OpenMaya deprecation system.
Macros to allow code to be selectively removed from the build based on deprecation criteria.
Here is a list of the currently supported deprecation flags. To build your plug-in to be compatible with deprecated functions removed just add the following defines to your compile flags:
Defined attributes:
Defined helper directives:
If you are building with a customized compiler that does not have a proper support it is safe to disable or edit this header file.
Help on Open Maya deprecation system ## To treat deprecation as an error, use the following compiler switch:
## To silence the deprecation warnings:
Define preprocessor macro _OPENMAYA_DEPRECATION_DISABLE_WARNING
Or use the following compiler switch:
