public class SharedUnsigned16BitIntegerArrayBuf_1
extends SharedUnsigned16BitIntegerArrayBuf

Class SharedUnsigned16BitIntegerArrayBuf_1 provides a buffer for a multiple thread safe array of unsigned 16-bit integer items sent or received using the Message Protocol (MP). The array element stride must be 1. While an instance of class SharedUnsigned16BitIntegerArrayBuf_1 may be constructed directly, normally you will use a factory method in class Unsigned16BitIntegerBuf. See that class for further information.

Constructor Detail

SharedUnsigned16BitIntegerArrayBuf_1

public SharedUnsigned16BitIntegerArrayBuf_1(SharedIntegerArray theArray,
                                            Range theRange)

Construct a new shared unsigned 16-bit integer array buffer.

Parameters:

theArray - Shared array.

theRange - Range of array elements to include in the buffer. The stride is assumed to be 1.

Method Detail

get

public int 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.

Overrides:

get in class SharedUnsigned16BitIntegerArrayBuf

Parameters:

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

Returns:

Item at index i.

put

public void put(int i,
                int 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.

Overrides:

put in class SharedUnsigned16BitIntegerArrayBuf

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.

Overrides:

getReductionBuf in class SharedUnsigned16BitIntegerArrayBuf

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.
