- ## Method Details

  - ### childNodes

    public Iterator childNodes()
    Returns an iterator over the child nodes of this GPathResult.
    Specified by:
      `childNodes` in class `GPathResult`
    Returns:
      an iterator over the child nodes of this GPathResult

  - ### iterator

    public Iterator iterator()
    Specified by:
      `iterator` in interface `Iterable`
    Specified by:
      `iterator` in class `GPathResult`

  - ### nodeIterator

    public Iterator nodeIterator()
    Returns the raw node iterator backing this lazy result.
    Specified by:
      `nodeIterator` in class `GPathResult`
    Returns:
      the underlying node iterator

  - ### parents

    public GPathResult parents()
    Throws a `GroovyRuntimeException`, because it is not implemented yet.
    Specified by:
      `parents` in class `GPathResult`
    Returns:
      the parents of this GPathResult

  - ### size

    public int size()
    Returns the size of this GPathResult.
    Specified by:
      `size` in class `GPathResult`
    Returns:
      the size of this GPathResult

  - ### text

    public String text()
    Returns the text of this GPathResult as a `String`.
    Specified by:
      `text` in class `GPathResult`
    Returns:
      the text of this GPathResult

  - ### find

    public GPathResult find(Closure closure)
    Returns the first child of this GPathResult matching the condition(s) specified in the passed closure.
    Specified by:
      `find` in class `GPathResult`
    Parameters:
      `closure` - a closure to filters the children of this GPathResult
    Returns:
      the first child matching the closure

  - ### findAll

    public GPathResult findAll(Closure closure)
    Returns the children of this GPathResult matching the condition(s) specified in the passed closure.
    Specified by:
      `findAll` in class `GPathResult`
    Parameters:
      `closure` - a closure to filters the children of this GPathResult
    Returns:
      the children matching the closure

  - ### build

    public void build(GroovyObject builder)
    Builds this object into the supplied builder.
    Parameters:
      `builder` - the target builder

  - ### writeTo

    public Writer writeTo(Writer out) throws IOException
    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 it 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.)

    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

  - ### replaceNode

    protected void replaceNode(Closure newValue)
    Lazily replaces the nodes represented by this result.
    Specified by:
      `replaceNode` in class `GPathResult`
    Parameters:
      `newValue` - closure generating the replacement content

  - ### replaceBody

    protected void replaceBody(Object newValue)
    Lazily replaces the body content represented by this result.
    Specified by:
      `replaceBody` in class `GPathResult`
    Parameters:
      `newValue` - replacement body content

  - ### appendNode

    protected void appendNode(Object newValue)
    Lazily appends content to the nodes represented by this result.
    Specified by:
      `appendNode` in class `GPathResult`
    Parameters:
      `newValue` - content to append
