# OcioModuleTransform

Abstract base class for a single OCIO transform entry in an OCIOModule.

Subclasses define the specific transform type (e.g. colour space, input, output, look)  
and override the default OCIO-related information displayed in OcioListWidget.

Base class (inherits properties and methods): _[Resource](/python-api/docs/resource#resource)_

Subclasses: _[OcioModuleColourSpaceTransform](/python-api/docs/ociomodulecolourspacetransform#ociomodulecolourspacetransform)_, _[OcioModuleInputTransform](/python-api/docs/ociomoduleinputtransform#ociomoduleinputtransform)_, _[OcioModuleLookTransform](/python-api/docs/ociomodulelooktransform#ociomodulelooktransform)_, _[OcioModuleLutTransform](/python-api/docs/ociomoduleluttransform#ociomoduleluttransform)_, _[OcioModuleNamedTransform](/python-api/docs/ociomodulenamedtransform#ociomodulenamedtransform)_, _[OcioModuleOutputTransform](/python-api/docs/ociomoduleoutputtransform#ociomoduleoutputtransform)_
