getProviderName

java.lang.String getProviderName()

Returns the DataServerExplorer's name

Returns:

String containing this DataServerExplorer's name

canAdd

boolean canAdd()

Indicates whether this DataServerExplorer can create a new DataStore in the server.

Returns:

true if this DataServerExplorer can be created or false otherwise.

Indicates whether this DataServerExplorer can create a new DataStore in the server, given the store name.

Parameters:

storeName - store name.

Returns:

true if this DataServerExplorer can create a new store or false otherwise.

Throws:

DataException

list

java.util.List<DataStoreParameters> list()
                                  throws DataException

Provides a list of available stores in the server.

Returns:

list of DataStoreParameters

Throws:

DataException

get

DataStoreParameters get(java.lang.String name)
                 throws DataException

Throws:

DataException

exists

boolean exists(DataStoreParameters parameters)
        throws DataException
