- com.databricks.jdbc.api.impl.converters.WKTConverter

```
public class WKTConverter
extends Object
```
Utility class for converting between WKT (Well-Known Text) and WKB (Well-Known Binary) formats.
This class uses the JTS (Java Topology Suite) library to provide robust WKT/WKB conversion functionality for geospatial data. JTS is a widely-used, well-tested library that implements the OpenGIS Consortium's Simple Features Specification for SQL.

  - toWKB
```
public static byte[] toWKB(String wkt)
                    throws DatabricksValidationException
```
    Converts WKT (Well-Known Text) to WKB (Well-Known Binary) format.
    This implementation uses the JTS library to parse the WKT string into a Geometry object and then converts it to WKB format using the custom OGC-compliant WKB writer.
    
    Parameters:
    
    wkt - the WKT string to convert
    
    Returns:
    
    the WKB representation as a byte array
    
    Throws:
    
    DatabricksValidationException - if the WKT is invalid
  - toWKT
```
public static String toWKT(byte[] wkb)
                    throws DatabricksValidationException
```
    Throws:
    
    DatabricksValidationException
  - extractSRIDFromEWKT
```
public static int extractSRIDFromEWKT(String ewkt)
```
    Extracts the SRID from an EWKT (Extended Well-Known Text) string.
    EWKT format includes SRID prefix: "SRID=4326;POINT(1 2)"
    
    Parameters:
    
    ewkt - the EWKT string
    
    Returns:
    
    the SRID value, or 0 if no SRID is specified
  - removeSRIDFromEWKT
```
public static String removeSRIDFromEWKT(String ewkt)
```
    Removes the SRID prefix from an EWKT string to get clean WKT.
    Converts "SRID=4326;POINT(1 2)" to "POINT(1 2)"
    
    Parameters:
    
    ewkt - the EWKT string
    
    Returns:
    
    the clean WKT string without SRID prefix
