[guide] $reference:

The $reference: uri (also $ref:) lets you read the current value of a project reference as a string. This uri is most useful in test scripts that need to create and examine project references. This uri’s handler is builtin into AntX; it is always available whenever you enable value URIs.

Parameters

The general form of the uri is: $ref[erence]:refid where refid is the project reference to be read.

Examples

1) The following snippet is part of a test script for the $newrefid: uri handler. It uses the $reference: uri to print the dynamically created references.

    <assign var="refid" value="${$newrefid:blah}"/>
    <echo message="New RefId: ${$var:refid|$reference:}"/>
    <assert isref="${$var:refid}" class="${String.class}"/>

    <datadef name="${$newrefid:blah?refid}"/>
       <fileset dir="${basedir}" includes="*.xml"/>
    </datadef>
    <echo message="New RefId: ${$var:refid|$reference:}"/>
    <assert isref="${$var:refid}" class="${Fileset.class}"/>
