public class UnionPattern extends Expression
| Constructor and Description |
|---|
UnionPattern() |
| Modifier and Type | Method and Description |
|---|---|
void |
callVisitors(ExpressionOwner owner,
XPathVisitor visitor)
This will traverse the heararchy, calling the visitor for
each member.
|
boolean |
canTraverseOutsideSubtree()
Tell if this expression or it's subexpressions can traverse outside
the current subtree.
|
boolean |
deepEquals(Expression expr)
Compare this object with another object and see
if they are equal, include the sub heararchy.
|
XObject |
execute(XPathContext xctxt)
Test a node to see if it matches any of the patterns in the union.
|
void |
fixupVariables(java.util.Vector vars,
int globalsSize)
No arguments to process, so this does nothing.
|
StepPattern[] |
getPatterns()
Get the contained step patterns to be tested.
|
void |
setPatterns(StepPattern[] patterns)
Set the contained step patterns to be tested.

fixupVariables in class Expressionvars - List of QNames that correspond to variables. This list
should be searched backwards for the first qualified name that
corresponds to the variable reference qname. The position of the
QName in the vector from the start of the vector will be its position
in the stack frame (but variables above the globalsTop value will need
to be offset to the current stack frame).
