Class GeometryEncoderSDE

java.lang.Object
  org.geotools.filter.GeometryEncoderSDE

All Implemented Interfaces:

FilterVisitor

public class GeometryEncoderSDE

extends java.lang.Object

implements FilterVisitor

Encodes the geometry related parts of a filter into a set of SeFilter objects and provides a method to get the resulting filters suitable to set up an SeQuery's spatial constraints.

Although not all filters support is coded yet, the strategy to filtering queries for ArcSDE datasources is separated in two parts, the SQL where clause construction, provided by SQLEncoderSDE and the spatial filters (or spatial constraints, in SDE vocabulary) provided here; mirroring the java SDE api approach
