Method Detail

init

public void init(IControllerContext context,
                 Map<String,Object> attributes,
                 ProcessingComponentConfiguration... configurations)

Description copied from interface: IProcessingComponentManager

Called upon initialization of the Controller.

Specified by:

init in interface IProcessingComponentManager

Parameters:

context - controller context

attributes - global initialization attributes provided to the controller

configurations - component configurations provided to the controller

prepare

public IProcessingComponent prepare(Class<? extends IProcessingComponent> clazz,
                                    String id,
                                    Map<String,Object> inputAttributes,
                                    Map<String,Object> outputAttributes)

Description copied from interface: IProcessingComponentManager

Prepares a component for processing. Specific managers may simply instantiate a new component object, fetch a component from a pool or wrap a component prepared by a delegate manager etc.

Specified by:

prepare in interface IProcessingComponentManager

Parameters:

clazz - class of the component to prepare

id - Identifier of the component to prepare. May be null.

inputAttributes - input attributes for all components requested to perform processing. Both Init- and Processing-time attributes will be provided. Managers must not modify this map.

outputAttributes - storage for output attributes

recycle

public void recycle(IProcessingComponent component,
                    String id)

Description copied from interface: IProcessingComponentManager

Called after processing completed. This method is called regardless of whether the processing completed successfully or with an error.

Specified by:

recycle in interface IProcessingComponentManager

Parameters:

component - Component instance returned from IProcessingComponentManager.prepare(java.lang.Class, java.lang.String, java.util.Map, java.util.Map).

id - The same identifier of the component as used in the call to IProcessingComponentManager.prepare(java.lang.Class, java.lang.String, java.util.Map, java.util.Map). May be null.

dispose

public void dispose()

Description copied from interface: IProcessingComponentManager

Called upon disposal of the controller.

Specified by:

dispose in interface IProcessingComponentManager
