In Xojo EndOfLine is two things
One is a global method and the other a Class.<\/p>\n\n\n\n
Because of how the compiler works it realizes when you mean each one.<\/p>\n\n\n\n
In a line of code like<\/p>\n\n\n\n
var eol as EndOfLine<\/code><\/pre>\n\n\n\nEndOfLine can, in that context, ONLY be a TYPE name. So the compiler knows you mean the EndOfLine class.<\/p>\n\n\n\n
But when you do<\/p>\n\n\n\n
dim eol as EndOfLine = EndOfLine<\/code><\/pre>\n\n\n\nit knows the FIRST one is the TYPE, the class, and the second HAS to be something that returns a value – in this case the method named EndOfLine. (And this design is something you can also use in your own code)<\/p>\n\n\n\n
What this means is that since EndOfLine is also a CLASS it can be extended. And that makes it possible to add things like a Length function.<\/p>\n\n\n\n
Public Function Length(extends e as EndOfLine) as integer\n \n Dim s As String = e\n \n Return s.length\n \nEnd Function\n<\/code><\/pre>\n\n\n\nAnd there you go. Now you can write code like<\/p>\n\n\n\n
var position as integer = otherString.IndexOf(EndOfLine)\nvar leftChars as string = otherString.left(position)\nvar eol as EndOfLine = EndOfLine\nvar rest as string = otherString.Middle(position + eol.length)<\/code><\/pre>\n\n\n\nAnd NOT have to convert the EndOfLine into a string to get the length<\/p>\n\n\n\n
