SIObject

Object Hierarchy | Related C++ Class: SIObject

Introduced

v1.0

Description

SIObject exposes properties and methods that are supported by practically every object in the Softimage Object Model, such as the name of the object, its type and parent.

Some very basic Softimage objects do not support SIObject, for example GridData, SIVector3 and Image (see the Object Hierarchy for a complete list. For this reason some caution must be used to avoid assuming that all objects support SIObject.Name and SIObject.Type.

Examples

1. VBScript Example

'
'       This example outputs an object's properties
'
Option Explicit
MAIN()
sub main()
        On Error Resume Next
        ' Create the scene
        dim oObj
        set oObj = ActiveProject.ActiveScene.Root.AddGeometry("Sphere", "NurbsSurface")
        LogSIObject oObj

2. VBScript Example

' These objects all support SIObject
Application.LogMessage IsSIObject( ActiveSceneRoot )
Application.LogMessage IsSIObject( Dictionary.GetObject( "Camera" ) )
Application.LogMessage IsSIObject( CreateObject( "XSI.Application" ) )
Application.LogMessage IsSIObject( ActiveSceneRoot.AddNull() )
' A string cannot be accepted without conversion
Application.LogMessage IsSIObject( "Camera" )
' XSICollection and GridData do not support SIObject
Application.LogMessage IsSIObject( CreateObject( "XSI.Collection" ) )
Application.LogMessage IsSIObject( XSIFactory.CreateGridData )
function IsSIObject( in_obj )
        ' One way to test if an object supports
        ' SIObject is to call a method and see if
        ' there is a scripting error.
        ' Careful use of "on error resume next"
        ' prevents the entire script form halting
        dim strFullName
        on error resume next
        strFullName = in_obj.Fullname
        if ( err <> 0 ) then
                IsSIObject = false
        else
                IsSIObject = true       
        end if
        ' Turn error checking back on
        on error goto 0
end function
' The above example logs the following results:
'INFO : True
'INFO : True
'INFO : True
'INFO : True
'INFO : False
'INFO : False
'INFO : False
