attrCompatibility(
[string [string]]
, [addAttr=boolean], [clear=boolean], [dumpTable=boolean], [enable=boolean], [nodeRename=string], [pluginNode=string], [removeAttr=boolean], [renameAttr=string], [type=string], [version=string])
Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.
attrCompatibility is undoable, NOT queryable, and NOT editable.
This command is used by Maya to handle compatibility issues between file format
versions by providing a mechanism to describe differences between two
versions. Plug-in writers can make use of this command to handle attribute
compatibility changes to files.
The first optional command argument argument is a node name and the
second optional command argument is an attribute name.
Warning: Only use this command to describe changes in names or
attributes of nodes that you have written as plugins. Do
not use this command to change information about builtin dependency
graph nodes.
Removing attributes on a plug-in node is a special case. Use a separate
attrCompatibility call with pluginNode flag and name so that these
attributes can be tracked even though the plug-in may not be loaded.

| Long name (short name) |
Argument types |
Properties |
addAttr(a)
|
boolean
|
|
|
Add the given attribute to the named node.
|
|
clear(clr)
|
boolean
|
|
|
Clear out the compatibility table.
This is only used internally for debugging purposes.
|
|
dumpTable(dmp)
|
boolean
|
|
|
Dump the current contents of the compatibility table.
This is only used internally for debugging purposes.
|
|
enable(e)
|
boolean
|
|
|
Enable or disable the compatibility table.
This is only used internally for debugging purposes.
|
|
nodeRename(nr)
|
string
|
|
|
Replace all uses of the node type 'nodeName' with given string.
|
|
renameAttr(r)
|
string
|
|
|
Rename the given attribute name of the given node with the
given string.
|
|
removeAttr(rm)
|
boolean
|
|
|
Remove the given attribute from the named node.
|
|
type(typ)
|
string
|
|
|
Change the type of the given attribute to the given type.
|
|
version(v)
|
string
|
|
|
Set the version target for subsequent commands to the given
string.
|
|
pluginNode(pn)
|
string
|
|
|
Registers the string argument as a plug-in node type. This is
necessary for subsequent attrCompatibility calls that
reference node attributes of unloaded plug-ins. Specifically, this
works in the case when attributes are being removed.
