NAME

Ace::Model - Get information about AceDB models

CONTENTS

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/;
