TemplateIteratorProvider deprecated
interface TemplateIteratorProvider (View source)
deprecated
Interface that is implemented by any classes that want to expose a method that can be called in any scope in a template that returns values dependent on the state of the iterator of the current scope.
SSViewer_BasicIteratorSupport is an example of this. See also @TemplateGlobalProvider
Methods
Called by SSViewer to get a list of iterator variables to expose to the template, the instance method to call on an instance of this class to get the value for those variables, and the class to use for casting the returned value for use in a template
Set the current iterator properties - where we are on the iterator.
Details
static array
get_template_iterator_variables()
Called by SSViewer to get a list of iterator variables to expose to the template, the instance method to call on an instance of this class to get the value for those variables, and the class to use for casting the returned value for use in a template
If the method to call is not included for a particular template variable, a method named the same as the template variable will be called
If the casting class is not specified for a particular template variable, ViewableData::$default_cast is used
The first letter of the template variable is case-insensitive. However the method name is always case sensitive.
iteratorProperties(int $pos, int $totalItems)
Set the current iterator properties - where we are on the iterator.
This is called by SSViewer prior to calling any of the variables exposed to the template (that is, as returned from a call to get_template_iterator_variables)
