public class Attributes extends NodeChildren
Lazy evaluated representation of a node's attributes.
  • Constructor Details

    • 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 Details

    • name

      public String name()
      Returns the selected attribute name without the leading @.
      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()
      Returns the raw node iterator backing this lazy result.
      Overrides:
      nodeIterator in class NodeChildren
      Returns:
      the underlying node iterator
    • parents

      public GPathResult parents()
      Throws a GroovyRuntimeException, because it is not implemented yet.
      Overrides:
      parents in class NodeChildren
      Returns:
      the parents of this GPathResult
    • text

      public String text()
      Returns the text of this GPathResult as a String.
      Overrides:
      text in class NodeChildren
      Returns:
      the text of this GPathResult
    • list

      public List list()
      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)
      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
      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.)

      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)
      Builds this object into the supplied builder.
      Specified by:
      build in interface Buildable
      Overrides:
      build in class NodeChildren
      Parameters:
      builder - the target builder
