- ## Method Details

  - ### add

    public void add(ResourceComparator c)
    Add a delegate ResourceComparator.
    Parameters:
      `c` - the next delegate ResourceComparator.

  - ### equals

    public boolean equals(Object o)
    Equality method based on the vector of resources, or if a reference, the referred to object.
    Specified by:
      `equals` in interface `Comparator<Resource>`
    Overrides:
      `equals` in class `ResourceComparator`
    Parameters:
      `o` - the object to check against.
    Returns:
      true if there is equality.

  - ### hashCode

    public int hashCode()
    Hashcode based on the rules for equality.
    Overrides:
      `hashCode` in class `ResourceComparator`
    Returns:
      a hashcode.

  - ### resourceCompare

    protected int resourceCompare(Resource foo, Resource bar)
    Compare two Resources.
    Specified by:
      `resourceCompare` in class `ResourceComparator`
    Parameters:
      `foo` - the first Resource.
      `bar` - the second Resource.
    Returns:
      a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

  - ### dieOnCircularReference

    protected void dieOnCircularReference(Stack<Object> stk, Project p) throws BuildException
    Overrides the version from DataType to recurse on nested ResourceSelector s.
    Overrides:
      `dieOnCircularReference` in class `DataType`
    Parameters:
      `stk` - the Stack of references.
      `p` - the Project to resolve against.
    Throws:
      `BuildException` - on error.
