virtual AL_USDMAYA_PUBLIC bool	attributeHandled (const UsdAttribute &usdAttr)
	A temporary solution. Given a custom attribute, if a translator handles it somehow (i.e. lazy approach to not creating a schema), then overload this method and return true on the attribute you are handling. This will prevent the attribute from being imported/exported as a dynamic attribute. More...

AL_USDMAYA_PUBLIC MStatus AL::usdmaya::fileio::translators::TransformTranslator::copyAttributes	(	const UsdPrim &	from,
		MObject	to,
		const ImporterParams &	params
	)

helper method to copy attributes from the UsdPrim to the Maya node

Parameters

from	the UsdPrim to copy the data from
to	the maya node to copy the data to
params	the importer params to determine what to import

static AL_USDMAYA_PUBLIC MStatus AL::usdmaya::fileio::translators::TransformTranslator::copyAttributes	(	const MObject &	from,
		UsdPrim &	to,
		const ExporterParams &	params
	)

static

Copies data from the maya node onto the usd primitive.

Parameters

from	the maya node to copy the data from
to	the USD prim to copy the attributes to
params	the exporter params to determine what should be exported

static AL_USDMAYA_PUBLIC void AL::usdmaya::fileio::translators::TransformTranslator::copyAttributeValue	(	const MPlug &	attr,
		UsdAttribute &	usdAttr,
		const UsdTimeCode &	timeCode
	)

static

copy the attribute value from the plug specified, at the given time, and store the data on the usdAttr.

Parameters

attr	the attribute to be copied
usdAttr	the attribute to copy the data to
timeCode	the timecode to use when setting the data

AL_USDMAYA_PUBLIC MObject AL::usdmaya::fileio::translators::TransformTranslator::createNode	(	const UsdPrim &	from,
		MObject	parent,
		const char *	nodeType,
		const ImporterParams &	params
	)

overridevirtual

Creates a new maya node of the given type and set attributes based on input prim.

Parameters

from	the UsdPrim to copy the data from
parent	the parent Dag node to parent the newly created object under
nodeType	the maya node type to create
params	the importer params that determines what will be imported

static AL_USDMAYA_PUBLIC bool AL::usdmaya::fileio::translators::TransformTranslator::getAnimationVariables	(	TransformOperation	operation,
		MObject &	attribute,
		double &	conversionFactor
	)

static

retrieve the corresponding maya attribute for the transform operation.

Parameters

operation	the transform operation we want the maya attribute handle for
attribute	the returned attribute handle
conversionFactor	a scaling that should be applied to the maya attributes to put them into the correct units for USD

Returns: true if the attribute is known to be animated, and the attribute/conversionFactor contain valid results
