## ResourceCount

Since Apache Ant 1.7

### Description

Display or set a property containing the size of a nested resource collection. Can also be used as a `condition`.

### Parameters

Attribute | Description | Required
--- | --- | ---
Task | Condition
property | The property to set. | No; by default, output value to the log | Ignored
refid | A reference to a resource collection. | Yes, unless a nested resource collection is supplied
count | Comparison count. | Ignored | Yes
when | Comparison type: equal, eq, greater, gt, less, lt, ge (greater or equal), ne (not equal), le (less or equal). | No; default is equal

### Parameters specified as nested elements

#### resource collection

A single resource collection should be specified via a nested element or the refid attribute.

### Examples

Store the number of resources in the specified filelist (two files) in the property named `count.foo`.

    <resourcecount property="count.foo">
      <filelist dir="." files="foo,bar"/>
    </resourcecount>

Store the number of lines of the current buildfile in the property `file.lines`. Requires Ant 1.7.1+ as `<concat>` has to be a resource.

    <project>
      <property name="file" value="${ant.file}"/>
      <resourcecount property="file.lines">
        <tokens>
          <concat>
            <filterchain>
              <tokenfilter>
                <linetokenizer/>
              </tokenfilter>
            </filterchain>
            <fileset file="${file}"/>
          </concat>
        </tokens>
      </resourcecount>
      <echo>The file '${file}' has ${file.lines} lines.</echo>
    </project>
