Java中的ByteBuffer asShortBuffer()方法
可以使用asShortBuffer()类java.nio.ByteBuffer中的方法将ByteBuffer的视图创建为ShortBuffer。此方法不需要任何参数，并且会根据需要返回一个短缓冲区。该缓冲区反映了对原始缓冲区所做的更改，反之亦然。
演示此的程序如下所示-
示例
import java.nio.*;
import java.util.*;
public class Demo {
public static void main(String[] args) {
int n = 50;
try {
ByteBuffer bufferB = ByteBuffer.allocate(n);
ShortBuffer bufferS = bufferB.asShortBuffer();
bufferS.put((short)5);
bufferS.put((short)9);
bufferS.put((short)2);
bufferS.put((short)8);
bufferS.put((short)3);
bufferS.rewind();
short s;
System.out.print("The ShortBuffer is: ");
while ((s = bufferS.get()) != 0) {
System.out.print(s + " ");
}
} catch (IllegalArgumentException e) {
System.out.println("Error!!! IllegalArgumentException");
} catch (ReadOnlyBufferException e){
System.out.println("Error!!! ReadOnlyBufferException");
}
}
}输出结果
The ShortBuffer is: 5 9 2 8 3
