This class provides advanced methods on Strings. It is ideally used with
using StringTools and then acts as an extension
to the String class.
If the first argument to any of the methods is null, the result is unspecified.
Static methods
statichtmlEscape(s:String, ?quotes:Bool):String
Escapes HTML special characters of the string s.
The following replacements are made:
&becomes&<becomes<>becomes>
If quotes is true, the following characters are also replaced:
"becomes"'becomes'
staticstartsWith(s:String, start:String):Bool
Tells if the string s starts with the string start.
If start is null, the result is unspecified.
If start is the empty String "", the result is true.
staticendsWith(s:String, end:String):Bool
Tells if the string s ends with the string end.
If end is null, the result is unspecified.
If end is the empty String "", the result is true.
staticisSpace(s:String, pos:Int):Bool
Available on clay
Tells if the character in the string s at position pos is a space.
A character is considered to be a space character if its character code is 9,10,11,12,13 or 32.
If s is the empty String "", or if pos is not a valid position within
s, the result is false.
staticltrim(s:String):String
Removes leading space characters of s.
This function internally calls isSpace() to decide which characters to
remove.
If s is the empty String "" or consists only of space characters, the
result is the empty String "".
staticrtrim(s:String):String
Available on clay
Removes trailing space characters of s.
This function internally calls isSpace() to decide which characters to
remove.
If s is the empty String "" or consists only of space characters, the
result is the empty String "".
statictrim(s:String):String
Removes leading and trailing space characters of s.
This is a convenience function for ltrim(rtrim(s)).
staticreplace(s:String, sub:String, by:String):String
Replace all occurrences of the String sub in the String s by the
String by.
If sub is the empty String "", by is inserted after each character
of s except the last one. If by is also the empty String "", s
remains unchanged.
If sub or by are null, the result is unspecified.
statichex(n:Int, ?digits:Int):String
Encodes n into a hexadecimal representation.
If digits is specified, the resulting String is padded with "0" until
its length equals digits.
staticinlinefastCodeAt(s:String, index:Int):Int
Returns the character code at position index of String s, or an
end-of-file indicator at if position equals s.length.
This method is faster than String.charCodeAt() on some platforms, but
the result is unspecified if index is negative or greater than
s.length.
End of file status can be checked by calling StringTools.isEof() with
the returned value as argument.
This operation is not guaranteed to work if s contains the \0
character.
staticinlineunsafeCodeAt(s:String, index:Int):Int
Returns the character code at position index of String s, or an
end-of-file indicator at if position equals s.length.
This method is faster than String.charCodeAt() on some platforms, but
the result is unspecified if index is negative or greater than
s.length.
This operation is not guaranteed to work if s contains the \0
character.
staticlpad(s:String, c:String, l:Int):String
Available on clay native, unity
Concatenates c to s until s.length is at least l.
If c is the empty String "" or if l does not exceed s.length,
s is returned unchanged.
If c.length is 1, the resulting String length is exactly l.
Otherwise the length may exceed l.
If c is null, the result is unspecified.
