Class TransportWriter

java.lang.Object
  org.simpleframework.transport.TransportWriter

All Implemented Interfaces:

ByteWriter

public class TransportWriter
extends Object
implements ByteWriter

The TransportWriter object is used to write bytes to and underlying transport. This is essentially an adapter between an OutputStream and the underlying transport. Each byte array segment written to the underlying transport is wrapped in a bytes buffer so that it can be sent by the transport layer.

Constructor Detail

TransportWriter

public TransportWriter(Transport transport)

Constructor for the TransportWriter object. This is used to create an adapter for the transport such that a byte array can be used to write bytes to the array.

Parameters:

transport - the underlying transport to write bytes to

Method Detail

write

public void write(byte[] array)
           throws IOException

This method is used to deliver the provided array of bytes to the underlying transport. Depending on the connection type the array may be encoded for SSL transport or write directly. Any implementation may choose to buffer the bytes for performance.

Specified by:

write in interface ByteWriter

Parameters:

array - this is the array of bytes to write to the client

Throws:

IOException

write

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

This method is used to deliver the provided array of bytes to the underlying transport. Depending on the connection type the array may be encoded for SSL transport or write directly. Any implementation may choose to buffer the bytes for performance.

Specified by:

write in interface ByteWriter

Parameters:

array - this is the array of bytes to write to the client

off - this is the offset within the array to write from

len - this is the number of bytes that are to be sent

Throws:

IOException

write

public void write(ByteBuffer buffer)
           throws IOException

This method is used to deliver the provided buffer of bytes to the underlying transport. Depending on the connection type the array may be encoded for SSL transport or write directly. Any implementation may choose to buffer the bytes for performance.

Specified by:

write in interface ByteWriter

Parameters:

buffer - this is the buffer of bytes to write to the client

Throws:

IOException

write

public void write(ByteBuffer buffer,
                  int off,
                  int len)
           throws IOException

This method is used to deliver the provided buffer of bytes to the underlying transport. Depending on the connection type the array may be encoded for SSL transport or write directly. Any implementation may choose to buffer the bytes for performance.

Specified by:

write in interface ByteWriter

Parameters:

buffer - this is the buffer of bytes to write to the client

off - this is the offset within the buffer to write from

len - this is the number of bytes that are to be sent

Throws:

IOException

flush

public void flush()
           throws IOException

This method is used to flush the contents of the buffer to the client. This method will block until such time as all of the data has been sent to the client. If at any point there is an error writing the content an exception is thrown.

Specified by:

flush in interface ByteWriter

Throws:

IOException

close

public void close()
           throws IOException

This is used to close the writer and the underlying transport. If a close is performed on the writer then no more bytes can be read from or written to the transport and the client will received a connection close on their side.

Specified by:

close in interface ByteWriter

Throws:

IOException
