| Overview |  |
| is_IPv4address/1 | parse host string, throw an exception if it doesn't conform to the format specified in RFC3261 chapter 25.1 page 218. |
| is_IPv6reference/1 | parse host string, throw an exception if it doesn't conform to the format specified in RFC3261 chapter 25.1 page 218. |
| is_alpha/1 | Check if Char is alphanumeric. |
| is_alphanum/1 | Check if Char is alphanumeric or a digit. |
| is_digit/1 | Check if Char is a digit. |
| is_hostname/1 | parse host string, throw an exception if it doesn't conform to the format specified in RFC3261 chapter 25.1 p218. |
| is_qval/1 | parse a qvalue string qvalue = ( "0" [ "." 0*3DIGIT ] ) / ( "1" [ "." 0*3("0") ] ) - RFC 3261. |
| is_token/1 | Check if Str is a 'token'. |
| parse_host/1 | return Host if it is wellformed, a exception is thrown if the Host is malformed the host rule alows for a varity of formats: hostname ipv4address ipv6reference. |
| parse_hostport/1 | splits the string into it's two parts, a exception is thrown if the Host or Port is malformed the host:port section of the sip url can be formated in a varity of ways: hostname:port hostname ipv4address:port ipv4address [ipv6reference]:port ipv6reference. |
| split_fields/2 | split FieldStr into two parts where Sep is encountered
Example, if Sep = @ then: "foo@bar" = {"foo", "bar"}
"foo" = {"foo"} "foo@" = throw() "@bar" = throw()
"foo@bar" = throw() "@" = throw() "" = {""} XXX is this
ok ? nothing currently depends on this behaviour.. |
| split_non_quoted/2 | Split In using Delim as delimeter, but don't split on delimeters inside quotes. |
| split_quoted_string/1 | Parse out a quoted string from In and return the quoted part as First and the rest as Second. |
| str_to_float/1 | convert Str containing float() or integer() value, to a float(). |
| str_to_qval/1 | parse a qvalue string qvalue = ( "0" [ "." 0*3DIGIT ] ) / ( "1" [ "." 0*3("0") ] ) - RFC 3261. |
| strip/3 | works like string:strip/3 but can strip several types of char() at once. |
is_IPv4address(Host::Str) -> Str
parse host string, throw an exception if it doesn't conform to the format specified in RFC3261 chapter 25.1 page 218. Note : this function only matches IPv4 hostnames
is_IPv6reference(IPv6Str) -> true | false
parse host string, throw an exception if it doesn't conform to the format specified in RFC3261 chapter 25.1 page 218. Note : this function only matches IPv6 hostnames
is_alpha(Char) -> true | false
Check if Char is alphanumeric. Based on RFC3261 BNF, chapter 25.
is_alphanum(Char) -> true | false
Check if Char is alphanumeric or a digit. Based on RFC3261 BNF, chapter 25.
is_digit(Char) -> true | false
Check if Char is a digit. Based on RFC3261 BNF, chapter 25.
is_hostname(Host::Str) -> true
parse host string, throw an exception if it doesn't conform to the format specified in RFC3261 chapter 25.1 p218. Fails hard (with a badmatch or error 'invalid_hostname' on errors). Note : this function only matches symbolic hostnames These rules are the same: is_digit = [0-9] is_alpha = [A-Za-z] is_alphanum = [A-Za-z0-9]
is_qval(Str) -> true | false
parse a qvalue string qvalue = ( "0" [ "." 0*3DIGIT ] ) / ( "1" [ "." 0*3("0") ] ) - RFC 3261
is_token(Str) -> true | false
Check if Str is a 'token'. Based on RFC3261 BNF, chapter 25.
parse_host(Host) -> Host
throws {error, Reason} | {'EXIT', Reason}
return Host if it is wellformed, a exception is thrown if the Host is malformed the host rule alows for a varity of formats: hostname ipv4address ipv6reference
parse_hostport(HostPort) -> {Host, Port}
throws {error, Reason} | {'EXIT', Reason}
splits the string into it's two parts, a exception is thrown if the Host or Port is malformed the host:port section of the sip url can be formated in a varity of ways: hostname:port hostname ipv4address:port ipv4address [ipv6reference]:port ipv6reference
split_fields(FieldStr, Sep) -> {First, Second} | {First}
throws {error, Reason}
split FieldStr into two parts where Sep is encountered
Example, if Sep = @ then: "foo@bar" = {"foo", "bar"}
"foo" = {"foo"} "foo@" = throw() "@bar" = throw()
"foo@bar" = throw() "@" = throw() "" = {""} XXX is this
ok ? nothing currently depends on this behaviour.
split_non_quoted(Delim, In) -> {ok, Result} | {error, Reason}
Split In using Delim as delimeter, but don't split on delimeters inside quotes.
split_quoted_string(Rest::In) -> {ok, First, Second}
Parse out a quoted string from In and return the quoted part as First and the rest as Second.
str_to_float(Str) -> float()
throws {error, string_not_float_or_integer}
convert Str containing float() or integer() value, to a float(). Note : user need to strip any preceding or trailing spaces (or other chars themselves) XXX q_value(...) in contact.erl uses similar code XXX this should be in a utility module
str_to_qval(R::Str) -> float()
throws {error, malformed_beging_of_qvalue} | {error, wrong_number_of_chars_in_q_value} | {error, q_value_out_of_range}
parse a qvalue string qvalue = ( "0" [ "." 0*3DIGIT ] ) / ( "1" [ "." 0*3("0") ] ) - RFC 3261
strip(Str, X2::Direction, StripChars) -> NewString
works like string:strip/3 but can strip several types of char() at once
