io.delta.kernel.types.GeometryType

@Evolving
public final class GeometryType
extends DataType

The data type representing geometry values. A Geometry must have a fixed Spatial Reference System Identifier (SRID) that defines the coordinate system.

The SRID is specified as a string The engine is responsible for validating and interpreting the SRID value.

Since:

3.0.0

Constructor Details

GeometryType

public GeometryType(String srid)

Create a GeometryType with the specified SRID.

Parameters:

srid - the Spatial Reference System Identifier (any non-null, non-empty string)

Throws:

IllegalArgumentException - if the SRID is null or empty

Method Details

ofDefault

public static GeometryType ofDefault()

Returns a GeometryType with the default SRID.

ofSRID

public static GeometryType ofSRID(String srid)

Returns a GeometryType with the specified SRID.

Parameters:

srid - the Spatial Reference System Identifier (any non-null, non-empty string)

getSRID

public String getSRID()

Get the Spatial Reference System Identifier.

Returns:

the SRID string

isNested

public boolean isNested()

Description copied from class: DataType

Returns true iff this data is a nested data type (it logically parameterized by other types).

For example StructType, ArrayType, MapType are nested data types.

Specified by:
