java.lang.Object
  org.geotools.data.property.PropertyAttributeWriter

All Implemented Interfaces:

AttributeWriter

public class PropertyAttributeWriter

extends java.lang.Object

implements AttributeWriter

Simple AttributeWriter that produces Java properties files.

This AttributeWriter is part of the geotools2 DataStore tutorial, and should be considered a Toy.

The content produced witll start with the property "_" with the value being the typeSpec describing the featureType. Thereafter each line will represent a Features with FeatureID as the property and the attribtues as the value separated by | characters.
