Method Details

simplify
Simplify the pattern: perform any context-independent optimisations- Overrides:
simplify
in classPattern
- Returns:
- the optimised Pattern
- Throws:
XPathException
-
analyze
Type-check the pattern. This is only needed for patterns that contain variable references or function calls.- Overrides:
analyze
in classPattern
- Returns:
- the optimised Pattern
- Throws:
XPathException
-
setOriginalText
Set the original text- Overrides:
setOriginalText
in classPattern
-
matches
Determine if the supplied node matches the pattern- Specified by:
matches
in classPattern
- Parameters:
e
- the node to be comparedcontext
- The dynamic context. Only relevant if the pattern uses variables, or contains calls on functions such as document() or key().- Returns:
- true if the node matches either of the operand patterns
- Throws:
XPathException
-
getNodeKind
public int getNodeKind()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:
getNodeKind
in classPattern
- Returns:
- the type of node matched by this pattern. e.g. Node.ELEMENT or Node.TEXT
-
getNodeTest
Get a NodeTest that all the nodes matching this pattern must satisfy- Specified by:
getNodeTest
in classPattern
-
getLHS
Get the LHS of the union -
getRHS
Get the RHS of the union -
setSystemId
Override method to set the system ID, so it's set on both halves- Overrides:
setSystemId
in classPattern
-
setLineNumber
public void setLineNumber(int lineNumber) Override method to set the system ID, so it's set on both halves- Overrides:
setLineNumber
in classPattern
