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 Details

field

protected Field field

value

protected 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 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.
