MFnNumericData Class Reference

#include <MFnNumericData.h>

Class Description

Numeric data function set.

MFnNumericData allows the creation and manipulation of numeric data objects for use in the dependency graph. Normally, data objects are not required for the transmission of numeric data. The graph supports numeric types directly (see the methods of MDataHandle).

Numeric data objects are useful if you have an attribute that accepts generic data. A generic attribute can accept multiple types of data, so you cannot hardwire it to accept a specific type of numeric data. So, generic attributes can only accept numeric data in the form of actual data objects.

This function set only supports numeric data with multiple components, such as a pair of floats or a triple of integers. Single numeric values can be retrieved directly using MPlug or MDataHandle.
