public  void add(ResourceCollection r) 
{
                         
        if (rc != null) {
            throw new BuildException(ONE_NESTED_MESSAGE);
        }
        rc = r;
}

Add the ResourceCollection to count.

 public boolean eval() 
{
        if (rc == null) {
            throw new BuildException(ONE_NESTED_MESSAGE);
        }
        if (count == null) {
            throw new BuildException(COUNT_REQUIRED);
        }
        return when.evaluate(new Integer(rc.size()).compareTo(count));
}

Fulfill the condition contract.

 public  void execute() 
{
        if (rc == null) {
            throw new BuildException(ONE_NESTED_MESSAGE);
        }
        if (property == null) {
            log("resource count = " + rc.size());
        } else {
            getProject().setNewProperty(property, Integer.toString(rc.size()));
        }
}

Execute as a Task.

 public  void setCount(int c) 
{
        count = new Integer(c);
}

Set the target count number for use as a Condition.

 public  void setProperty(String p) 
{
        property = p;
}

Set the name of the property to set in task mode.

 public  void setRefid(Reference r) 
{
        Object o = r.getReferencedObject();
        if (!(o instanceof ResourceCollection)) {
            throw new BuildException(r.getRefId()
                + " doesn\'t denote a ResourceCollection");
        }
        add((ResourceCollection) o);
}

Set the ResourceCollection reference.

 public  void setWhen(Comparison c) 
{
        when = c;
}

Set the comparison for use as a Condition.
