What are the differences between ui:composition
and ui:decorate
in Facelets ? Both seem to support ui:define
as child tags . In what cases would you use each of these ?
推荐答案
以外的任何东西< ui:composition>
标记被忽略。对于< ui:decorate>
,情况并非如此,因此这对模板中的模板很有用。
Anything outside <ui:composition>
tag is disregarded. This isn't true for <ui:decorate>
, which is thus beneficial as "template-in-template".
