Method Detail

getResourceLoaderClass

public Class getResourceLoaderClass()

Description copied from interface: ResourceHandler

Return a Class object whose instance can decode the url generated by this class in the getResourceUri method and use that info to locate the resource data represented by this object. When a browser requests the data in the URL generated by this class and its callers, an instance of the returned class shall be created to decode the remainder of the url and serve the resource.

Specified by:

getResourceLoaderClass in interface ResourceHandler

Returns:

a class which implements org.apache.myfaces.component.html.util.ResourceLoader

ResourceHandler.getResourceLoaderClass()

getResourceUri

public String getResourceUri(javax.faces.context.FacesContext context)

Description copied from interface: ResourceHandler

Returns the uri part which is used by the resourceloader to identify the resource to load. This URI will be interpreted by an instance of the class returned by getResourceLoaderClass.

getResourceUri in interface ResourceHandler

ResourceHandler.getResourceUri(javax.faces.context.FacesContext)

equals

public boolean equals(Object obj)

Description copied from interface: ResourceHandler

Must be implemented to avoid loading the same resource multiple times.

When the same component is used multiple times in a page and that component needs an external resource such as a script, multiple calls will be made to the AddResource methods for the same resource. The AddResource class will create an instance of this class for each such call. However if there is already a ResourceHandler instance existing which is "equal" to the newly created one then a duplicate will not be queued for output.

equals in class Object

hashCode

public int hashCode()

Description copied from interface: ResourceHandler
