# ListClasses

Returns a list of object classes in a specified classifier. The action can also return the metadata associated with each object class and the labels of the images associated with each object class.

Type: synchronous

Parameter | Description | Required
--- | --- | ---
`classifier` | The name of the classifier that contains the object classes. | Yes
`imagelabels` | A Boolean value (default false) that specifies whether to return the labels of images associated with each object class. | No
`maxresults` | The maximum number of object classes to return in the response. | No
`metadata` | A Boolean value (default false) that specifies whether to return the metadata associated with each object class. | No
`start` | The starting point for the list when you set the `maxresults` parameter. For example, to start listing object classes from the tenth object class in the classifier, set `start=10`. The entries in the classifier are indexed from 1. | No

## Example

The following example lists up to 10 object classes contained in the `vehicles` classifier:

    /action=ListClasses&classifier=vehicles
                       &metadata=TRUE
                       &imagelabels=TRUE
                       &start=1
                       &maxresults=10

## Response

The response always includes the identifier of each object class that is returned, and the number of training images (`numimages`) that have been added to the class. The following example response also includes metadata and image labels:

    <autnresponse>
      <action>LISTCLASSES</action>
      <response>SUCCESS</response>
      <responsedata>
        <class>
          <identifier>cars</identifier>
          <numimages>30</numimages>
          <imagelabels>
            <imagelabel>car1</imagelabel>
            <imagelabel>car2</imagelabel>
            ...
          </imagelabels>
          <metadata>
            <item>
              <key>Name</key>
              <value>Value</value>
            </item>
            ...
          </metadata>
        </class>
        <class>
          <identifier>vans</identifier>
          <numimages>15</numimages>
          <imagelabels>
            <imagelabel>van1</imagelabel>
            <imagelabel>van2</imagelabel>
            <imagelabel>van3</imagelabel>
            ...
          </imagelabels>
        </class>
      </responsedata>
    </autnresponse>
