=head1 NAME
HTML::Object::DOM::Element::Object - HTML Object DOM Object Class
=head1 SYNOPSIS
use HTML::Object::DOM::Element::Object;
my $object = HTML::Object::DOM::Element::Object->new ||
die( HTML::Object::DOM::Element::Object->error, "\n" );
=head1 VERSION
v0.2.0
=head1 DESCRIPTION
This interface provides special properties and methods (beyond those on the L<HTML::Object::Element> interface it also has available to it by inheritance) for manipulating the layout and presentation of C<<object>> element, representing external resources.
It is now deprecated and similarly to L<<video>|HTML::Object::DOM::Element::Video> and L<<audio>|HTML::Object::DOM::Element::Audio> tags, HTML object tag was used to enable embedding multimedia files into the web page, such as audio, video, Flash, PDF, ActiveX, and Java Applets.
<object width="300" height="200" data="https://example.org/some/where/image.png" type="image/png">Image not found.</object>
<object data="document.pdf" width="500" height="350" type="application/pdf"></object>

=head1 PROPERTIES
Inherits properties from its parent L<HTML::Object::DOM::Element>
=head2 align
Is a string representing an enumerated property indicating alignment of the element's contents with respect to the surrounding context. The possible values are C<left>, C<right>, C<justify>, and C<center>.
=head2 archive
Is a string that reflects the archive HTML attribute, containing a list of archives for resources for this object.
=head2 border
Is a string that reflects the border HTML attribute, specifying the width of a border around the object.
=head2 code
Is a string representing the name of an applet class file, containing either the applet's subclass, or the path to get to the class, including the class file itself.
=head2 codeBase
Is a string that reflects the codebase HTML attribute, specifying the base path to use to resolve relative URIs.
=head2 codeType
Is a string that reflects the codetype HTML attribute, specifying the content type of the data.
=head2 contentDocument
Normally this is a read-only property, but under perl, you can set or get a L<HTML::Object::DOM::Document> object.
Under JavaScript, this returns a L<Document|HTML::Object::DOM::Document> representing the active document of the object element's nested browsing context, if any; otherwise C<undef>.
=head2 contentWindow
Normally this returns C<undef> under perl, but you can set it to a L<HTML::Object::DOM::WindowProxy> object.
Under JavaScript, this is a read-only property that returns a C<WindowProxy> representing the window proxy of the object element's nested browsing context, if any; otherwise C<undef>.
=head2 data
Sets or gets an L<URI> object.
This returns a string, turned into an L<URI>, that reflects the data HTML attribute, specifying the address of a resource's data.
=head2 declare
Is a boolean value that reflects the declare HTML attribute, indicating that this is a declaration, not an instantiation, of the object.
=head2 form
Read-only.
Returns a L<HTML::Object::DOM::Element::Form> representing the object element's form owner, or C<undef> if there is not one.
Example:
<form action="/some/where/script.pl" id="form1">
Email: <input type="text" name="email" /><br />
<input type="submit" value="Submit" />
</form>
<object form="form1" width="300" height="200" data="https://example.org/some/where/image.png" type="image/png">Image not found.</object>
=head2 height
Returns a string that reflects the height HTML attribute, specifying the displayed height of the resource in CSS pixels.
=head2 hspace
Is a long representing the horizontal space in pixels around the control.
=head2 name
Returns a string that reflects the name HTML attribute, specifying the name of the browsing context.
Example:
<object data="document.pdf" width="300" height="200" name="board_resolution">Alternate text.</object>
=head2 standby
Is a string that reflects the standby HTML attribute, specifying a message to display while the object loads.
=head2 type
Is a string that reflects the type HTML attribute, specifying the MIME type of the resource.
=head2 typemustmatch
C<typemustmatch> indicates that the resource should only be embedded if the value of the type attribute matches with the type of the resource provided in the data attribute.
<object data="flashFile.swf" type="image/png" width="550" height="450" typemustmatch></object>
=head2 useMap
Is a string that reflects the usemap HTML attribute, specifying a <map> element to use.
Example:
<img src="image.png" width="320" height="320" alt="Dinosaurs" usemap="#dinosaursmap" />
<map name="dinosaursmap">
<area shape="rect" coords="34,44,270,350" alt="Pterodactyl" href="https://example.org/tag/Pterodactyl" />
<area shape="rect" coords="290,172,333,250" alt="Triceratop" href="https://example.org/tag/Triceratop" />
<area shape="circle" coords="337,300,44" alt="Tyrannosaurus" href="https://example.org/tag/Tyrannosaurus" />
</map>
=head2 validationMessage
Normally this is read-only, but under perl you can set whatever string value you want.
Under JavaScript, this returns a string representing a localized message that describes the validation constraints that the control does not satisfy (if any). This is the empty string if the control is not a candidate for constraint validation (willValidate is false), or it satisfies its constraints.
Example:
my $String = HTMLObjectElement->validationMessage;
=head2 validity
Read-only.
Returns a L<HTML::Object::DOM::ValidityState> with the validity states that this element is in.
=head2 vspace
Is a long representing the horizontal space in pixels around the control.
=head2 width
Is a string that reflects the width HTML attribute, specifying the displayed width of the resource in CSS pixels.
=head2 willValidate
Normally this is read-only, but under perl you can set whatever boolean value you want.
Under JavaScript, this returns a boolean value that indicates whether the element is a candidate for constraint validation. Always false for L<HTML::Object::DOM::Element::Object> objects.
=head1 METHODS
Inherits methods from its parent L<HTML::Object::DOM::Element>
=head2 checkValidity
Normally this is read-only, but under perl you can set whatever boolean value you want.
Under JavaScript, this returns a boolean value that always is true, because object objects are never candidates for constraint validation.
=head2 setCustomValidity
Sets a custom validity message for the element. If this message is not the empty string, then the element is suffering from a custom validity error, and does not validate.
Returns a L<scalar object|Module::Generic::Scalar>
Example:
use feature 'signatures';
sub validate( $inputID )
{
my $input = $doc->getElementById( $inputID );
my $validityState = $input->validity;
if( $validityState->valueMissing )
{
$input->setCustomValidity( 'You gotta fill this out, yo!' );
}
elsif( $validityState->rangeUnderflow )
{
$input->setCustomValidity( 'We need a higher number!' );
}
elsif( $validityState->rangeOverflow )
{
$input->setCustomValidity( 'Thats too high!' );
}
else
{
$input->setCustomValidity( '' );
}
$input->reportValidity();
}
