WriteBuffer

protected WriteBuffer(org.aoju.bus.core.io.segment.BufferPage bufferPage,
                      org.aoju.bus.socket.origin.Function<WriteBuffer,Void> flushFunction,
                      int writeQueueSize)

Method Detail

write

public void write(int b)
           throws IOException

按照OutputStream.write(int)规范：要写入的字节是参数 b 的八个低位 b 的 24 个高位将被忽略 而使用该接口时容易传入非byte范围内的数据,接口定义与实际使用出现歧义的可能性较大,故建议废弃该方法,选用writeByte(byte)

Specified by:

write in class OutputStream

Parameters:

b - byte

Throws:

IOException - 如果发生 I/O 错误

writeShort

public void writeShort(short v)
                throws IOException

Throws:

IOException

writeByte

public void writeByte(byte b)

writeInt

public void writeInt(int v)
              throws IOException

Throws:

IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Overrides:

write in class OutputStream

Throws:

IOException

writeAndFlush

public void writeAndFlush(byte[] b)
                   throws IOException

写入内容并刷新缓冲区 在Message.process(AioSession, Object)执行的write操作可无需调用该方法,业务执行完毕后框架本身会自动触发flush 调用该方法后数据会及时的输出到对端,如果再循环体中通过该方法往某个通道中写入数据将无法获得最佳性能表现,

Parameters:

b - 待输出数据

Throws:

IOException - 如果发生 I/O 错误

writeAndFlush

public void writeAndFlush(byte[] b,
                          int off,
                          int len)
                   throws IOException

Parameters:

b - 待输出数据

off - b的起始位点

len - 从b中输出的数据长度

Throws:

IOException - 如果发生 I/O 错误

flush

public void flush()

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class OutputStream

Throws:

IOException
