retrieveAspectIds

public List<String> retrieveAspectIds(OwCMISNetwork network,
                                      OwCMISObjectClass clazz)
                               throws IOException,
                                      com.wewebu.ow.server.exceptions.OwException

Description copied from interface: OwCMISALAspectRetriever

Will return a list of Id's which must not conform with the Alfresco CMIS Id representation. The requester/caller must handle/check the id regarding it's needs.

Specified by:

retrieveAspectIds in interface OwCMISALAspectRetriever

Parameters:

network - OwCMISNetwork to get configuration

clazz - OwCMISObjectClass for which the list of mandatory aspect Id's should be retrieved.

Returns:

List of Strings representing the Id's

Throws:

IOException - If could not communicate with server (could not create connection)

com.wewebu.ow.server.exceptions.OwException - if could not retrieve configuration from network instance

getURL

protected URL getURL(OwCMISNetwork network,
                     String classId)
              throws MalformedURLException,
                     com.wewebu.ow.server.exceptions.OwException

Read connection URL from network configuration, if not available use RepositoryService WSDL definition and extract location depending on that setting.

Parameters:

network - OwCMISNetwork to read configuration

classId - String representing the OwObjectClass.getClassName() Id

Returns:

URL from where to retrieve Mandatory Aspect definition

Throws:

MalformedURLException - if URL could not be created/constructed

com.wewebu.ow.server.exceptions.OwException - problem retrieving configuration from network

getRequestTypeId

protected String getRequestTypeId(OwCMISNetwork network,
                                  String classId)

Transform the class Id into a representation which can be used for the service call. Will transform every "cmis:" specific namespace into the following types:

• cmis:document == cm:content
• cmis:folder == cm:folder
• cmis:* == cm:cmobject

In case of other namespace the leading prefix will be removed to represent native definition. At the end By default all colon (:) occurrence will be removed by an underscore (_) and the String returned.

Parameters:

network - OwCMISNetwork

classId - String

Returns:

String which should be used to request Aspect information

createAuthValue

protected String createAuthValue(OwCMISNetwork network)
                          throws com.wewebu.ow.server.exceptions.OwException

Create the Value for the HTTP "Authorization" header, which will be attached during retrieve REST-call.

Parameters:

network - OwCMISNetwork

Returns:

String representing the authorization information

Throws:

com.wewebu.ow.server.exceptions.OwException - if could not retrieve the credentials

processInputStream

protected List<String> processInputStream(InputStream stream,
                                          OwCMISNetwork network)
                                   throws IOException,
                                          com.wewebu.ow.server.exceptions.OwException

Process input stream and retrieve only the id's which are defined as "defaultAspects"

Parameters:

stream - InputStream from service call

network - OwCMISNetwork instance for localization or other information

Returns:

List of String's representing the Id's

Throws:

IOException - in case of error while reading input stream

com.wewebu.ow.server.exceptions.OwException - if parsing of service answer was not successful/ could not proceed
