↳ | org.apache.http.message.BasicLineFormatter |
Interface for formatting elements of the HEAD section of an HTTP message.
This is the complement to
LineParser
.
There are individual methods for formatting a request line, a
status line, or a header line. The formatting does
not
include the
trailing line break sequence CR-LF.
The formatted lines are returned in memory, the formatter does not depend
on any specific IO mechanism.
Instances of this interface are expected to be stateless and thread-safe.

org.apache.http.message.LineFormatter
|
A default instance of this class, for use as default or fallback.
Note that
BasicLineFormatter
is not a singleton, there can
be many instances of the class itself and of derived classes.
The instance here provides non-customized, default behavior.
Formats a protocol version.
This method does
not
follow the general contract for
buffer
arguments.
It does
not
clear the argument buffer, but appends instead.
The returned buffer can always be modified by the caller.
Because of these differing conventions, it is not named
formatProtocolVersion
.

Formats a header.
header | the header to format |

Formats a header.
Due to header continuation, the result may be multiple lines.
In order to generate well-formed HTTP, the lines in the result
must be separated by the HTTP line break sequence CR-LF.
There is
no
trailing CR-LF in the result.
See the class comment for details about the buffer argument.
