#### checkEntry

    protected final void checkEntry()
                             throws BuildException

Throws:
  `BuildException`

#### fetchEntry

    protected abstract void fetchEntry()

Fetch information from the named entry inside the archive.

#### dieOnCircularReference

    protected void dieOnCircularReference(java.util.Stack<java.lang.Object> 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 `DataType.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.
