TGIS_CSProjCassini.TGIS_CSProjCassini() constructor

DK for Java | tatukgis.jdk.TGIS_CSProjCassini.Create | Constructors | Fields | Methods | Properties

Creates an instance of the projection object with WGS84 datum and initializes projection parameters from EPSG code or WKT string.

Available also on: Delphi | .NET | Python.

Overrides TGIS_CSProjAbstract.TGIS_CSProjAbstract().

// Java
public TGIS_CSProjCassini(
  int _epsg,
  java.lang.String _wkt
);

// Oxygene
public
  constructor (
    _epsg : Integer;
    _wkt : String
  ); override;

PURPOSE:Initialize projection instance with standard datum (WGS84) and coordinate system definition from EPSG or WKT sources.

BEHAVIOR:Sets Datum=WGS84 by default. If _epsg is provided, loads projection parameters from EPSG database. Otherwise parses WKT string to extract projection type and parameters. Validation errors stored in Error property.

USAGE:Direct instantiation is via subclasses. Framework typically creates instances via factory: TGIS_CSFactory.Create(epsg) returns correctly typed projection.

CONSTRAINTS:WGS84 is hardcoded default; use Datum property to change. EPSG lookup requires loaded EPSG database. Invalid EPSG codes or WKT fail gracefully, setting Error property.
