com.databricks.jdbc.api.impl.AbstractDatabricksGeospatial

All Implemented Interfaces:

IDatabricksGeospatial

Direct Known Subclasses:

DatabricksGeography, DatabricksGeometry

public abstract class AbstractDatabricksGeospatial
extends Object
implements IDatabricksGeospatial

Abstract base class for geospatial data types in Databricks JDBC driver.

This class provides common functionality for both GEOMETRY and GEOGRAPHY types, including storage of WKT (Well-Known Text) format data and access to both WKT and WKB representations.

Constructor Detail

AbstractDatabricksGeospatial

protected AbstractDatabricksGeospatial(String wkt,
                                       int srid)
                                throws DatabricksValidationException

Constructs an AbstractDatabricksGeospatial with the specified WKT and SRID.

Parameters:

wkt - the Well-Known Text representation of the geospatial object

srid - the Spatial Reference System Identifier

Throws:

DatabricksValidationException - if the WKT is invalid
