Constructor Detail

TaskSet

public TaskSet()

Creates a new task set. The set is initially empty.

TaskSet

public TaskSet(int ntasks)

Creates a task set whose initial size is large enough to explicitly represent tasks with indices in the range 0 through ntasks-1. All tasks are initially false.

Parameters:

ntasks - the initial size of the task set.

Throws:

java.lang.NegativeArraySizeException - if the specified initial size is negative.

TaskSet

public TaskSet(int ntasks,
               java.lang.String str)

Construct a TaskSet and initialize from a hex string representation.

Parameters:

nbits - number of tasks in the TaskSet

str - hex string representation of tasks in the TaskSet

Throws:

java.lang.NegativeArraySizeException - if the specified initial size is negative.

Method Detail

clear

public void clear(int[] indices)
           throws java.lang.IndexOutOfBoundsException

Clear the bits at each position given by the array of indices

Parameters:

indexes - array of indices to clear

Throws:

java.lang.IndexOutOfBoundsException

clone

public java.lang.Object clone()

Overrides:

clone in class java.util.BitSet

copy

public TaskSet copy()

Create a copy of the TaskSet

Returns:

a copy of the TaskSet

set

public void set(int[] indices)
         throws java.lang.IndexOutOfBoundsException

Set the tasks at each position given by the array of indices

Parameters:

indices - array of indices to clear

Throws:

java.lang.IndexOutOfBoundsException

toArray

public int[] toArray()

Convert the TaskSet to an array containing the indices of all tasks. If there are no tasks, an empty array is returned.

Returns:

array containing the indices of all set bits.

toHexString

public java.lang.String toHexString()

Convert the TaskSet into a hex string representation. The number of characters in the string is always even.

Returns:

hex string representation of TaskSet

toString

public java.lang.String toString()

Overrides:

toString in class java.util.BitSet

taskSize

public int taskSize()

Get the fixed number of tasks represented by the TaskSet. This differs from BitSet.size() which is the number of bits of space used by the TaskSet and BitSet.length() which is the index of the highest bit plus one.

Returns:

initial number of bits
