Interface ISpatialReferenceFactory2

All Superinterfaces:

ISpatialReferenceFactory, Serializable

All Known Subinterfaces:

ISpatialReferenceFactory3, ISpatialReferenceFactory4

All Known Implementing Classes:

SpatialReferenceEnvironment

public interface ISpatialReferenceFactory2
extends ISpatialReferenceFactory, Serializable

Provides access to members that create different kinds of spatial reference components.

Superseded By

ISpatialReferenceFactory3

Description

ISpatialReferenceFactory2 extends the ISpatialReferenceFactory interface and provides methods for accessing a variety of predefined geographic (datum) transformations and creating any kind of spatial reference (PCS or GCS) from its factory code.

Remarks

The CreatePredefinedGeographicTransformations and the GetPredefinedGeographicTransformations methods both return an ISet of all the possible geotransformations that ArcObjects can create. The SpatialReferenceEnvironment maintains ownership of the set returned by GetPredefinedGeographicTransformations. Neither this set nor its elements should be modified. The Set and transformation elements returned by CreatePredefinedGeographicTransformations can be modified.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Method Summary

ISet	createPredefinedGeographicTransformations() Creates a list of predefined geographic transformations.
ISpatialReference	createSpatialReference(int srID) Creates a predefined spatial reference from an srID.
IGeoTransformationOperationSet	getGeoTransformationDefaults() Creates a list of default geographic transformations.
ISet	getPredefinedGeographicTransformations() Returns a list of predefined geographic transformations.

Method Detail

createPredefinedGeographicTransformations

ISet createPredefinedGeographicTransformations()
                                               throws IOException,
                                                      AutomationException

Creates a list of predefined geographic transformations.

Description

Returns a list of all predefined geographic (datum) transformations. The list has two columns: the factory code and the name.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Returns:

A reference to a com.esri.arcgis.system.ISet

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

createSpatialReference

ISpatialReference createSpatialReference(int srID)
                                         throws IOException,
                                                AutomationException

Creates a predefined spatial reference from an srID.

Description

Use a srID from the esriSRProjCSType or esriSRGeoCSType enumerations to create a particular predefined spatial reference.

Remarks

The CreateSpatialReference method creates a valid SpatialReference, either a projected or geographic coordinate system, depending on the supplied FactoryCode (here called an srID). The method returns an ISpatialReference. The example code illustrates how to test for what type of SpatialReference has been created. This method will raise an error (E_INVALIDARG) if the FactoryCode number supplied is not valid.

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Parameters:

srID - The srID (in)

Returns:

A reference to a com.esri.arcgis.geometry.ISpatialReference

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getGeoTransformationDefaults
