Method Detail

shutDownImpl

protected void shutDownImpl()

Description copied from class: AbstractService

The implementation must overwrite this method if it has to release resources acquired during shutdown. Accoring to the contract of the IStartable interface of the CRT this method will be called only once. It will be called when the component is removed from the persistent configuration or when the system shuts down.

Overrides:

shutDownImpl in class AbstractService

startUpImpl

protected void startUpImpl()
                    throws ConfigurationException,
                           StartupException

This method is called by the framework when the WCM System is starting. The service implementation can perform initialization tasks here. Among other things the service could request instances of other components if it depends on them for it's initialization. The framework will detect cyclic dependencies during this start-up process and throw an exception.

Overrides:

startUpImpl in class AbstractService

Throws:

com.sapportals.wcm.WcmException - If the initialization of the service failed

ConfigurationException - Exception raised in failure situation

StartupException - Exception raised in failure situation

getAttachmentList

public IAttachmentList getAttachmentList(IResourceContext context,
                                         String id,
                                         boolean create)
                                  throws NoAttachmentListException

returns AttachmentList and may create one if it does not exist yet

Specified by:

getAttachmentList in interface IGlobalAttachment

Parameters:

id - id of Business Object (or anything else) for which Attachment shall be handled (might be null)

create - Shall AttachmentList be created

context - Resource Context

Returns:

IAttachmentList or null

Throws:

com.sapportals.wcm.WcmException

NoAttachmentListException

getAttachmentList

public IAttachmentList getAttachmentList(IResourceContext context,
                                         String id,
                                         boolean create,
                                         long lifetime)
                                  throws NoAttachmentListException

returns AttachmentList and may create one if it does not exist yet

Specified by:

getAttachmentList in interface IGlobalAttachment

Parameters:

id - id of Business Object (or anything else) for which Attachment shall be handled (might be null)

create - Shall AttachmentList be created

lifetime - lifetime of Attachments in millisecons (0 => never expires)

context - Resource Context

Returns:

IAttachmentList

Throws:

com.sapportals.wcm.WcmException

NoAttachmentListException

reconfigure

public void reconfigure(IConfiguration configuration)
                 throws ConfigurationException

Description copied from interface: IReconfigurable

Passes the new configuration data to the component. This method is called by the CRT whenever the configuration was changed.

Specified by:

reconfigure in interface IReconfigurable

Parameters:

configuration - The new configuration data.

Throws:

ConfigurationException - Exception raised in failure situation
