◆ getPattern()

ilAssLacExpressionManufacturer::getPattern ( )

This function create a regular expression to match all expression in a condition.


The following string is created by this function '/%[0-9]+%|#[0-9]+#|+[0-9]++|Q[0-9]+([^[|0-9]|$)|Q[0-9]+[[0-9]+]|~.*?~'
It matches all expression in a condition and is divided into the following parts:

Qn        /Q[0-9]+(?!\[)/
Qn[m]     /Q[0-9]+\[[0-9]+\]/
n%       /%[0-9]+%/
+n+       /\+[0-9]+\+/
n#       /#[0-9]+#/
~TEXT~    /~.*?~/                               Hier gibt es noch Probleme, wenn im Text ein ~ enthalten ist
Returns
string
