Class AllPTSet

java.lang.Object
  frysk.hpd.AllPTSet

All Implemented Interfaces:

PTSet

 class AllPTSet
extends Object
implements PTSet

AllPTSet holds all processes and their tasks and generates subsets for different types of sets.

boolean	containsTask(int procid, int taskid)
Proc	getProc(int procID)
ProcTasks[]	getSubset(ParseTreeNode[] parseTree) Generate a subset of this set, based on the tree generated by set notation parser.
ProcTasks[]	getSubsetByExec(String execname)
ProcTasks[]	getSubsetByState(int state)
Iterator	getTaskData()
Iterator	getTasks() Return an iterator to a collection of all the tasks.
void	removeProc(int procId) Remove a proc from the list
String	toString()
private int[]	walkRangeTree(ParseTreeNode node) Walks a tree that corresponds to a.b:c.d notation.
private int[]	walkRegTree(ParseTreeNode node) Walks a tree that corresponds to a:b.c:d notation, where b and d are optional ranges.

Method Detail

getProc

public Proc getProc(int procID)

containsTask

public boolean containsTask(int procid,
                            int taskid)

Specified by:

containsTask in interface PTSet

getTasks

public Iterator getTasks()

Return an iterator to a collection of all the tasks.

Specified by:

getTasks in interface PTSet

getTaskData

public Iterator getTaskData()

Specified by:

getTaskData in interface PTSet

removeProc

public void removeProc(int procId)

Remove a proc from the list

Specified by:

removeProc in interface PTSet

getSubset

public ProcTasks[] getSubset(ParseTreeNode[] parseTree)

Generate a subset of this set, based on the tree generated by set notation parser.

Parameters:

parseTree - tree generated by SetNotationParser, which is an array of ParseTreeNodes

getSubsetByState

public ProcTasks[] getSubsetByState(int state)

getSubsetByExec

public ProcTasks[] getSubsetByExec(String execname)

toString

public String toString()

Overrides:

toString in class Object

walkRangeTree

private int[] walkRangeTree(ParseTreeNode node)

Walks a tree that corresponds to a.b:c.d notation.

Parameters:

node - on a non-recursive call this should be a root of type ParseTreeNode.TYPE_RANGE

Returns:

array of {a,b,c,d} from notation a.b:c.d, -1 stands for a wildcard (*)

walkRegTree

private int[] walkRegTree(ParseTreeNode node)

Walks a tree that corresponds to a:b.c:d notation, where b and d are optional ranges.

Parameters:

node - on a non-recursive call this should be a root of type ParseTreeNode.TYPE_REG

Returns:

array of {a,b,c,d} from notation a:b.c:d, -1 stands for a wildcard (*)

addTasksFromRange

private void addTasksFromRange(ArrayList taskSets,
                               TreeMap proctasks,
                               int[] range)

Add tasks to the "tasks" ArrayList, as specified in "range", which corresponds to a.b:c.d notation

Parameters:

taskSets - array of arrays of tasks

proctasks - A treemap of Integer(procID) to ProcTasks

reg - an array of length 4 returned by walkRangeTree

addTasksFromReg

private void addTasksFromReg(ArrayList taskSets,
                             TreeMap proctasks,
                             int[] reg)

Add tasks to the "tasks" ArrayList, as specified in "reg", which corresponds to a:b.c:d notation

Parameters:

taskSets - array of arrays of tasks

proctasks - TreeMap of ProcTasks to put Procs and Tasks into

reg - an array of length 4 returned by walkRegTree
