public class Discovery_2_0_2_blob
extends Discovery

The Discovery class allows clients to discover resources registered in a catalogue, by providing four operations named query,present, describeRecordType, and getDomain. This class has a required association from the Catalogue Service class, and is thus always implemented by all Catalogue Service implementations. The Session class can be included with the Discovery class, in associations with the Catalogue Service class. The "e;query"e; and "e;present"e; operations may be executed in a session or stateful context. If a session context exists, the dynamic model uses internal states of the session and the allowed transitions between states. When the "e;query"e; and "e;present"e; state does not include a session between a server and a client, any memory or shared information between the client and the server may be based on private understandings or features available in the protocol binding. The describeRecordType and getDomain operations do not require a session context.

Discovery_2_0_2_blob

public Discovery_2_0_2_blob(WFService wfsService,
                            CatalogueConfiguration cswConfiguration)

Parameters:

wfsService - to contact

cswConfiguration - of this service

Method Detail

query

public GetRecordsResult query(GetRecords getRecords)
                       throws OGCWebServiceException

Performs a GetRecords request.

This involves the following steps:

• GetRecords->GetRecordsDocument
• GetRecordsDocument->GetFeatureDocument using XSLT
• GetFeatureDocument->GetFeature
• GetFeature request is performed against the underlying WFS
• WFS answers with a FeatureResult object (which contains a FeatureCollection)
• FeatureCollection-> GMLFeatureCollectionDocument (as a String)
• GMLFeatureCollectionDocument->GetRecordsResultDocument using XSLT
• GetRecordsResultDocument->GetRecordsResult

Overrides:

query in class Discovery

Parameters:

getRecords -

Returns:

GetRecordsResult

Throws:

OGCWebServiceException

query

public GetRecordByIdResult query(GetRecordById getRecordById)
                          throws OGCWebServiceException

Performs a GetRecordById request.

This involves the following steps:

• GetRecordById->GetRecordByIdDocument
• GetRecordByIdDocument->GetFeatureDocument using XSLT
• GetFeatureDocument->GetFeature
• GetFeature request is performed against the underlying WFS
• WFS answers with a FeatureResult object (which contains a FeatureCollection)
• FeatureCollection-> GMLFeatureCollectionDocument (as a String)
• GMLFeatureCollectionDocument->GetRecordsResultDocument using XSLT
• GetRecordsResultDocument->GetRecordsResult

Overrides:

query in class Discovery

Parameters:

getRecordById -

Returns:

The GetRecordByIdResult created from teh given GetRecordById

Throws:

OGCWebServiceException

guery

public GetRepositoryItemResponse guery(GetRepositoryItem request)
                                throws OGCWebServiceException

Contacts the wfsResource to find a rim:ExtrinsicObject which contains the GetRepositoryItem.getRepositoryItemID() and retrieves it's app:RegistryObject/app:extrinsicObject/app:ExtrinsicObject/app:object. The value in this property will then be written to the response stream (e.g. sent to the requester).

Overrides:

guery in class Discovery

Parameters:

request - the created OGCRequest

Returns:

the repository item response

Throws:

OGCWebServiceException
