方法详细资料

open

void open()
   throws java.io.IOException

Open the stream.

抛出:

java.io.IOException - if an I/O error occurs

openAsync

void openAsync(AsyncCompletionHandler<java.lang.Void> handler)

Open the stream asynchronously.

参数:

handler - the completion handler for opening the stream

write

void write(java.util.List<ByteBuf> buffers)
    throws java.io.IOException

Write each buffer in the list to the stream in order, blocking until all are completely written.

参数:

buffers - the buffers to write

抛出:

java.io.IOException - if there are problems writing to the stream

read

ByteBuf read(int numBytes)
      throws java.io.IOException

Read from the stream, blocking until the requested number of bytes have been read.

参数:

numBytes - The number of bytes to read into the returned byte buffer

返回:

a byte buffer filled with number of bytes requested

抛出:

java.io.IOException - if there are problems reading from the stream

writeAsync

void writeAsync(java.util.List<ByteBuf> buffers,
                AsyncCompletionHandler<java.lang.Void> handler)

Write each buffer in the list to the stream in order, asynchronously. This method should return immediately, and invoke the given callback on completion.

参数:

buffers - the buffers to write

handler - invoked when the read operation has completed

readAsync

void readAsync(int numBytes,
               AsyncCompletionHandler<ByteBuf> handler)

Read from the stream, asynchronously. This method should return immediately, and invoke the given callback when the number of requested bytes have been read.

参数:

numBytes - the number of bytes

handler - invoked when the read operation has completed

getAddress

ServerAddress getAddress()

The address that this stream is connected to.

返回:

the address

close

void close()

Closes the connection.

isClosed

boolean isClosed()

Returns the closed state of the connection

返回:

true if connection is closed
