=head1 DESCRIPTION
|
||
|
|
|
||
|
|
B<THIS MODULE HAS BEEN DEPRECATED>. Please use a subclass of
|
||
|
|
esmith::DB::db instead, such as esmith::AccountsDB or esmith::ConfigDB.
|
||
|
|
|
||
|
|
I<Do not try to change this module>. Much code depends on subtle
|
||
|
|
nuances and bugs and you will break things if you try to fix it.
|
||
|
|
Instead, move any existing code away from esmith::db and towards
|
||
|
|
esmith::DB::db.
|
||
|
|
|
||
|
|
|
||
|
|
This module provides utility routines for manipulating e-smith
|
||
|
|
configuration data. OO and non-OO versions of the routines are provided.
|
||
|
|
For example, db_set() is the non-OO while set() can be called with an
|
||
|
|
object reference.
|
||
|
|
|
||
|
|
E-Smith DB entries have three parts. A key, a type and a hash of
|
||
|
|
properties.
|
||
|
|
|
||
|
|
key squid
|
||
|
|
type cephalopod
|
||
|
|
properties arms => 10
|
||
|
|
species => Loligo

|
Enters a new $key into the %config or replaces an existing $key. It
|
||
|
|
sets the $type and optionally %properties.
|
||
|
|
|
||
|
|
As a "bug which has become a feature" you can feed db_set() the
|
||
|
|
$raw_value for a $key (ie. 'type|prop1|val1|prop2|val2') and it will
|
||
|
|
setup the types and properties properly. I<Do not depend on this> but
|
||
|
|
don't change it either. There's code that depends on this behavior.
|
||
|
|
|
||
|
|
It returns true on success, false on failure.
|
||
|
|
|
||
|
|
If the $key contains a newline it will fail.

Reads the $type and %properties for the given $key in %config.

In scalar context it returns the raw value of $config{$key} B<NOT> the

type! But it unescapes newlines. I<Use db_get_type() instead>.
