示例1: readAsLongBuffer
import java.nio.LongBuffer; //導入方法依賴的package包/類
@Benchmark
public void readAsLongBuffer() throws IOException {
ByteBuffer byteBuffer = ByteBuffer.allocateDirect(64 * 1024);
LongBuffer longBuffer = byteBuffer.asLongBuffer();
long readValueCount = 0;
try (ReadableByteChannel byteChannel = _testFile.open();) {
while (byteChannel.read(byteBuffer) > 0) {
byteBuffer.flip();
while (longBuffer.hasRemaining()) {
long longValue = longBuffer.get();
assertThat(longValue).isEqualTo(readValueCount);
readValueCount++;
}
longBuffer.rewind();
}
