Detailed Description

All Templates are created through the Grantlee::Engine class. A template is created by parsing some text markup passed into the Engine, or by reading it from a file.

Note that Template is actually a typedef for a QSharedPointer<TemplateImpl>, so all of its members should be accessed with operator->().

The result of parsing is a Template object which can be rendered multiple times with multiple different Contexts.

Engine *engine = getEngine();
Template t = engine->newTemplate( "{{ name }} is aged {{ age }}", "simple
template" );
if ( t->error() )
{
// Tokenizing or parsing error, or couldn't find custom tags or filters.
qDebug() << t->errorString();
return;
}
QTextStream textStream( stdout );
OutputStream stream( textStream );
for ( ... )
{
Context c;
// ... c.insert
t->render( stream, c );
if (t->error())
{
// Rendering error.
qDebug() << t->errorString();
}
}

If there is an error in parsing or rendering, the error and errorString methods can be used to check the source of the error.
