Note: Strings representing object names and
arguments must be separated by commas. This is not depicted in the
synopsis.
itemFilterAttr is undoable, queryable, and editable.
This command creates a named itemFilterAttr object. This object can
be attached to editors, in order to filter the attributes going
through them. Using union and intersection filters, complex
composite filters can be created.
In query mode, return type is based on queried flag.

Long name (short name) |
Argument types |
Properties |
hidden(h) |
boolean |
   |
|
The filter will only pass attributes that are hidden to the
user |
|
writable(w) |
boolean |
   |
|
The filter will only pass attributes that are writable
(inputs) |
|
readable(r) |
boolean |
   |
|
The filter will only pass attributes that are readable
(outputs) |
|
keyable(k) |
boolean |
   |
|
The filter will only pass attributes that are keyable |
|
scaleRotateTranslate(srt) |
boolean |
   |
|
The filter will show only SRT attributes: scale, rotate,
translate and their children |
|
hasExpression(he) |
boolean |
   |
|
The filter will only pass attributes that are driven by
expressions |
|
hasDrivenKey(hdk) |
boolean |
   |
|
The filter will only pass attributes that are driven by driven
keys |
|
hasCurve(hc) |
boolean |
   |
|
The filter will only pass attributes that are driven by
animation curves. |
|
published(pub) |
boolean |
   |
|
The filter will only pass attributes that are published on the
container. |
|
byName(bn) |
string |
   |
|
The filter will only pass items whose names match the given
regular expression string. This string can contain the special
characters * and ?. '?' matches any one character, and '*' matches
any substring. |
|
byNameString(bns) |
string |
    |
|
The filter will only pass items whose names match the given
string. This is a multi-use flag which allows the user to specify
several strings. The filter will pass items that match any of the
strings. |
|
byScript(bs) |
string |
   |
|
The filter will run a MEL script named by the given string on
each attribute name. Attributes will pass the filter if the script
returns a non-zero value. The script name string must be the name
of a proc whose signature is:
global proc int procName( string $nodeName string $attrName
)
|
|
secondScript(ss) |
string |
   |
|
Can be used in conjunction with the -bs flag. The second script
is for filtering whole lists at once, rather than individually. Its
signature must be:
global proc string[] procName( string[] $nodeName string[]
$attrName )
It should take in a list of attributes, and return a filtered list
of attributes. |
|
union(un) |
[string, string] |
   |
|
The filter will consist of the union of two other filters,
whose names are the given strings. Attributes will pass this filter
if they pass at least one of the contained filters. |
|
intersect(intersect) |
[string, string] |
   |
|
The filter will consist of the intersection of two other
filters, whose names are the given strings. Attributes will pass
this filter if and only if they pass both of the contained
filters. |
|
negate(neg) |
boolean |
   |
|
This flag can be used to cause the filter to invert itself, and
reverse what passes and what fails. |
|
parent(p) |
string |
|
|
This flag is no longer supported. |
|
text(t) |
string |
   |
|
Defines an annotation string to be stored with the filter |
|
classification(cls) |
string |
   |
|
Internal use only. Indicates whether the filter is a built-in
or user filter. The string argument is one of "builtIn" | "user" |
"other". |
|
listBuiltInFilters(lbf) |
boolean |
 |
|
Returns an array of all attribute filters with classification
"builtIn". |
|
listUserFilters(luf) |
boolean |
 |
|
Returns an array of all attribute filters with classification
"user". |
|
listOtherFilters(lof) |
boolean |
 |
|
Returns an array of all attribute filters with classification
"other". |
|

command |
Flag can appear in Edit mode of command |
Flag can appear in Query mode of command |
Flag can have multiple arguments, passed
either as a tuple or a list. |
