org.zkoss.zk.ui.metainfo.HeaderInfo

public class HeaderInfo
extends Object

Represents a header element, such as <?link> and <?meta> directives on the ZUML page. They are usually represented as directives in ZUML. For example, the link and meta directives represent <link> and <meta> HTML tags, respectively.

Notice

• Directives are evaluated before all other tags. Thus, it is not possible to set a value in zscript and then reference it in an attribute of the directive.
• If a page is included by another page with the instant mode (Include.getMode()), the directives will be ignored.
• EL is allowed for every attribute.
• Since 5.0.0, the if and unless attributes are supported.

It is not serializable.
