Class MDagPathUtil

source code

object --+
         |
        MDagPathUtil
Performs operations on MDagPaths which are hard or inconvenient to do otherwise

Note: We do NOT patch the actual api type as this would make it unusable to be passed in as reference/pointer type unless its being created by maya itself.

Method Details [hide private]

parentPath(cls, path)
Class Method

source code 
Returns:
MDagPath to the parent of path or None if path is in the scene root.

numShapes(cls, path)
Class Method

source code 
Returns:
return the number of shapes below path

childPathAtIndex(cls, path, index)
Class Method

source code 
Returns:
MDagPath pointing to this path's child at the given index

childPaths(cls, path, predicate=lambda x: True)
Class Method

source code 
Parameters:
  • predicate - returns True for each path which should be included in the result.
Returns:
list of child MDagPaths which have path as parent

pop(cls, path, num)
Class Method

source code 
Pop the given number of items off the end of the path
Returns:
path itself

extendToChild(cls, path, num)
Class Method

source code 
Extend path to the given child number - can be shape or transform
Returns:
path itself

childPathsByFn(cls, path, fn, predicate=lambda x: True)
Class Method

source code 
Get all children below path supporting the given MFn.type
Parameters:
  • fn - member of MFn
  • predicate - returns True for each path which should be included in the result.
Returns:
MDagPaths to all matched paths below this path

shapes(cls, path, predicate=lambda x: True)
Class Method

source code 
Parameters:
  • predicate - returns True for each path which should be included in the result.
Returns:
MDagPaths to all shapes below path

Note: have to explicitly assure we do not get transforms that are compatible to the shape function set for some reason - this is just odd and shouldn't be, but it happens if a transform has an instanced shape for example, perhaps even if it is not instanced

transforms(cls, path, predicate=lambda x: True)
Class Method

source code 
Parameters:
  • predicate - returns True to include path in result
Returns:
MDagPaths to all transforms below path
