  Overrides the super version.

  Overrides:
    `setRefid` in class `Resource`
  Parameters:
    `r` - the Reference to set.

### compareTo

    public int compareTo(java.lang.Object another)

  Specified by:
    `compareTo` in interface `java.lang.Comparable`
  Overrides:
    `compareTo` in class `Resource`
  Parameters:
    `another` - the other Resource against which to compare.
  Returns:
    a negative integer, zero, or a positive integer as this Resource is less than, equal to, or greater than the specified Resource.

### equals

    public boolean equals(java.lang.Object another)

  Compare another Object to this ArchiveResource for equality.

  Overrides:
    `equals` in class `Resource`

    String representatation of this Resource.

### checkEntry

    protected final void checkEntry()
                             throws BuildException

  Validate settings and ensure that the represented "archive entry" has been established.

  Throws:
    `BuildException`

### fetchEntry

    protected abstract void fetchEntry()

  Fetch information from the named entry inside the archive.

### dieOnCircularReference

    protected void dieOnCircularReference(java.util.Stack stk,
                                          Project p)

  Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).

  If one is included, throw a BuildException created by `circularReference`.

  This implementation is appropriate only for a DataType that cannot hold other DataTypes as children.

  The general contract of this method is that it shouldn't do anything if ``checked`` is true and set it to true on exit.

  Overrides:
    `dieOnCircularReference` in class `DataType`
  Parameters:
    `stk` - the stack of references to check.
    `p` - the project to use to dereference the references.
