org.geotools.filter.expression
Class ToDirectPositionFunction
java.lang.Object
org.geotools.filter.expression.ToDirectPositionFunction
- All Implemented Interfaces:
- org.opengis.filter.expression.Expression, org.opengis.filter.expression.Function
public class ToDirectPositionFunction
- extends java.lang.Object
- implements org.opengis.filter.expression.Function
This function converts double values to DirectPosition geometry type. This is needed when the
data store doesn't have geometry type columns. This function expects:
- Literal: SRS_NAME (optional)
- Expression: expression of srs name if SRS_NAME is defined
- Expression: name of column pointing to first double value
- Expression: name of column pointing to second double value (optional, only for 2D)
