ABSTRACT

Config::Backend::String is a backend module for Config::Frontend.

Description

`new(\$strref) --> Config::Backend::String`

If called with a reference to a string, will instantiate a Config::Backend::String object. Otherwise will attempt to die.

`set(var,val) --> void`

This method will set variable var to value <val>. All set methods will immediately reset the value of the string that the object references to. So, all changes through 'set' will be visibile imediately to the program environment.

`get(var) --> string`

Returns undef, if var does not exist. Returns the value of var (string), otherwise.

`del(var) --> void`

Delets var from the string.

`variables() --> list`

Will return a list of all variables in Conf::String.
