Public Function IsValid As Boolean

public:
bool IsValid()

member IsValid : unit -> bool 

Return Value

Notes:

• It is not necessary to bind an OpenGL context to call this method.

• The buffer object will be invalid until memory is allocated, either explicitly (see OIV.Inventor.Devices.SoGLBufferObject.SetSize(System.UInt64)) or implicitly (e.g. mapping from another buffer).

• The buffer object will be invalid after calling OIV.Inventor.Devices.SoGLBufferObject.ClearInstance().
