The Context class holds the context to render a Template with.
Definition: context.h:119
An exception for use when implementing template tags.
Definition: exception.h:85
Base class for all nodes.
Definition: node.h:78
The OutputStream class is used to render templates to a QTextStream.
Definition: outputstream.h:81
The Parser class processes a string template into a tree of nodes.
