public class WOSMILDocument

extends WOSMILElement

WOSMILDocument creates content for a SMIL "smil" element. This is the root element of a SMIL document. A smil document contains one "head" element and one "body" element.

The WOSMIL framework is designed to let WebObjects developers develop applications that produce SMIL content for SMIL 1.0 compliant players while taking advantage of WebObject's dynamic elements and template engine. This way, a WOComponent can contain standard SMIL elements whose attributes can be generated dynamically, in much the same way as WebObjects is used for HTML applications.

It is expected that developers have some understanding of SMIL. The SMIL recommendation is available here. Each WOSMIL component closely mirrors the elements of the SMIL specifcation. So, for instance, a typical SMIL WOComponent would contain a WOSMILDocument component, within which would be a WOSMILHead and WOSMILBody component. Within the document's WOSMILHead component, there would be a WOSMILHeadLayout and multiple WOSMILHeadMeta component.

The bindings of each WOSMIL component also closely follow the attributes of their SMIL element counterpart. See the documentation about a specific class to see what bindings are available and how they relate to that class's SMIL element attributes.

Binding	SMIL attribute
elementID	id
otherTagString	use this binding to add custom attributes

Constructor Detail

WOSMILDocument

public WOSMILDocument(WOContext context)

Creates a WOSMILDocument.

Parameters:

context - the context this component is created with

Method Detail

appendToResponse

public void appendToResponse(WOResponse resp,
                             WOContext cont)

Sets the response header "content-type" to "application/smil".

Overrides:

appendToResponse in class WOComponent

Parameters:

resp - WOResponse to add content to

cont - WOContext of the request/response loop

WOElement.appendToResponse(com.webobjects.appserver.WOResponse, com.webobjects.appserver.WOContext)

otherTagString

public String otherTagString()

Description copied from class: WOSMILElement

Returns the value of the otherTagString property.

Overrides:

otherTagString in class WOSMILElement

Following copied from class: com.webobjects.smil.WOSMILElement

Returns:

value of the otherTagString property

synchronizesVariablesWithBindings

public boolean synchronizesVariablesWithBindings()

Description copied from class: WOComponent

Indicates if the push-pull of values in the parent component is enabled. Returns whether a nested component pulls all values down from its parent and pushes all values to its parent before and after each phase of the request-response loop. This method returns false for stateless components (unless you override isStateless and return true), and true otherwise. Override this method to create a non-synchronizing component.

Overrides:

synchronizesVariablesWithBindings in class WOSMILElement

Returns:

false
