public class FloatArrayBuf_1
extends FloatArrayBuf

Class FloatArrayBuf_1 provides a buffer for an array of float items sent or received using the Message Protocol (MP). The array element stride must be 1. While an instance of class FloatArrayBuf may be constructed directly, normally you will use a factory method in class FloatBuf. See that class for further information.

Constructor Detail

FloatArrayBuf_1

public FloatArrayBuf_1(float[] theArray,
                       Range theRange)

Construct a new float array buffer.

Parameters:

theArray - Array.

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

Method Detail

get

public float 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 FloatArrayBuf

Parameters:

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

Returns:

Item at index i.

put

public void put(int i,
                float 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 FloatArrayBuf

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 FloatArrayBuf

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.
