<hr><a name="_details"></a><h2>Detailed Description</h2>
Keydata objects are used to load and hold "configuration" data for a given application. load text configuration files into keyword pairs.
<p>
This class is used to load and then hold "<code>keyword = value</code>" pairs parsed from a text based "config" file that has been divided into "<code>[sections]</code>". The syntax is:
<p>
<code><pre>
[section_name]
key1=value1
key2=value2</pre></code>
<p>
Essentially, the "path" is a "keypath" into a theoretical namespace of key pairs, hence one does not use "real" filepaths that may be OS dependent. The "<code>/</code>" path refers to "<code>/etc</code>" prefixed (on UNIX) directories and this is processed within the constructor. It could refer to the <code>/config</code> prefix on QNX, or even, gasp, a "<code>C:\WINDOWS</code>". Hence, a keypath of "<code>/bayonne.d/vmhost/smtp</code>" actually resolves to a "<code>/etc/bayonne.d/vmhost.conf</code>" and loads key value pairs from the <code>[smtp]</code> section of that <code>.conf</code> file.
<p>
Similarly, something like "<code>~bayonne/smtp</code>" path refers to a "<code>~/.bayonnerc</code>" and loads key pairs from the <code>[smtp]</code> section. This coercion occurs before the name is passed to the open call.
<p>
I actually use derived keydata based classes as global initialized objects, and they hence automatically load and parse config file entries even before "main" has started.
<p>
Keydata can hold multiple values for the same key pair. This can occur either from storing a "list" of data items in a config file, or when overlaying multiple config sources (such as <code>/etc/....conf</code> and <code>~/.confrc</code> segments) into a single object. The keys are stored as cumulative (read-only/replacable) config values under a hash index system for quick retrieval.
<p>
Keydata can also load a table of "initialization" values for keyword pairs that were not found in the external file.
<p>
One typically derives an application specific keydata class to load a specific portion of a known config file and initialize it's values. One can then declare a global instance of these objects and have configuration data initialized automatically as the executable is loaded.
<p>
Hence, if I have a "[paths]" section in a "<code>/etc/server.conf?</code>" file, I might define something like:
<p>
<code><pre>
class KeyPaths : public Keydata
{
public:
KeyPaths() : Keydata("/server/paths")
{
static <a class="el" href="struct_k_e_y_d_e_f.html">KEYDEF</a> *defvalues = {
{"datafiles", "/var/server"},
{NULL, NULL}};
// override with [paths] from "~/.serverrc" if avail.
Load("~server/paths");
Load(defvalues);
}
};
KeyPaths keypaths;
</pre></code>
