Class SharedBooleanBuf

java.lang.Object

edu.rit.mp.Buf

edu.rit.mp.BooleanBuf

edu.rit.mp.buf.SharedBooleanBuf

public class SharedBooleanBuf
extends BooleanBuf

Class SharedBooleanBuf provides a buffer for a multiple thread safe Boolean item sent or received using the Message Protocol (MP). While an instance of class SharedBooleanBuf may be constructed directly, normally you will use a factory method in class BooleanBuf. See that class for further information.

Constructor Detail

SharedBooleanBuf

public SharedBooleanBuf(SharedBoolean item)

Construct a new shared Boolean buffer.

Parameters:

item - SharedBoolean object that wraps the item.

Method Detail

get

public boolean get(int i)

Obtain the given item from this buffer.

The get() method must not block the calling thread; if it does, all message I/O in MP will be blocked.

Specified by:

get in class BooleanBuf

Parameters:

i - Item index in the range 0 .. length()-1.

Returns:

Item at index i.

put

public void put(int i,
                boolean item)

Store the given item in this buffer.

The put() method must not block the calling thread; if it does, all message I/O in MP will be blocked.

Specified by:

put in class BooleanBuf

Parameters:

i - Item index in the range 0 .. length()-1.

item - Item to be stored at index i.

getReductionBuf

public Buf getReductionBuf(Op op)

Create a buffer for performing parallel reduction using the given binary operation. The results of the reduction are placed into this buffer.

Specified by:

getReductionBuf in class Buf

Parameters:

op - Binary operation.

Throws:

java.lang.ClassCastException - (unchecked exception) Thrown if this buffer's element data type and the given binary operation's argument data type are not the same.
