Inheritance graph

Description

This class implements the interface to a simple regexp engine with the following capabilities:

.	Matches any character.
[abc]	Matches a, b or c.
[a-z]	Matches any character a to z inclusive.
[^ac]	Matches any character except a and c.
(x)	Matches x (x might be any regexp) If used with split, this also puts the string matching x into the result array.
x*	Matches zero or more occurances of 'x' (x may be any regexp).
x+	Matches one or more occurances of 'x' (x may be any regexp).
x\|y	Matches x or y. (x or y may be any regexp).
xy	Matches xy (x and y may be any regexp).
^	Matches beginning of string (but no characters).
$	Matches end of string (but no characters).
\<	Matches the beginning of a word (but no characters).
\>	Matches the end of a word (but no characters).

Note that \ can be used to quote these characters in which case they match themselves, nothing else. Also note that when quoting these something in Pike you need two \ because Pike also uses this character for quoting.

Method create: Regexp.SimpleRegexp Regexp.SimpleRegexp(string re)
Description: When create is called, the current regexp bound to this object is cleared. If a string is sent to create(), this string will be compiled to an internal representation of the regexp and bound to this object for laters calls to e.g. match or split. Calling create() without an argument can be used to free up a little memory after the regexp has been used.
