Methods Summary
public org.apache.http.HeaderElement[]	parseElements(org.apache.http.util.CharArrayBuffer buffer, org.apache.http.message.ParserCursor cursor) Parses a header value into elements. Parse errors are indicated as RuntimeException. Some HTTP headers (such as the set-cookie header) have values that can be decomposed into multiple elements. In order to be processed by this parser, such headers must be in the following form: header = [ element ] *( "," [ element ] ) element = name [ "=" [ value ] ] *( ";" [ param ] ) param = name [ "=" [ value ] ] name = token value = ( token | quoted-string ) token = 1*<any char except "=", ",", ";", <"> and white space> quoted-string = <"> *( text | quoted-char ) <"> text = any char except <"> quoted-char = "\" char Any amount of white space is allowed between any part of the header, element or param and is ignored. A missing value in any element or param will be stored as the empty {@link String}; if the "=" is also missing null will be stored instead. param buffer buffer holding the header value to parse param cursor the parser cursor containing the current position and the bounds within the buffer for the parsing operation return an array holding all elements of the header value throws ParseException in case of a parse error
public org.apache.http.HeaderElement	parseHeaderElement(org.apache.http.util.CharArrayBuffer buffer, org.apache.http.message.ParserCursor cursor) Parses a single header element. A header element consist of a semicolon-separate list of name=value definitions. param buffer buffer holding the element to parse param cursor the parser cursor containing the current position and the bounds within the buffer for the parsing operation return the parsed element throws ParseException in case of a parse error
public org.apache.http.NameValuePair	parseNameValuePair(org.apache.http.util.CharArrayBuffer buffer, org.apache.http.message.ParserCursor cursor) Parses a name=value specification, where the = and value are optional. param buffer the buffer holding the name-value pair to parse param cursor the parser cursor containing the current position and the bounds within the buffer for the parsing operation return the name-value pair, where the value is null if no value is specified
public org.apache.http.NameValuePair[]	parseParameters(org.apache.http.util.CharArrayBuffer buffer, org.apache.http.message.ParserCursor cursor) Parses a list of name-value pairs. These lists are used to specify parameters to a header element. Parse errors are indicated as RuntimeException. This method comforms to the generic grammar and formatting rules outlined in the Section 2.2 and Section 3.6 of RFC 2616. 2.2 Basic Rules The following rules are used throughout this specification to describe basic parsing constructs. The US-ASCII coded character set is defined by ANSI X3.4-1986. OCTET = CHAR = UPALPHA = LOALPHA = ALPHA = UPALPHA | LOALPHA DIGIT = CTL = CR = LF = SP = HT = <"> = Many HTTP/1.1 header field values consist of words separated by LWS or special characters. These special characters MUST be in a quoted string to be used within a parameter value (as defined in section 3.6). token = 1* separators = "(" | ")" | "<" | ">" | "@" | "," | ";" | ":" | "\" | <"> | "/" | "[" | "]" | "?" | "=" | "{" | "}" | SP | HT A string of text is parsed as a single word if it is quoted using double-quote marks. quoted-string = ( <"> *(qdtext | quoted-pair ) <"> ) qdtext = > The backslash character ("\") MAY be used as a single-character quoting mechanism only within quoted-string and comment constructs. quoted-pair = "\" CHAR 3.6 Transfer Codings Parameters are in the form of attribute/value pairs. parameter = attribute "=" value attribute = token value = token | quoted-string param buffer buffer holding the name-value list to parse param cursor the parser cursor containing the current position and the bounds within the buffer for the parsing operation return an array holding all items of the name-value list throws ParseException in case of a parse error
