Syntax
The IndexStream type exposes the following members.

Name | Description | |
---|---|---|
![]() | IsValidObject | Specifies whether the .NET object represents a valid Revit entity. |

Name | Description | |
---|---|---|
![]() | Dispose | Releases all resources used by the IndexStream |
![]() | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
![]() | GetHashCode | Serves as the default hash function. (Inherited from Object) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object) |

This base class cannot be used directly. Instead, a steam that is specific for each type of
primitive (point, line, or triangle) must be used.
- Use IndexStreamPoint to insert IndexPoint instances.
- Use IndexStreamLine to insert IndexLine instances.
- Use IndexStreamTriangle to insert IndexTriangle instances.
- Map the index buffer (see IndexBuffer).
- Get a stream for the appropriate primitive type from the buffer.
- Add sequences of indices corresponding to primitives of the same type to the stream. The indices will be written into the buffer that was used to create the stream.
- Unmap the buffer.
