public class FieldMatcher
extends PathMatcher

XPath matcher that tests one field of a key. This object is created by a FieldsMatcher when a SelectorMathcer finds a match to its selector. This object is responsible for finding a match to one field of the constraint. A field XPath may consist of "A|B|C". Each sub case A,B, and C is tested by a child FieldPathMatcher object. This class coordinates the work of those children and collects actual text that matches the given XPath.

Field Detail

field

protected Field field

value

protected java.lang.Object value

the matched value. If this field is null, then it means nothing is matched yet.

parent

protected final FieldsMatcher parent

parent FieldsMatcher object.

elementText

protected java.lang.StringBuffer elementText

this field is set to non-null if it's found that an element is matched to this XPath. This field is then used to collect the contents of the matched element until it encounters the endElement method.

children

protected Matcher[] children

child matchers.

Method Detail

onElementMatched

protected void onElementMatched(java.lang.String namespaceURI,
                    java.lang.String localName)
                         throws org.xml.sax.SAXException

this method is called when the element matches the XPath.

Specified by:

onElementMatched in class PathMatcher

Throws:

org.xml.sax.SAXException

onAttributeMatched

protected void onAttributeMatched(java.lang.String namespaceURI,
                      java.lang.String localName,
                      java.lang.String value,
                      org.relaxng.datatype.Datatype type)
                           throws org.xml.sax.SAXException

this method is called when the attribute matches the XPath.

Specified by:

onAttributeMatched in class PathMatcher

Throws:

org.xml.sax.SAXException

startElement

protected void startElement(java.lang.String namespaceURI,
                java.lang.String localName,
                org.xml.sax.Attributes attributes)
                     throws org.xml.sax.SAXException

Throws:

endElement

protected void endElement(org.relaxng.datatype.Datatype type)
                   throws org.xml.sax.SAXException

Throws:

org.xml.sax.SAXException

characters

protected void characters(char[] buf,
              int start,
              int len)
                   throws org.xml.sax.SAXException

Throws:

org.xml.sax.SAXException

getDepth

protected final int getDepth()

onRemoved

protected void onRemoved()
                  throws org.xml.sax.SAXException

called when this bundle is deactivated. This method is called by the endElement method when this bundle is removed. A derived class can override this method to do whatever necessary.

Throws:

org.xml.sax.SAXException
