Method Detail

getNewInstance

public Handler getNewInstance(Connection con,
                              TrafficLoggerHandler tlh,
                              HttpHeader header,

                              long size)

Description copied from interface: HandlerFactory

Get a new Handler for the given request made.

Specified by:

getNewInstance in interface HandlerFactory

Overrides:

getNewInstance in class BaseHandler

Parameters:

con - the Connection handling the request.

tlh - the Traffic logger handler.

header - the request.

bufHandle - the client side buffer handle (may contain the next request).

webHeader - the response.

content - the resource.

mayCache - if the handler may cache the response.

mayFilter - if the handler may filter the response.

size - the Size of the data beeing handled (-1 = unknown length).

changesContentSize

public boolean changesContentSize()

We may remove trailers, so we may modify the content. ®return true this handler modifies the content.

Specified by:

changesContentSize in interface Handler

Overrides:

changesContentSize in class BaseHandler

Returns:

true if Content-Lenght may be changed by this handler typically used for handlers that may modify the content. Return false if this handler will not change the size.

send

protected void send()

Overrides:

send in class BaseHandler

bufferRead

public void bufferRead(BufferHandle bufHandle)

Description copied from interface: BlockListener

A buffer has been read, the buffer has been flip:ed before this call is made so position and remaining are valid.

Specified by:

bufferRead in interface BlockListener

Overrides:

bufferRead in class BaseHandler
