Direct Known Subclasses:
PathMap.PathMapRoot
Enclosing class:
PathMap

public static class PathMap.PathMapNode extends Object
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

    Modifier and Type
    Method
    Description
    Create a new arc
    void
    Create a new arc to an existing target
    Get the arcs emanating from this node in the PathMap
    boolean
    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
    Ask whether the typed value (or string value) of the node reached by this path will be required.
    boolean
    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
    Indicate that the typed value or string value of the node reached by this path will be used.
    void
    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

  • Method Details

    • createArc

      public PathMap.PathMapNode createArc(AxisExpression step)
      Create a new arc
      Parameters:
      step - the AxisExpression representing this step
      Returns:
      the newly-constructed target of the new arc
    • createArc

      public void createArc(AxisExpression step, PathMap.PathMapNode target)
      Create a new arc to an existing target
      Parameters:
      step - the AxisExpression representing this step
      target - the target node of the new arc
    • getArcs

      public PathMap.PathMapArc[] getArcs()
      Get the arcs emanating from this node in the PathMap
      Returns:
      the arcs, each representing an AxisStep. The order of arcs in the array is undefined.
    • setReturnable

      public 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
      Parameters:
      returnable - true if the node represents a final result of the expression
    • isReturnable

      public 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
      Returns:
      true if the node represents a final result of the expression
    • setAtomized

      public void setAtomized()
      Indicate that the typed value or string value of the node reached by this path will be used.
    • isAtomized

      public boolean isAtomized()
      Ask whether the typed value (or string value) of the node reached by this path will be required.
      Returns:
      true if the typed value or string value of the node is required
    • setHasUnknownDependencies

      public 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
    • hasUnknownDependencies

      public 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
      Returns:
      true if the path has unknown dependencies
