Field Detail

### fFieldActivator

    protected final FieldActivator fFieldActivator

  Field activator.

### fInitialDepth

    protected final int fInitialDepth

  Initial depth in the document at which this matcher was created.

### fElementDepth

    protected int fElementDepth

  Element depth.

### fMatchedDepth

    protected int fMatchedDepth

  Depth at match.

Constructor Detail

### Selector.Matcher

    public Selector.Matcher(Selector.XPath xpath,
                            FieldActivator activator,
                            int initialDepth)

  Constructs a selector matcher.

Method Detail

### startDocumentFragment

    public void startDocumentFragment()

  Description copied from class: `XPathMatcher`
  The start of the document fragment.

  Overrides:
    `startDocumentFragment` in class `XPathMatcher`

### startElement

    public void startElement(org.apache.xerces.xni.QName element,
                             org.apache.xerces.xni.XMLAttributes attributes)

  The start of an element. If the document specifies the start element by using an empty tag, then the startElement method will immediately be followed by the endElement method, with no intervening methods.

  Overrides:
    `startElement` in class `XPathMatcher`
  Parameters:
    `element` - The name of the element.
    `attributes` - The element attributes.

### endElement

    public void endElement(org.apache.xerces.xni.QName element,
                           org.apache.xerces.xs.XSTypeDefinition type,
                           boolean nillable,
                           java.lang.Object actualValue,
                           short valueType,
                           org.apache.xerces.xs.ShortList itemValueType)

  Overrides:
    `endElement` in class `XPathMatcher`
  Parameters:
    `element` - name of the element.
    `type` - content type of this element. IOW, the XML schema type of the `value`. Note that this may not be the type declared in the element declaration, but it is "the actual type". For example, if the XML is <foo xsi:type="xs:string">aaa</foo>, this parameter will be "xs:string".
    `nillable` - - nillable true if the element declaration is nillable.
    `actualValue` - - actual value the typed value of the content of this element.

### getIdentityConstraint

    public IdentityConstraint getIdentityConstraint()

  Returns the identity constraint.

### getInitialDepth

    public int getInitialDepth()

  get the initial depth at which this selector matched.
