public WFSFeatureSource.WFSFeatureResults(WFSFeatureSource fs,

Method Detail

getSchema

public FeatureType getSchema()

Description copied from interface: FeatureResults

Returns the FeatureType of the contents of this collection.

Please note that for a collection with a mixed contents the FeatureType may be degenerate (ie very generic). For many applications (like shapefiles or tables) the FeatureType can safely be used to describe all the Features in the result set.

Specified by:

getSchema in interface FeatureResults

Overrides:

getSchema in class DefaultFeatureResults

Returns:

DOCUMENT ME!

FeatureResults.getSchema()

reader

public FeatureReader reader()
                     throws java.io.IOException

Description copied from interface: FeatureResults

Provides access to the Features, please note that FeatureReader is a blocking api.

Specified by:

reader in interface FeatureResults

Overrides:

reader in class DefaultFeatureResults

Returns:

FeatureReader for this Query

Throws:

java.io.IOException - If results could not be obtained

See Also:

FeatureResults.reader()

getBounds

public com.vividsolutions.jts.geom.Envelope getBounds()

Description copied from interface: FeatureResults

Returns the bounding box of this FeatureResults.

This opperation may be expensive. Consider FeatureSource.getBounds( Query ) as an alternative.

This method is logically the same as:

 
 public Envelope getBounds() throws IOException {
     Envelope newBBox = new Envelope();
     Envelope internal;
     Feature feature;
 
     for (FeatureReader r = reader(); r.hasNext();) {
         feature = r.next();
         internal = feature.getDefaultGeometry().getEnvelopeInternal();
         newBBox.expandToInclude(internal);
     }
     return newBBox;  
 }
 
 

Specified by:

getBounds in interface FeatureResults

Overrides:

getBounds in class DefaultFeatureResults

Returns:

See Also:

FeatureResults.getBounds()

getCount

public int getCount()
             throws java.io.IOException

Description copied from interface: FeatureResults

Returns the number of Features in this FeatureResults.

This opperation may be expensive. Consider FeatureSource.getCount( Query ) as an alternative.

This method is logically the same as:

 
 public int getCount() throws IOException {
     int count = 0;
     for (FeatureReader r = reader(); r.hasNext(); count++) {
         r.next();
     }
     return count;  
 }
 
 

Specified by:

getCount in interface FeatureResults

Overrides:

getCount in class DefaultFeatureResults

Returns:

Throws:

java.io.IOException - If feature could not be read
