TOKEN_HASH Source code

URL delimiter

TOKEN_PATH Source code

URL delimiter

TOKEN_PORT Source code

URL delimiter

TOKEN_PROTOCOL Source code

URL delimiter; to seperate protocol from the rest

TOKEN_QUERY Source code

URL delimiter

TOKEN_USER Source code

URL delimiter

TOKEN_USERPASS Source code

URL delimiter; to seperate the user and pass from the url

URL_ESCAPE Source code

URL escape token

DayNamesLong[7] Source code

names of the days, 0 = sunday

DayNamesShort[7] Source code

names of the days, 0 = sunday

LOGDATA Source code

LOGERR Source code

LOGINFO Source code

LOGWARN Source code

MonthNames[13] Source code

month names to use for date string generation

MonthOffsetLeap[13] Source code

days offsets for each month

MonthOffset[13] Source code

days offsets for each month

DateTime Source code

MD5_CTX Source code

MD5 context
buffer:

input buffer

count:

number of bits, modulo 2^64 (lsb first)

state:

state (ABCD)

xURL Source code

a better URL structure that contains all elements
hash:

the part after the #, without the leading #

hostname:

the hostname

location:

the location field, all from the hostname up to the query or hash string, includes leading /

password:

possible password that was in the url

port:

the port number specified in the URL

protocol:

protocol used, like http:/ /, https:/ /, ftp:/ /. But without the ':/ /' part. (ignore the space between the two slashes, it's required because of a bug in UE2)

query:

the part after the ?, without the leading ?

username:

username that was provided in the URL

% Source code

the float % operator is broken for our needs (numbers >2^24)

AdvSplit Source code

Split a string with quotes, quotes may appear anywhere in the string, escape the quote char with a \ to use a literal.
Qoutes are removed from the result, and escaped quotes are used as normal quotes.

Base64Decode Source code

Decode a base64 encoded string

Base64Encode Source code

base64 encode an input array

Base64EncodeLookupTable Source code

Generate the base 64 encode lookup table

basename Source code

get the base filename

daysInYear Source code

returns the number of days in a year

DecToHex Source code

convert a decimal to hexadecimal notation

dirname Source code

get the dirname of a filename, with traling slash

F Source code

FF Source code

G Source code

getPortByProtocol Source code

return the default port based on the protocol

GG Source code

H Source code

HexToDec Source code

convert a hexadecimal number to the integer counterpart

HH Source code

HTTPResponseCode Source code

return the description of a HTTP response code

I Source code

II Source code

isLeapYear Source code

returns if year is a leap year

leapsThruEndOf Source code

Logf Source code

Write a log entry

MD5Decode Source code

MD5Encode Source code

MD5Final Source code

finalize the MD5 context

MD5Init Source code

initialize the MD5 context

MD5Move Source code

MD5String Source code

return the MD5 of the input string

MD5StringArray Source code

Return the MD5 of the input string array. Concat is added after each line.

MD5Transform Source code

MD5Update Source code

update MD5 context

parseUrl Source code

parses the inURL to an xURL structure, return true when succesful

RawUrlDecode Source code

This will decode URL encoded elements. If bIgnorePlus is set to true '+' will not be changed to a space

RawUrlEncode Source code

Encode special characters, you should not use this function, it's slow and not secure, so try to avoid it. ";", "/", "?", ":", "@", "&", "=", "+", ",", "$" and " "

ReplaceChar Source code

replace part of a string

ROTATE_LEFT Source code

stringToTimestamp Source code

Parse a string to a timestamp The date string is formatted as: Wdy, DD-Mon-YYYY HH:MM:SS GMT TZoffset is the local offset to GMT

timestamp Source code

Create a UNIX timestamp.
Warning: Assumes info is passed in GMT. So make sure you correct the timezone if you are going to send a timestamp generated with this function to an other server.

timestampToDatetime Source code

converts a timestamp to a DateTime record

timestampToString Source code

convert a timestamp into a string.
Format can be one of the following strings:
"822", "1123" : RFC 822, updated by RFC 1123 (default), timezone is the TZ CODE
"850", "1036" : RFC 850, obsoleted by RFC 1036, timezone is the TZ CODE
"2822" : RFC 2822, timezone is a +0000 like string
"asctime": ANSI C's asctime() format, timezone is an integer that will increment the hour

Trim Source code

Trim leading and trailing spaces

TZtoOffset Source code

Converts a timezone code to an offset.

xURLtoLocation Source code

convert a xURL to a location string, just the location+query+hash

xURLtoString Source code

converts a xURL to a string. bIncludePassword defaults to false
