stringArrayIntersector [-allowDuplicates boolean] [-defineTemplate string] [-exists] [-intersect string[]] [-reset] [-useTemplate string] string

stringArrayIntersector is undoable, queryable, and editable.

The stringArrayIntersector command creates and edits an object which is able to efficiently intersect large string arrays. The intersector object maintains a sense of "the intersection so far", and updates the intersection when new string arrays are provided using the -i/intersect flag.

Note that the string intersector object may be deleted using the deleteUI command.

Return value

stringThe name of the intersector.

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


allowDuplicates, defineTemplate, exists, intersect, reset, useTemplate
Long name (short name) Argument types Properties
-exists(-ex) create
Returns true|false depending upon whether the specified object exists. Other flags are ignored.
-defineTemplate(-dt) string create
Puts a command in a mode where any other flags and args are parsed and added to the command template specified in the argument. They will be used as default arguments in any subsequent invocations of the command when templateName is set as the current template.
-useTemplate(-ut) string create
Force the command to use a command template other than the current one.
-allowDuplicates(-ad) boolean create
Should the intersector allow duplicates in the input arrays (true), or combine all duplicate entries into a single, unique entry (false). This flag must be used when initially creating the intersector. Default is 'false'.
-intersect(-i) string[] createedit
Intersect the specified string array with the current intersection being maintained by the intersector.
-reset(-r) edit
Reset the intersector to begin a new intersection.

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

MEL examples

// Create an intersector
string $myIntersector = `stringArrayIntersector`;

// Intersect some string arrays using the intersector
string $initialArray[] = {"Excellent", "Smithers", "doh"};
stringArrayIntersector -edit -intersect $initialArray $myIntersector;
stringArrayIntersector -edit -intersect {"Smithers", "Homer"} $myIntersector;

// Query the intersector to see what the intersection is so far
stringArrayIntersector -query $myIntersector;
// Result: Smithers //

// Reset the intersector so that you can use it again with new string
// arrays
stringArrayIntersector -edit -reset $myIntersector;

// Delete the intersector as we are now done with it
deleteUI $myIntersector;
