Method Details

matches
Determine if the supplied node matches the pattern- Specified by:
matches
in classPattern
- Parameters:
item
- 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
- if a dynamic error occurs during pattern matching
-
matchesBeneathAnchor
public boolean matchesBeneathAnchor(NodeInfo node, NodeInfo anchor, XPathContext context) throws XPathException Determine whether this pattern matches a given Node within the subtree rooted at a given anchor node. This method is used when the pattern is used for streaming.- Overrides:
matchesBeneathAnchor
in classPattern
- Parameters:
node
- The NodeInfo representing the Element or other node to be tested against the Patternanchor
- The anchor node, which must match any AnchorPattern subpatterncontext
- 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 the Pattern, false otherwise
- Throws:
XPathException
- if a dynamic error occurs during pattern matching
-
equals
Determine whether this pattern is the same as another pattern- Overrides:
equals
in classVennPattern
- Parameters:
other
- the other object
-
hashCode
