Class Overview

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.

Fields

public static final BasicLineFormatter DEFAULT

Added in API level 1

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.

Public Constructors

public BasicLineFormatter ()

Added in API level 1

Public Methods

public CharArrayBuffer appendProtocolVersion (CharArrayBuffer buffer, ProtocolVersion version)

Added in API level 1

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.

Parameters
buffer a buffer to which to append, or null
version the protocol version to format
Returns
  • a buffer with the formatted protocol version appended. The caller is allowed to modify the result buffer. If the buffer argument is not null, the returned buffer is the argument buffer.

public static final String formatHeader (Header header, LineFormatter formatter)

Added in API level 1

Formats a header.

Parameters
header the header to format
formatter the formatter to use, or null for the default
Returns
  • the formatted header

public CharArrayBuffer formatHeader (CharArrayBuffer buffer, Header header)

Added in API level 1

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.

Parameters
buffer a buffer available for formatting, or null. The buffer will be cleared before use.
header the header to format
Returns
  • a buffer holding the formatted header, never null. The returned buffer may be different from the argument buffer.

public static final String formatProtocolVersion (ProtocolVersion version, LineFormatter formatter)

Added in API level 1

Formats a protocol version.

Parameters
version the protocol version to format
formatter the formatter to use, or null for the default
Returns
  • the formatted protocol version

public CharArrayBuffer formatRequestLine (CharArrayBuffer buffer, RequestLine reqline)

Added in API level 1

Formats a request line.

Parameters
buffer a buffer available for formatting, or null. The buffer will be cleared before use.
reqline the request line to format
Returns
  • the formatted request line

public static final String formatRequestLine (RequestLine reqline, LineFormatter formatter)

Added in API level 1

Formats a request line.

Parameters
reqline the request line to format
formatter the formatter to use, or null for the default
Returns
  • the formatted request line

public static final String formatStatusLine (StatusLine statline, LineFormatter formatter)

Added in API level 1

Formats a status line.

Parameters
statline the status line to format
formatter the formatter to use, or null for the default
Returns
  • the formatted status line

public CharArrayBuffer formatStatusLine (CharArrayBuffer buffer, StatusLine statline)

Added in API level 1

Formats a status line.

Parameters
buffer a buffer available for formatting, or null. The buffer will be cleared before use.
statline the status line to format
Returns
  • the formatted status line

Protected Methods

protected void doFormatHeader (CharArrayBuffer buffer, Header header)

Added in API level 1

Actually formats a header. Called from formatHeader(Header, LineFormatter).

Parameters
buffer the empty buffer into which to format, never null
header the header to format, never null

protected void doFormatRequestLine (CharArrayBuffer buffer, RequestLine reqline)

Added in API level 1

Actually formats a request line. Called from formatRequestLine(RequestLine, LineFormatter).

Parameters
buffer the empty buffer into which to format, never null
reqline the request line to format, never null

protected void doFormatStatusLine (CharArrayBuffer buffer, StatusLine statline)

Added in API level 1

Actually formats a status line. Called from formatStatusLine(StatusLine, LineFormatter).

Parameters
buffer the empty buffer into which to format, never null
statline the status line to format, never null

protected int estimateProtocolVersionLen (ProtocolVersion version)

Added in API level 1

Guesses the length of a formatted protocol version. Needed to guess the length of a formatted request or status line.

Parameters
version the protocol version to format, or null
Returns
  • the estimated length of the formatted protocol version, in characters

protected CharArrayBuffer initBuffer (CharArrayBuffer buffer)

Added in API level 1

Obtains a buffer for formatting.

Parameters
buffer a buffer already available, or null
Returns
  • the cleared argument buffer if there is one, or a new empty buffer that can be used for formatting
