Each component, page, desktop, session and Web application has an independent map of attributes. It is a good place to share data among components, pages, desktops and even sessions.

In zscript and EL expressions, you could use the implicit objects: componentScope, pageScope, desktopScope, sessionScope, requestScope and applicationoScope.

In a Java class, you could use the attribute-relevant methods in corresponding classes to access them. You could also use the scope argument to identify which scope you want to access. The following two statements are equivalent, assuming comp is a component.

comp.getAttribute("some", comp.DESKTOP_SCOPE);
comp.getDesktop().getAttribute("some");
