Class HeaderInfo

  • public class HeaderInfo
    extends java.lang.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.


    • 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.
