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.

auto engine = getEngine();
auto 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.

◆ engine()

Engine const* Grantlee::Template::engine ( ) const

Returns the Engine that created this Template.

◆ error()

Error Grantlee::Template::error ( ) const

Returns an error code for the error encountered.

◆ errorString()

QString Grantlee::Template::errorString ( ) const

Returns more information to developers in the form of a string.

◆ render() [1/2]

QString Grantlee::Template::render ( Context * c ) const

Renders the Template to a string given the Context c.

◆ render() [2/2]

OutputStream* Grantlee::Template::render	(	OutputStream *	stream,
		Context *	c
	)		const
