public final class LapPath
extends Object

LapPath is used to describe path from the root of PoshPlan to some subnode of the plan. The path consists from several links, each link describes which cild of current node should be used to change into new current node. There are three major features we require: 1. Parse path from string 2. traverse plan according to the path and return the node. 3. serialize path to the string Examples of serialized path: /P:0/DC:0 - default plan, drive collection 0 /P:0/DC:0/S:1 - Drive collection 0, goal sense 1 /P:0/DC:0/DE:4 - fifth drive in the DC /P:0/DC:0/DE:4/S:0 - first trigger sense of fifth drive in the DC /P:0/DC:0/DE:4/A:0/AP:4 - reference to AP node.

Method Detail

traversePath

public PoshElement traversePath(PoshPlan plan)

Methods with name traverseXYZ mean traverse from XYZ below xyzLink means gor from xyz below according to type and id.

Parameters:

plan -

Returns:

Found node

Throws:

IllegalStateException - If path does not play nice with tree, e.g. when paths wants sense subnode in AP, but there is none according to syntax

IndexOutOfBoundsException - If some id on the path references to nonexistent node.

parse

public static LapPath parse(String serializedPath)
                     throws ParseException

Parse @serializedPath to

Parameters:

serializedPath - LapPath in serialized form, e.g. /P:0/DC:0/DE:1/S:1

Returns:

Path object created according to @serializedPath

Throws:

ParseException

append

public LapPath append(LapType type,
                      int id)

Create and return new LapPath by appending new link to all links of current path. This method does not change this path (LapPath is immutable)/
