Data:

Name	Description	Default value
name	object name	unnamed
printLog	if true, emits extra messages at runtime.	0
tags	list of the subsets the objet belongs to
bbox	this object bounding box
componentState	The state of the component among (Dirty, Valid, Undefined, Loading, Invalid).	Undefined
listening	if true, handle the events, otherwise ignore the events	0
tetrahedraMappedFromTetra	Each Tetrahedron of the input topology is mapped to the 8 tetrahedrons in which it can be divided
tetraSource	Which tetra from the input topology map to a given tetra in the output topology (sofa::InvalidID if none)
pointMappedFromPoint	Each point of the input topology is mapped to the same point
pointMappedFromEdge	Each edge of the input topology is mapped to his midpoint
pointSource	Which input topology element map to a given point in the output topology : 0 -> none, > 0 -> point index + 1, < 0 , - edge index -1

Links:

Name	Description
context	Graph Node containing this object (or BaseContext::getDefault() if no graph is used)
slaves	Sub-objects used internally by this object
master	nullptr for regular objects, or master object for which this object is one sub-objects
input	Input topology to map
output	Output topology to map
