    - #### Attributes

          public Attributes(GPathResult parent,
                            String name,
                            String namespacePrefix,
                            Map<String,String> namespaceTagHints)

      Parameters:
        `parent` - the GPathResult prior to the application of the expression creating this GPathResult
        `name` - if the GPathResult corresponds to something with a name, e.g. a node
        `namespacePrefix` - the namespace prefix if any
        `namespaceTagHints` - the known tag to namespace mappings

    - #### Attributes

          public Attributes(GPathResult parent,
                            String name,
                            Map<String,String> namespaceTagHints)

      Parameters:
        `parent` - the GPathResult prior to the application of the expression creating this GPathResult
        `name` - if the GPathResult corresponds to something with a name, e.g. a node
        `namespaceTagHints` - the known tag to namespace mappings

  - ### Method Detail

    - #### name

          public String name()

      Description copied from class: `GPathResult`
      Returns the name of this GPathResult.
      Overrides:
        `name` in class `GPathResult`
      Returns:
        the name of this GPathResult

    - #### childNodes

          public Iterator childNodes()

      Throws a `GroovyRuntimeException`, because attributes can have no children.
      Overrides:
        `childNodes` in class `NodeChildren`
      Returns:
        an iterator over the child nodes of this GPathResult

    - #### iterator

          public Iterator iterator()

      Specified by:
        `iterator` in interface `Iterable`
      Overrides:
        `iterator` in class `NodeChildren`

    - #### nodeIterator

          public Iterator nodeIterator()

      Overrides:
        `nodeIterator` in class `NodeChildren`

    - #### parents

          public GPathResult parents()

      Description copied from class: `NodeChildren`
      Throws a `GroovyRuntimeException`, because it is not implemented yet.
      Overrides:
        `parents` in class `NodeChildren`
      Returns:
        the parents of this GPathResult

    - #### text

          public String text()

      Description copied from class: `GPathResult`
      Returns the text of this GPathResult as a `String`.
      Overrides:
        `text` in class `NodeChildren`

    - #### list

          public List list()

      Description copied from class: `GPathResult`
      Creates a list of objects representing this GPathResult.
      Overrides:
        `list` in class `GPathResult`
      Returns:
        a list representing of this GPathResult

    - #### findAll

          public GPathResult findAll(Closure closure)

      Description copied from class: `GPathResult`
      Returns the children of this GPathResult matching the condition(s) specified in the passed closure.
      Overrides:
        `findAll` in class `NodeChildren`
      Parameters:
        `closure` - a closure to filters the children of this GPathResult
      Returns:
        the children matching the closure

    - #### writeTo

          public Writer writeTo(Writer out)
                         throws IOException

      Description copied from interface: `Writable`
      Writes this object to the given writer.

      This is used to defer content creation until the point when it is streamed to the output destination. Oftentimes, content will be defined but not necessarily created (as is may be the case with a Closure definition.) In that case, the output is then 'deferred' to the point when it is serialized to the writer. This class may be used whenever an object should be responsible for creating its own textual representation, but creating the entire output as a single String would be inefficient (such as outputting a multi-gigabyte XML document.)

      Specified by:
        `writeTo` in interface `Writable`
      Overrides:
        `writeTo` in class `NodeChildren`
      Parameters:
        `out` - the Writer to which this Writable should output its data.
      Returns:
        the Writer that was passed
      Throws:
        `IOException` - if an error occurred while outputting data to the writer

    - #### build

          public void build(GroovyObject builder)

      Specified by:
        `build` in interface `Buildable`
      Overrides:
        `build` in class `NodeChildren`
