Class SQLEncoderSDE

java.lang.Object
  org.geotools.filter.SQLEncoder
      org.geotools.filter.SQLEncoderSDE

All Implemented Interfaces:

FilterVisitor

public class SQLEncoderSDE

extends SQLEncoder

implements FilterVisitor

Encodes an attribute filter into a SQL WHERE statement for arcsde.

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 here and the spatial filters (or spatial constraints, in SDE vocabulary) provided by GeometryEncoderSDE; mirroring the java SDE api approach for easy programing
