Prints up the gml for a featurecollection.

Specified by:

handleFeatureCollection in interface FeatureCollectionIteration.Handler

Parameters:

collection - FeatureCollection being encoded

writeBounds

public void writeBounds(BoundingBox bounds)

writes the gml:boundedBy element to output based on fc.getBounds()

• FeatureTypeNamespaces as provided to the constructor

Specified by:

handleFeature in interface FeatureCollectionIteration.Handler

Parameters:

f - Feature being encoded
