Method Detail

canProcess

public boolean canProcess(Map<String,Serializable> params)

Are these parameters for us?

Specified by:

canProcess in interface DataAccessFactory

Parameters:

params - The full set of information needed to construct a live data source.

Returns:

booean true if and only if this factory can process the resource indicated by the param set and all the required params are pressent.

See Also:

DataAccessFactory.canProcess(java.util.Map)

createDataStore

public DataAccess<? extends FeatureType,? extends Feature> createDataStore(Map<String,Serializable> params)
                                                                    throws IOException

Create a SampleDataAccess.

Specified by:

createDataStore in interface DataAccessFactory

Parameters:

params - The full set of information needed to construct a live data store. Typical key values for the map include: url - location of a resource, used by file reading datasources. dbtype - the type of the database to connect to, e.g. postgis, mysql

Returns:

The created DataStore, this may be null if the required resource was not found or if insufficent parameters were given. Note that canProcess() should have returned false if the problem is to do with insuficent parameters.

Throws:

IOException - if there were any problems setting up (creating or connecting) the datasource.

See Also:

DataAccessFactory.createDataStore(java.util.Map)

getDescription

public String getDescription()

Need to implement this.

Specified by:

getDescription in interface DataAccessFactory

Returns:

A human readable description that is suitable for inclusion in a list of available datasources.

See Also:

DataAccessFactory.getDescription()

getDisplayName

public String getDisplayName()

Need to implement this.

Specified by:

getDisplayName in interface DataAccessFactory

Returns:

A short name suitable for display in a user interface.

See Also:

DataAccessFactory.getDisplayName()

getParametersInfo

public DataAccessFactory.Param[] getParametersInfo()

Need to implement this.

Specified by:

getParametersInfo in interface DataAccessFactory

Returns:

Param array describing the Map for createDataStore

See Also:

DataAccessFactory.getParametersInfo()

isAvailable

public boolean isAvailable()

Returns true, as this implementation is always available.

Specified by:

isAvailable in interface DataAccessFactory

Returns:

true if and only if this factory has all the appropriate jars on the classpath to create DataStores.

See Also:

DataAccessFactory.isAvailable()

getImplementationHints

public Map<RenderingHints.Key,?> getImplementationHints()

Returns an empty list, containing no hints.

Specified by:

getImplementationHints in interface Factory

Returns:

The map of hints, or an empty map if none.

See Also:

Factory.getImplementationHints()
