simplify
in classPattern
- Returns:
- the optimised Pattern
- Throws:
XPathException
-
setOriginalText
public void setOriginalText(java.lang.String pattern)

-
matches
public boolean matches(NodeInfo e, Context c) throws XPathException
Determine if the supplied node matches the pattern- Specified by:
matches
in classPattern
- Parameters:
e
- The NodeInfo representing the Element or other node to be tested against the Patternc
- The context in which the match is to take place. Only relevant if the pattern uses variables.- Returns:
- true if the node matches either of the operand patterns
- Throws:
XPathException
-
getNodeType
public short getNodeType()
Determine the types of nodes to which this pattern applies. Used for optimisation. For patterns that match nodes of several types, return Node.NODE- Overrides:
getNodeType
in classPattern
- Returns:
- the type of node matched by this pattern. e.g. Node.ELEMENT or Node.TEXT
-
