levels.

The use of this walker makes it unnecessary to manually control if a given component has already been seen.

Method Detail

onSource

protected final void onSource(HasSourceModels owner,
                              SourceModel model)

Description copied from class: ExtensionWalker

Invoked when an SourceModel is found in the traversed extensionModel

Overrides:

onSource in class ExtensionWalker

Parameters:

owner - The component that owns the source

model - the SourceModel

onParameterGroup

protected void onParameterGroup(ParameterizedModel owner,
                                ParameterGroupModel model)

Description copied from class: ExtensionWalker

Invoked when an ParameterGroupModel is found in the traversed extensionModel

Overrides:

onParameterGroup in class ExtensionWalker

Parameters:

owner - The component that owns the source

model - the ParameterGroupModel

onParameter

protected void onParameter(ParameterizedModel owner,
                           ParameterGroupModel groupModel,
                           ParameterModel model)

Description copied from class: ExtensionWalker

Invoked when an ParameterModel is found in the traversed extensionModel

Overrides:

onParameter in class ExtensionWalker

Parameters:

owner - The component that owns the parameter

groupModel - the ParameterGroupModel in which the model is contained

model - the ParameterModel

onOperation

protected final void onOperation(HasOperationModels owner,
                                 OperationModel model)

Description copied from class: ExtensionWalker

Invoked when an OperationModel is found in the traversed extensionModel.

This method is also invoked when a ScopeModel or a RouterModel are found, if and only if the ExtensionWalker.onScope(HasOperationModels, ScopeModel) or ExtensionWalker.onRouter(HasOperationModels, RouterModel) methods were not overridden respectively.

Overrides:

onOperation in class ExtensionWalker

Parameters:

owner - The component that owns the operation

model - the OperationModel

onRouter

protected void onRouter(HasOperationModels owner,
                        RouterModel model)

Description copied from class: ExtensionWalker

Invoked when a RouterModel is found in the traversed extensionModel.

By default, this method simply delegates on ExtensionWalker.onOperation(HasOperationModels, OperationModel)

Overrides:

onRouter in class ExtensionWalker

Parameters:

owner - The component that owns the operation

model - the OperationModel

onScope

protected void onScope(HasOperationModels owner,
                       ScopeModel model)

Description copied from class: ExtensionWalker

Invoked when a ScopeModel is found in the traversed extensionModel.

By default, this method simply delegates on ExtensionWalker.onOperation(HasOperationModels, OperationModel)

Overrides:

onScope in class ExtensionWalker

Parameters:

owner - The component that owns the operation

model - the OperationModel

onConnectionProvider
