   org.geotools.data.store.DataFeatureCollection
      org.geotools.data.DefaultFeatureResults

All known Subclasses:   org.geotools.data.jdbc.JDBCFeatureCollection,
DefaultFeatureResults
public class DefaultFeatureResults extends DataFeatureCollection (Code)
Generic "results" of a query, class.

Please optimize this class when use with your own content. For example a "ResultSet" make a great cache for a JDBCDataStore, a temporary copy of an original file may work for shapefile etc.

Field Summary
protected  FeatureSourcefeatureSource
     Feature source used to aquire features, note we are only a "view" of this FeatureSource, its contents, transaction and events need to be forwarded through this collection api to simplier code such as renderers.
protected  Queryquery
    
protected  FeatureTypeschema
    
protected  MathTransformtransform
    

Constructor Summary
public  DefaultFeatureResults(FeatureSource source, Query query)
     FeatureResults query against featureSource.

Method Summary
protected  FeatureReaderboundsReader()
    
public  FeatureCollectioncollection()
    
public  ReferencedEnvelopegetBounds()
     Returns the bounding box of this FeatureResults

This implementation will generate the correct results from reader() if the provided FeatureSource does not provide an optimized result via FeatureSource.getBounds( Query ).

public  intgetCount()
     Number of Features in this query.
public  FeatureTypegetSchema()
     FeatureSchema for provided query.
protected  TransactiongetTransaction()
     Returns transaction from featureSource (if it is a FeatureStore), or Transaction.AUTO_COMMIT if it is not.
public  FeatureReaderreader()
    

Field Detail
featureSource
protected FeatureSource featureSource(Code)
Feature source used to aquire features, note we are only a "view" of this FeatureSource, its contents, transaction and events need to be forwarded through this collection api to simplier code such as renderers.



query
protected Query query(Code)
Query used to define this subset of features from the feature source



schema
protected FeatureType schema(Code)



transform
protected MathTransform transform(Code)




Constructor Detail
DefaultFeatureResults
public DefaultFeatureResults(FeatureSource source, Query query) throws IOException(Code)
FeatureResults query against featureSource.

Please note that is object will not be valid after the transaction has closed.

Really? I think it would be, it would just reflect the same query against the featuresource using AUTO_COMMIT.


Parameters:
  source -
Parameters:
  query -




Method Detail
boundsReader
protected FeatureReader boundsReader() throws IOException(Code)
Retrieve a FeatureReader for the geometry attributes only, designed for bounds computation



collection
public FeatureCollection collection() throws IOException(Code)



getBounds
public ReferencedEnvelope getBounds()(Code)
Returns the bounding box of this FeatureResults

This implementation will generate the correct results from reader() if the provided FeatureSource does not provide an optimized result via FeatureSource.getBounds( Query ).

If the feature has no geometry, then an empty envelope is returned.
throws:
  DataSourceException - See IOException
See Also:   org.geotools.data.FeatureResults.getBounds



getCount
public int getCount() throws IOException(Code)
Number of Features in this query.

This implementation will generate the correct results from reader() if the provided FeatureSource does not provide an optimized result via FeatureSource.getCount( Query ).


throws:
  IOException - If feature could not be read
throws:
  DataSourceException - See IOException
See Also:   org.geotools.data.FeatureResults.getCount



getSchema
public FeatureType getSchema()(Code)
FeatureSchema for provided query.

If query.retrieveAllProperties() is true the FeatureSource getSchema() will be returned.

If query.getPropertyNames() is used to limit the result of the Query a sub type will be returned based on FeatureSource.getSchema().

DOCUMENT ME!
throws:
  IOException - DOCUMENT ME!
throws:
  DataSourceException - DOCUMENT ME!



getTransaction
protected Transaction getTransaction()(Code)
Returns transaction from featureSource (if it is a FeatureStore), or Transaction.AUTO_COMMIT if it is not. Transacstion this FeatureResults opperates against



reader
public FeatureReader reader() throws IOException(Code)
Retrieve a FeatureReader for this Query FeatureReader for this Query
throws:
  IOException - If results could not be obtained
