org.apache.http.message.LineParser |
Known Indirect Subclasses |
Interface for parsing lines in the HEAD section of an HTTP message. There are individual methods for parsing a request line, a status line, or a header line. The lines to parse are passed in memory, the parser does not depend on any specific IO mechanism. Instances of this interface are expected to be stateless and thread-safe.

|
Checks whether there likely is a protocol version in a line.
This method implements a
heuristic
to check for a
likely protocol version specification. It does
not
guarantee that
parseProtocolVersion(CharArrayBuffer, ParserCursor)
would not
detect a parse error.
This can be used to detect garbage lines before a request
or status line.
buffer | a buffer holding the line to inspect |
---|---|
cursor | the cursor at which to check for a protocol version, or negative for "end of line". Whether the check tolerates whitespace before or after the protocol version is implementation dependent. |
true
if there is a protocol version at the
argument index (possibly ignoring whitespace),
false
otherwise
Creates a header from a line. The full header line is expected here. Header continuation lines must be joined by the caller before invoking this method.
buffer | a buffer holding the full header line. This buffer MUST NOT be re-used afterwards, since the returned object may reference the contents later. |

Parses the textual representation of a protocol version. This is needed for parsing request lines (last element) as well as status lines (first element).
buffer | a buffer holding the protocol version to parse |

cursor | the parser cursor containing the current position and the bounds within the buffer for the parsing operation |
