<param>
<type>int</type>
<name>index</name>
<desc>Index of the component to be returned. This parameter is ignored if component is specified. Returns the id of the indicated component which can then be used to determine the count in a subsequent call to GetComponent.</desc>

<desc>Object of which to determine components. Can be <code>nil</code> in local calls. If definition is specified, this parameter is ignored.</desc>
