** Place on component classes to explicitly use a named template file.
** By default, 'efanXtra' looks for an efan template with the same name as the component class.
@FacetMeta { inherited = true }
facet class TemplateLocation {
** Use to explicitly set the location of the efan template. The Url may take several forms:
** - if fully qualified, the template is resolved, e.g. 'fan://acmePod/templates/Notice.efan'
** - if relative, the template is assumed to be on the file system, e.g. 'etc/templates/Notice.efan'
** - if absolute, the template is assumed to be a pod resource, e.g. '/templates/Notice.efan'
const Uri? url
}
** Place on 'abstract' base components to tell 'efanExta' not to treat it as a component. Example:
**
** syntax: fantom
**
** using afEfanExtra
**
** @Abstract
** const mixin MyComponent : EfanComponent { ... }
**
** Because components are mixins, 'efanXtra' has no other way to differentiate between real components and base classes!
facet class Abstract { }
** Use to mark a component lifecycle method. Init render methods may take any number of parameters. Example:
**
** syntax: fantom
**
** @InitRender
** Bool? initRender(Str x, Int y) { ... }
**
** Param types may be nullable.
facet class InitRender { }
** Use to mark a component lifecycle method.
** Before render methods may optionally define a 'StrBuf' parameter.
** You can use this to change any part of the current rendering.
**
** syntax: fantom
**
** @BeforeRender
** Bool? beforeRender(StrBuf output) { ... }
**
** If the method returns 'false' then rendering is skipped and '@AfterRender' is called.
facet class BeforeRender { }
** Use to mark a component lifecycle method.
** After render methods may optionally define a 'StrBuf' parameter.
** You can use this to change any part of the current rendering.
**
** syntax: fantom
**
** @AfterRender
** Bool? afterRender(StrBuf output) { ... }
**
** If the method returns 'false' then the lifecyle returns back to '@BeforeRender'.
facet class AfterRender { }
