Class PickleDataStore

java.lang.Object
  org.geotools.data.AbstractDataStore
      org.geotools.data.pickle.PickleDataStore

All Implemented Interfaces:

DataStore

public class PickleDataStore

extends AbstractDataStore

Pickel is really not very good, this is a simple wrap to let it live on as a zombie.

Any chance of people picking this up, adding index support to it and making it sing and dance? Please...

Method Detail

createSchema

public void createSchema(FeatureType featureType)
                  throws java.io.IOException

Description copied from class: AbstractDataStore

Subclass should implement to provide writing support.

Specified by:

createSchema in interface DataStore

Overrides:

createSchema in class AbstractDataStore

Parameters:

featureType - Requested FeatureType

Throws:

java.io.IOException

getTypeNames

public java.lang.String[] getTypeNames()

Description copied from class: AbstractDataStore

Convience method for retriving all the names from the Catalog Entires

Specified by:

getTypeNames in interface DataStore

Specified by:

getTypeNames in class AbstractDataStore

getSchema

public FeatureType getSchema(java.lang.String typeName)
                      throws java.io.IOException

Description copied from class: AbstractDataStore

Retrive schema information for typeName

Specified by:

getSchema in interface DataStore

Specified by:

getSchema in class AbstractDataStore

Throws:

java.io.IOException

getFeatureReader

protected FeatureReader getFeatureReader(java.lang.String typeName,
                                         Query query)
                                  throws java.io.IOException

Description copied from class: AbstractDataStore

GR: this method is called from inside getFeatureReader(Query ,Transaction ) to allow subclasses return an optimized FeatureReader wich supports the filter and attributes truncation specified in query

A subclass that supports the creation of such an optimized FeatureReader shold override this method. Otherwise, it just returns getFeatureReader(typeName)

Overrides:

getFeatureReader in class AbstractDataStore

Throws:

java.io.IOException

getFeatureReader

protected FeatureReader getFeatureReader(java.lang.String typeName)
                                  throws java.io.IOException

Description copied from class: AbstractDataStore

Subclass must implement.

Specified by:

getFeatureReader in class AbstractDataStore

Parameters:

typeName -

Returns:

FeatureReader over contents of typeName

Throws:

java.io.IOException

getFeatureWriter

protected FeatureWriter getFeatureWriter(java.lang.String typeName)
                                  throws java.io.IOException

Description copied from class: AbstractDataStore

Subclass can implement this to provide writing support.

Overrides:

getFeatureWriter in class AbstractDataStore

Parameters:

typeName -

Returns:

FeatureWriter over contents of typeName

Throws:

java.io.IOException - Subclass may throw IOException
