[detail level 1234]

CAL::usdmaya::fileio::AnimationCheckTransformAttributes	A utility class to provide static transform attributes for testing if a transform node is animated or not
CAL::usdmaya::fileio::AnimationTranslator	A utility class to help with exporting animated plugs from maya
▼CAL::usdmaya::cmds::BaseCallbackCommand	The base class for all commands that need to create/delete callbacks in some way. Fill m_callbacksToDelete with the CallbackIds you want to delete, and fill the m_callbacksToInsert array with the callbacks returned from AL::AL::event::EventScheduler::buildCallback. Within the undo/redo implementation of a mel command, simply call redoItImplementation. This method will destroy the callbacks requested, and insert the created callbacks. Once called, the values of the m_callbacksToDelete and m_callbacksToInsert will be swapped, therefore calling redoItImplementation again will undo the previous action
CAL::usdmaya::cmds::Callback	A command that allows you to create / delete callbacks assigned to a specific event within AL_usdmaya
CAL::usdmaya::cmds::DeleteCallbacks	A command that will delete all callback ids specified as an argument
Ccompare_MDagPath	Operator to compare MDagPaths with < operator

►CAL::usdmaya::fileio::translators::DagNodeTranslator	A class to transfer dag node data between Usd <–> Maya
CAL::usdmaya::fileio::translators::TransformTranslator	A utility class to transfer transform nodes between Maya and USD
CAL::usdmaya::nodes::DirtyOnlyIterator< WrappedIterator >	Iterator wrapper for LayerToIdsMap that hides non-dirty items Implemented as a template to define const / non-const iterator at same time
CAL::usdmaya::nodes::proxy::DrivenTransforms	This class maintains a set of prim paths to transform prims, and a cache of their matrix and visibility states. It also maintains a set of indices that describe the dirty states of those attributes that have been dirtied. If the number of transforms has changed, initTransforms should be called to initialise the internal memory storage. setDrivenPrimPaths should be called to specify the prim paths. Whenever you need to specify a change to the matrix or visibility values, call either dirtyVisibility or dirtyMatrix, and specify the index of the prim to modify. Within the compute method of the node, constructDrivenPrimsArray should be called to construct the array of prims to update, which can then be passed to the update method to set the dirty values on the prim attributes
CAL::usdmaya::fileio::Export	A class that wraps up the entire export process
CAL::usdmaya::fileio::ExporterParams	Parameters for the exporter. These parameters are constructed by any command or file translator that wishes to export data from maya, which are then passed to the AL::usdmaya::fileio::Export class to perform the actual export work

CAL::usdmaya::fileio::ImporterParams	Parameters for the importer
CAL::usdmaya::nodes::LayerDatabase	Stores layers, in a way that they may be looked up by the layer ref ptr, or by identifier Also, unlike boost::multi_index, we can have multiple identifiers per layer You can add non-dirty layers to the database, but the query operations will "hide" them - ie, iteration will skip by them, and findLayer will return an invalid ptr if it's not dirty We allow adding non-dirty items because if we want to guarantee we always have all the latest items, we need to deal with the situation where the current edit target starts out not dirty... and it's easiest to just add it then filter it if it's not dirty
