java.lang.Object net.sf.saxon.expr.parser.PathMap.PathMapNode
public static class PathMap.PathMapNode
A node in the path map. A node holds a set of arcs, each representing a link to another node in the path map.
Method Summary | |
---|---|
boolean |
allPathsAreWithinStreamableSnapshot()
Determine whether the path is entirely within a streamable snapshot of a streamed document: that is, it must only navigate to ancestors and to attributes of ancestors |
PathMap.PathMapNode |
createArc(byte axis,
NodeTest test)
Create a new arc |
void |
createArc(byte axis,
NodeTest test,
PathMap.PathMapNode target)
Create a new arc to an existing target |
PathMap.PathMapArc[] |
getArcs()
Get the arcs emanating from this node in the PathMap |
boolean |
hasReachableReturnables()
Test whether there are any returnable nodes reachable from this node by zero or more arcs |
boolean |
hasUnknownDependencies()
Ask whether the path has unknown dependencies, typically because a node reached by the path is supplied as an argument to a user-defined function |
boolean |
isAtomized()
Ask whether the typed value (or string value) of the node reached by this path will be required. |
boolean |
isReturnable()
Ask whether the node represents a value that is returnable as the result of the supplied expression, rather than merely a node that is visited en route |
void |
setAtomized()
Indicate that the typed value or string value of the node reached by this path will be used. |
void |
setHasUnknownDependencies()
Indicate that the path has unknown dependencies, typically because a node reached by the path is supplied as an argument to a user-defined function |
void |
setReturnable(boolean returnable)
Indicate that the node represents a value that is returnable as the result of the supplied expression, rather than merely a node that is visited en route |
