/**
|
|
@brief A container for static variables defined in Templates.
|
|
|
|
This class is only relevant to Template tag authors.
|
|
|
|
When processing a template tag in a AbstractNodeFactory implementation, it
|
|
will sometimes make sense to process arguments to the tag as
|
|
KTextTemplate::Variables. Note that usually they should be processed as
|
|
FilterExpression objects instead.
|
|
|
|
Arguments to the tag can be used to construct Variables, which may then be
|
|
resolved into the objects they represent in the given Context in the render
|
|
stage.
