Interface Repository

All Known Implementing Classes:

DefaultRepository, FeatureSourceRepository

public interface Repository

Provides a Repository of available FeatureTypes allowing Catalog metadata queries.

Currently GeoServer is providing requirements:

• Manage cross DataStore concepts (like Locks)
• Provide metadata information on FeatureType

Method Summary

java.util.Map	getDataStores() Access to the DataStores registed to this Catalog.
java.util.SortedMap	getFeatureSources() All FeatureSources by typeRef ( aka dataStoreId:typeName)
java.util.Set	getPrefixes() Retrieve Set of Namespaces prefixes registered by DataStores in this Catalog.
boolean	lockExists(java.lang.String lockID) Tests if a lock exists in this Catalog.
boolean	lockRefresh(java.lang.String lockID, Transaction transaction) Refresh feature lock as indicated by the WFS locking specification.
boolean	lockRelease(java.lang.String lockID, Transaction transaction) Release feature lock by lockID.
FeatureSource	source(java.lang.String dataStoreId, java.lang.String typeName) FeatureSoruce access.

Method Detail

getFeatureSources

public java.util.SortedMap getFeatureSources()

All FeatureSources by typeRef ( aka dataStoreId:typeName)

getPrefixes

public java.util.Set getPrefixes()
                          throws java.io.IOException

Retrieve Set of Namespaces prefixes registered by DataStores in this Catalog.

Namespace seems to be the gml prefix used when writing out GML. We may need to promote this to a "first class" object.

GeoServer maintains the following information in a NamespaceInfo object:

• prefix: uml prefix representing the namespace
• uri: uri used to reference namespace
• default: true if this is the "Default" namespace for the Catalog

GeoServer global.Data implements this interface. You may use the namespace strings returned by this method to look up NamespaceInfo objets by prefix.

Returns:

Set of available Namespace prefixes.

Throws:

java.io.IOException

source

public FeatureSource source(java.lang.String dataStoreId,
                            java.lang.String typeName)
                     throws java.io.IOException

FeatureSoruce access.

Parameters:

dataStoreId -

typeName -

Returns:

Throws:

java.io.IOException

getDataStores

public java.util.Map getDataStores()

Access to the DataStores registed to this Catalog.

Returns:

Map of registered dataStoreId:DataStore

lockRefresh

public boolean lockRefresh(java.lang.String lockID,
                           Transaction transaction)
                    throws java.io.IOException

Refresh feature lock as indicated by the WFS locking specification.

Refresh the indicated locks for each each DataStore managed by this Catalog.

Parameters:

lockID - Authorization identifing lock

transaction - Transaction with authorization for lock

Returns:

true if lock was found and refreshed

Throws:

java.io.IOException - If a problem occurs

lockRelease

public boolean lockRelease(java.lang.String lockID,
                           Transaction transaction)
                    throws java.io.IOException

Release feature lock by lockID.

Release the indicated locks for each each DataStore managed by this Catalog.

Parameters:

lockID - Authorization identifing lock

transaction - Transaction with authorization for lock

Returns:

true if lock was found and released

Throws:

java.io.IOException - If a problem occurs

lockExists

public boolean lockExists(java.lang.String lockID)

Tests if a lock exists in this Catalog.

This method will search all the DataStores to see if the indicated lock exists.

Parameters:

lockID - Authorization identifing lock

Returns:

true if lock was found
