java.lang.Object

org.apache.olingo.server.core.prefer.PreferParser

public class PreferParser
extends Object

Parses the values of Prefer HTTP header fields.

See RFC 7240 for details; there the following grammar is defined:

 Prefer = "Prefer" ":" 1#preference
 preference = token [ BWS "=" BWS word ] *( OWS ";" [ OWS parameter ] )
 parameter = token [ BWS "=" BWS word ]
 token = 1*tchar
 tchar = "!" / "#" / "$" / "%" / "&" / "'" / "*"
 / "+" / "-" / "." / "^" / "_" / "`" / "|" / "~" / DIGIT / ALPHA
 word = token / quoted-string
 quoted-string = DQUOTE *( qdtext / quoted-pair ) DQUOTE
 qdtext = HTAB / SP / %x21 / %x23-5B / %x5D-7E / %x80-FF
 quoted-pair = "\" ( HTAB / SP / %x21-7E / %x80-FF )
 OWS = *( SP / HTAB ) ; optional whitespace
 BWS = OWS ; "bad" whitespace
 

Values with illegal syntax do not contribute to the result but no exception is thrown.
