-
- All Implemented Interfaces:
BodyEncoder
class CloseEncoder extends java.lang.Object implements BodyEncoder
TheCloseEncoder
is used to close a connection once all of the content has been produced. This is typically used if the connected client supports the HTTP/1.0 protocol and there is no Connection header with the keep-alive token. For reasons of performance this should not be used for HTTP/1.1 clients.

CloseEncoder
public CloseEncoder(BodyObserver observer, ByteWriter writer)
Constructor for theCloseEncoder
object. This is used to create a producer that will close the underlying socket as a means to signal that the response is fully sent. This is typically used with HTTP/1.0 connections.- Parameters:
writer
- this is used to send to the underlying transportobserver
- this is used to deliver signals to the kernel

Method Detail

encode
public void encode(byte[] array) throws java.io.IOException
This method is used to encode the provided array of bytes in a HTTP/1.1 complaint format and sent it to the client. Once the data has been encoded it is handed to the transport layer within the server, which may choose to buffer the data if the content is too small to send efficiently or if the socket is not write ready.- Specified by:
encode
in interfaceBodyEncoder
- Parameters:
array
- this is the array of bytes to send to the client- Throws:
java.io.IOException
-
encode
public void encode(byte[] array, int off, int len) throws java.io.IOException
This method is used to encode the provided array of bytes in a HTTP/1.1 complaint format and sent it to the client. Once the data has been encoded it is handed to the transport layer within the server, which may choose to buffer the data if the content is too small to send efficiently or if the socket is not write ready.- Specified by:
encode
in interfaceBodyEncoder
- Parameters:
array
- this is the array of bytes to send to the clientoff
- this is the offset within the array to send fromlen
- this is the number of bytes that are to be sent- Throws:
java.io.IOException
-
encode
public void encode(java.nio.ByteBuffer buffer) throws java.io.IOException
This method is used to encode the provided buffer of bytes in a HTTP/1.1 compliant format and sent it to the client. Once the data has been encoded it is handed to the transport layer within the server, which may choose to buffer the data if the content is too small to send efficiently or if the socket is not write ready.- Specified by:

in interfaceBodyEncoder
- Parameters:
buffer
- this is the buffer of bytes to send to the client- Throws:
java.io.IOException
-
encode
public void encode(java.nio.ByteBuffer buffer, int off, int len) throws java.io.IOException
This method is used to encode the provided buffer of bytes in a HTTP/1.1 compliant format and sent it to the client. Once the data has been encoded it is handed to the transport layer within the server, which may choose to buffer the data if the content is too small to send efficiently or if the socket is not write ready.- Specified by:
encode
in interfaceBodyEncoder
- Parameters:
buffer
- this is the buffer of bytes to send to the clientoff
- this is the offset within the buffer to send fromlen
- this is the number of bytes that are to be sent- Throws:
java.io.IOException
-
flush
public void flush() throws java.io.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 sending the content an exception is thrown.- Specified by:
flush
in interfaceBodyEncoder
- Throws:
java.io.IOException
-
close
public void close() throws java.io.IOException
This is used to signal to the producer that all content has been written and the user no longer needs to write. This will close the underlying transport which tells the client that all of the content has been sent over the connection.- Specified by:
close
in interfaceBodyEncoder
- Throws:
java.io.IOException
