<p>Ace::Model - Get information about AceDB models</p>

<h1><a name="synopsis">SYNOPSIS</a></h1>
<pre>
use Ace;
my $db = Ace->connect(-path=>'/usr/local/acedb/elegans');
my $model = $db->model('Author');
print $model;

<h1><a name="description">DESCRIPTION</a></h1>
<p>This class is provided for access to AceDB class models. It provides
the model in human-readable form, and does some limited but useful
parsing on your behalf.</p>
<p>Ace::Model objects are obtained either by calling an Ace database
handle's <code>model()</code> method to retrieve the model of a named class, or by
calling an Ace::Object's <code>model()</code> method to retrieve the object's
particular model.</p>
<p>
</p>

<h1><a name="methods">METHODS</a></h1>
<p>
</p>
<h2><a name="new__"><code>new()</code></a></h2>
<pre>
$model = Ace::Model->new($model_data);</pre>
<p>This is a constructor intended only for use by Ace and Ace::Object
classes. It constructs a new Ace::Model object from the raw string
data in models.wrm.</p>
<p>
</p>
<h2><a name="name__"><code>name()</code></a></h2>
<pre>
$name = $model->name;</pre>
<p>This returns the class name for the model.</p>
<p>
</p>
<h2><a name="tags__"><code>tags()</code></a></h2>
<pre>
@tags = $model->tags;</pre>
<p>This returns a list of all the valid tags in the model.</p>
<p>
</p>
<h2><a name="valid_tag__"><code>valid_tag()</code></a></h2>
<pre>
$boolean = $model->valid_tag($tag);</pre>
<p>This returns true if the given tag is part of the model.</p>
<p>
</p>
<h2><a name="path__"><code>path()</code></a></h2>
<pre>
@path = $model->path($tag)</pre>
<p>Returns the path to the indicated tag, returning a list of intermediate tags.
For example, in the C elegans ?Locus model, the path for 'Compelementation_data"
will return the list ('Type','Gene').</p>
<p>
</p>
<h2><a name="asstring__"><code>asString()</code></a></h2>
<pre>
print $model->asString;</pre>
<p><code>asString()</code> returns the human-readable representation of the model with
comments stripped out. Internally this method is called to
automatically convert the model into a string when appropriate. You
need only to start performing string operations on the model object in
order to convert it into a string automatically:</p>
<pre>
print "Paper is unique" if $model=~/Paper ?Paper UNIQUE/;</pre>
