public class SoInputReader : SoDisposable

The SoInputReader type exposes the following members.

Public methodCanConvert

Returns true if the specified input source can be converted by this plugin.

Public methodConvert

Returns the specified input source in the form of an Open Inventor scene graph.

Public methodDispose
Releases all resources used by SoDisposable.
(Inherited from SoDisposable.)
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Public methodGetHashCode
Overrides GetHashCode().
(Inherited from SoNetBase.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public propertyIsDisposable
ISafeDisposable interface implementation.
(Inherited from SoDisposable.)

This class defines the base interface for loading a scene graph from an data format that is not directly supported by Open Inventor.

Input readers should be loaded and managed as plugins. Open Inventor automtically attempts to load all files that may be plugin libraries (files with the extension .dll or .so depending on the platform). Plugin libraries may also be explicitly loaded using OIV.Inventor.SoDB.AddPlugin(System.String). See more details on that page. The file name convention (not required) for readers is "Iv*Reader.dll (or .so)".

A plugin library must implement the initPlugin() and exitPlugin() C-formatted entry-points. The initPlugin() function is responsible for registering the new class (or classes) in the Open Inventor database through the standard SoType type creation mechanism. The exitPlugin() function is used to disable the use of the custom class(s) by removing the corresponding type(s) from the Open Inventor database.

When OIV.Inventor.SoDB.ReadAll(OIV.Inventor.SoInput) (for example) is called to create a scene graph from a file or buffer, Open Inventor first attempts to handle the data as .iv format. If that fails, Open Inventor will call the OIV.Inventor.SoInputReader.CanConvert(OIV.Inventor.SoInput) method for each loaded plugin class, that is derived from OIV.Inventor.SoInputReader, in the order they were loaded. The first reader plugin that returns true from this method will be used to handle the data.
