Synopsis

itemFilterAttr [-byName string] [-byNameString string] [-byScript string] [-classification string] [-dynamic boolean] [-exists] [-hasCurve boolean] [-hasDrivenKey boolean] [-hasExpression boolean] [-hidden boolean] [-intersect string string] [-keyable boolean] [-listBuiltInFilters] [-listOtherFilters] [-listUserFilters] [-negate boolean] [-parent string] [-published boolean] [-readable boolean] [-scaleRotateTranslate boolean] [-secondScript string] [-text string] [-union string string] [-writable boolean] [string]

itemFilterAttr is undoable, queryable, and editable.

Return value

In query mode, return type is based on queried flag.

Flags

Long name (short name)	Argument types	Properties
-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. This flag cannot be used in conjunction with the -byScript or -secondScript flags.
-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. This flag cannot be used in conjunction with the -byScript or -secondScript flags.
-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 ) This flag cannot be used in conjunction with the -byName or -byNameString flags.
-classification(-cls)	string
Indicates whether the filter is a built-in or user filter. The string argument must be either "builtIn" or "user". The "other" filter classification is deprecated. Use "user" instead. Filters created by Maya should be classified as "builtIn". Filters created by plugins or user scripts should be classified as "user". Filters will not be deleted by a file new. Filter nodes will be hidden from the UI (ex: Attribute Editor, Hypergraph etc) and will not be accessible from the command-line.
-dynamic(-dy)	boolean
The filter will only pass dynamic attributes
-exists(-ex)
The filter will only pass attributs that exist
-hasCurve(-hc)	boolean
The filter will only pass attributes that are driven by animation curves.
-hasDrivenKey(-hdk)	boolean
The filter will only pass attributes that are driven by driven keys
-hasExpression(-he)	boolean
The filter will only pass attributes that are driven by expressions
-hidden(-h)	boolean
The filter will only pass attributes that are hidden to the user
-intersect(-in)	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.
-keyable(-k)	boolean
The filter will only pass attributes that are keyable
-listBuiltInFilters(-lbf)
Returns an array of all attribute filters with classification "builtIn".
-listOtherFilters(-lof)
The "other" classification has been deprecated. Use "user" instead. Returns an array of all attribute filters with classification "other".
-listUserFilters(-luf)
Returns an array of all attribute filters with classification "user".
-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.
-published(-pub)	boolean
The filter will only pass attributes that are published on the container.
-readable(-r)	boolean
The filter will only pass attributes that are readable (outputs)
-scaleRotateTranslate(-srt)	boolean
The filter will show only SRT attributes: scale, rotate, translate and their children
-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. This flag cannot be used in conjunction with the -byName or -byNameString flags.
-text(-t)	string
Defines an annotation string to be stored with the filter
-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.
-writable(-w)	boolean
The filter will only pass attributes that are writable (inputs)

Flag can appear in Query mode of command	Flag can be used more than once in a command.

MEL examples

//    Create a filter that will pass all the SRT (scale-rotate-translate)
//    attributes.
//
string $srtFilter = `itemFilterAttr -scaleRotateTranslate true`;

//    Create a filter that will pass all the attributes driven by an
//    expression.
//
string $exprFilter = `itemFilterAttr -hasExpression true`;

//    Create a filter that will pass all the SRT attributes driven by an
//    expression (intersect two previous ones).
//
string $srtExprFilter = `itemFilterAttr -intersect $srtFilter $exprFilter`;

//    Delete the filters when done with them.
//
delete $srtFilter $exprFilter $srtExprFilter;
