Ace::Model(3)	      User Contributed Perl Documentation	 Ace::Model(3)

NAME
       Ace::Model - Get	information about AceDB	models

SYNOPSIS
	 use Ace;
	 my $db	= Ace->connect(-path=>'/usr/local/acedb/elegans');
	 my $model = $db->model('Author');
	 print $model;
	 $name = $model->name;
	 @tags = $model->tags;
	 print "Paper is a valid tag" if $model->valid_tag('Paper');

DESCRIPTION
       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.

       Ace::Model objects are obtained either by calling an Ace	database
       handle's	model()	method to retrieve the model of	a named	class, or by
       calling an Ace::Object's	model()	method to retrieve the object's
       particular model.

METHODS
   new()
	 $model	= Ace::Model->new($model_data);

       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.

   name()
	 $name = $model->name;

       This returns the	class name for the model.

   tags()
	  @tags	= $model->tags;

       This returns a list of all the valid tags in the	model.

   valid_tag()
	  $boolean  = $model->valid_tag($tag);

       This returns true if the	given tag is part of the model.

   path()
	  @path	= $model->path($tag)

       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').

   asString()
	  print	$model->asString;

       asString() 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:

	  print	"Paper is unique" if $model=~/Paper ?Paper UNIQUE/;
