    public void setRefid​(Reference r) throws BuildException
    Makes this instance in effect a reference to another FilterChain instance.

    Overrides:
      `setRefid` in class `DataType`
    Parameters:
      `r` - the reference to which this instance is associated
    Throws:
      `BuildException` - if this instance already has been configured.

  - ### add

    public void add​(ChainableReader filter)

  - ### dieOnCircularReference

    protected void dieOnCircularReference​(java.util.Stack<java.lang.Object> stk, Project p) throws BuildException
    Description copied from class: `DataType`
    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.
    Throws:
      `BuildException` - on error.
