Constructor Detail

PathMap.PathMapNodeSet

public PathMap.PathMapNodeSet()

Create an initially-empty set of path map nodes

PathMap.PathMapNodeSet

public PathMap.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(AxisExpression step)

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

Parameters:

step - the AxisExpression 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

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
