Storage Management(porttype)

This page describes the new portype offered by the SMS service.

StorageManagementCall

The use of the new port type has been simplified by a wrapper class (StorageManagementCall). The StorageManagementCall hide the WSRF implementation.

Functions

retrieveFilteredIOs

The method retrieveFilteredIOs retrieves all the IO selected by the specified filtering criteria. The filtering criteria are expressed through a list of SMSFilter.

The method returns a RS locator.

All filters applied in 'and' conjunction. The available filters:

• Property Filters, set of filters based on the properties values:
  • PropertyEqualFilter: accepts the IO with a property with the specified name and value.
  • PropertyBetweenLongFilter: accepts the IO if the specified property values is into the specified bounds.
• Reference Filters, set of filters based on IO references:
  • ReferenceSourceFilter: accepts the IO which is target in a reference with the specified IO.
  • ReferenceTargetFilter: accepts the IO which is target in a reference with the specified IO.

Example code:

//the filtering criteria
List<SMSFilter> filters = new LinkedList<SMSFilter>();
 
//a reference filter expressing the collection membership
ReferenceTargetFilter targetFilter = new ReferenceTargetFilter("contentmanagement:is-member-of", null, collectionID);
filters.add(targetFilter);
 
//a property filter based on IO creation time	
PropertyBetweenLongFilter creationTimeFilter = new PropertyBetweenLongFilter("contentmanagement:ObjectCreatedMillis", startTimestamp, endTimestamp);
filters.add(creationTimeFilter);
 
//we want back IO with content in attachment		
SMSResponseConfig responseConfig = InformationObjectResponse.plainInformationObjectWithContentInMessage();
 
String locator = call.retrieveFilteredIOs(responseConfig, filters);

Functions response

Some SMS methods returns an RS locator. The type of response can be configured through a SMSResponseConfig parameter.

The possible response configurations are:

• OIDResponse: the RS return strings representing the IOs id.
• InformationObjectResponse: the RS return InformationObjectDescriptions representing the IOs.

The InformationObjectResponse configuration accept some parameters to set how object are filled with IO informations. To help on setting the required parameters a set of static method have been created:

• plainInformationObject: only basic informations, name, type and IO, are returned
• plainInformationObjectWithProperties: basic informations and properties
• completeInformationObject: basic informations, properties and references, but not content
• completeInformationObjectWithContent: complete object information plus IO content. The location parameter specify where save the content.
• completeInformationObjectWithContentInMessage: complete object information plus IO content. The content is attached to the message.
• plainInformationObjectWithContent: basic object informations with the IO content in specified location.
• plainInformationObjectWithContentInMessage: basic object information with the IO content attached to the message.
