class StringTools

no package

@:keep@:directlyUsed

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

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.

statichtmlEscape(s:String, ?quotes:Bool):String

Escapes HTML special characters of the string s.

The following replacements are made:

  • & becomes &
  • < becomes &lt;
  • > becomes &gt;

If quotes is true, the following characters are also replaced:

  • " becomes &quot;
  • ' becomes &#039;

staticisSpace(s:String, pos:Int):Bool

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.

staticlpad(s:String, c:String, l:Int):String

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.

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 "".

staticrpad(s:String, c:String, l:Int):String

Appends 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.

staticrtrim(s:String):String

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 "".

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.

statictrim(s:String):String

Removes leading and trailing space characters of s.

This is a convenience function for ltrim(rtrim(s)).
