  - ### Method Detail

    - #### add

          public void add(ResourceCollection rc)

      Adds a source.
      Parameters:
        `rc` - ResourceCollection

    - #### addFilterChain

          public final void addFilterChain(FilterChain filter)

      Adds a FilterChain.
      Parameters:
        `filter` - FilterChain

    - #### setEncoding

          public final void setEncoding(java.lang.String encoding)

      Encoding to use for input, defaults to the platform's default encoding.

      For a list of possible values see http://java.sun.com/j2se/1.5.0/docs/guide/intl/encoding.doc.html.

      Parameters:
        `encoding` - String

    - #### setRefid

          public void setRefid(Reference r)
                        throws BuildException

      Makes this instance in effect a reference to another ResourceList instance.
      Overrides:
        `setRefid` in class `DataType`
      Parameters:
        `r` - Reference
      Throws:
        `BuildException`

    - #### iterator

          public final java.util.Iterator<Resource> iterator()

      Fulfill the ResourceCollection contract. The Iterator returned will throw ConcurrentModificationExceptions if ResourceCollections are added to this container while the Iterator is in use.
      Specified by:
        `iterator` in interface `java.lang.Iterable<Resource>`
      Returns:
        a "fail-fast" Iterator.

    - #### size

      Fulfill the ResourceCollection contract.
      Specified by:
        `size` in interface `ResourceCollection`
      Returns:
        number of elements as int.

    - #### isFilesystemOnly

          public boolean isFilesystemOnly()

      Fulfill the ResourceCollection contract.
      Specified by:

                                                Project p)
                                         throws BuildException

      Overrides the version of DataType to recurse on all DataType child elements that may have been added.
      Overrides:

      Parameters:
        `stk` - the stack of data types to use (recursively).
        `p` - the project to use to dereference the references.
      Throws:
        `BuildException` - on error.
