Constructor Detail

PathMapNodeSet

public PathMapNodeSet()

Create an initially-empty set of path map nodes

PathMapNodeSet

public PathMapNodeSet(PathMap.PathMapNode singleton)

Create a set of path map nodes that initially contains a single node

Parameters:

singleton - the single node to act as the initial content

Method Detail

createArc

public PathMap.PathMapNodeSet createArc(byte axis,
                                        NodeTest test)

Create an arc from each node in this node set to a corresponding newly-created target node

Parameters:

axis - the axis of the step defining the transition

test - the node test of the step defining the transition

Returns:

the set of new target nodes

addNodeSet

public void addNodeSet(PathMap.PathMapNodeSet nodes)

Combine two node sets into one

Parameters:

nodes - the set of nodes to be added to this set

setAtomized

public void setAtomized()

Set the atomized property on all nodes in this nodeset

setReturnable

public void setReturnable(boolean isReturned)

Set the returnable property on all nodes in this nodeset

hasReachableReturnables

public boolean hasReachableReturnables()

Test whether there are any returnable nodes reachable from nodes in this nodeset

allPathsAreWithinStreamableSnapshot

public 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

addDescendants

public void addDescendants()

Indicate that all the descendants of the nodes in this nodeset are required

setHasUnknownDependencies

public void setHasUnknownDependencies()

Indicate that all the nodes have unknown dependencies
