| Constructor Summary | |
| public | Path(Step[] steps)
|
| areBasicPredicates | | protected boolean areBasicPredicates(Expression predicates)(Code) | | |
| computeContextDependent | | public boolean computeContextDependent()(Code) | | |
| createContextForStep | | protected EvalContext createContextForStep(EvalContext context, int axis, NodeTest nodeTest)(Code) | | Different axes are serviced by different contexts. This method
allocates the right context for the supplied step.
|
| evalSteps | | protected EvalContext evalSteps(EvalContext context)(Code) | | Given a root context, walks a path therefrom and builds a context
that contains all nodes matching the path.
|
| getSingleNodePointerForSteps | | protected Pointer getSingleNodePointerForSteps(EvalContext context)(Code) | | Given a root context, walks a path therefrom and finds the
pointer to the first element matching the path.
|
| isSimplePath | | public boolean isSimplePath()(Code) | | Recognized paths formatted as foo/bar[3]/baz[@name = 'biz']
. The evaluation of such "simple" paths is optimized and
streamlined.
|
| isSimpleStep | | protected boolean isSimpleStep(Step step)(Code) | | A Step is "simple" if it takes one of these forms: ".", "/foo",
"@bar", "/foo[3]". If there are predicates, they should be
context independent for the step to still be considered simple.
