## org.apache.cocoon.stax.navigation
Class InSubtreeNavigator

    java.lang.Object
      org.apache.cocoon.stax.navigation.InSubtreeNavigator

All Implemented Interfaces:
  Navigator

    public final class InSubtreeNavigator

extends Object
implements Navigator

This `Navigator` implementation returns as long true as long it is in an opened clause. The navigator starts the moment an `XMLEvent` is a `StartElement` and matches all `Attribute`s and the name the `Navigator` is initialized with. The moment the corresponding `EndElement` is inserted the `Navigator` returns false. If the same element is contained nested more often the `Navigator` starts returning true the first element is inserted to the `Navigator.fulfillsCriteria(XMLEvent)` method till exactly this node is closed again with an `EndElement`.

      <anyElement> -> false
          <searchedElement> -> true
              <searchedElement> -> true
              <anyElement/> -> true
              </searchedElement> -> true
          </searchedElement> -> true
      </anyElement> -> false

Constructor Summary
`InSubtreeNavigator(String name)`
`InSubtreeNavigator(String name, Attribute... attributes)`
`InSubtreeNavigator(String name, List<Attribute> attributes)`

Method Summary
`boolean` | `fulfillsCriteria(XMLEvent event)` Depending on the `XMLEvent` it is returned if the navigator fulfills the criteria the `Navigator` is build for.
`MatchingType` | `getMatchingType()`
`boolean` | `isActive()` Every time the `Navigator.fulfillsCriteria(XMLEvent)` the value returned by this method is stored internally in the `Navigator`.
`void` | `setMatchingType(MatchingType matchingType)`

Method Detail

### fulfillsCriteria

    public boolean fulfillsCriteria(XMLEvent event)

  Depending on the `XMLEvent` it is returned if the navigator fulfills the criteria the `Navigator` is build for.

  Specified by:
    `fulfillsCriteria` in interface `Navigator`
  Parameters:
    `event` - of the XML analyzed at the moment.
  Returns:
    if the `XMLEvent` full fills all criteria of the `Navigator`.
  See Also:
    `Navigator.fulfillsCriteria(javax.xml.stream.events.XMLEvent)`

### isActive

    public boolean isActive()

  Every time the `Navigator.fulfillsCriteria(XMLEvent)` the value returned by this method is stored internally in the `Navigator`. As long as the `Navigator.fulfillsCriteria(XMLEvent)` method is not called again this method returns the last returned value of the `Navigator.fulfillsCriteria(XMLEvent)` method. As long the `Navigator.fulfillsCriteria(XMLEvent)` is not called false should be returned.

  Specified by:
    `isActive` in interface `Navigator`
  Returns:
    the actual value returned by the `Navigator.fulfillsCriteria(XMLEvent)` method.
  See Also:
    `Navigator.isActive()`

### getMatchingType

    public MatchingType getMatchingType()

### setMatchingType

    public void setMatchingType(MatchingType matchingType)
