 Exception (Error errorCode, const QString &what)

Detailed Description

The exception class can be used when implementing AbstractNodeFactory::getNode. An exception can be thrown to indicate that the syntax of a particular tag is invalid.

For example, the following template markup should throw an error because the include tag should have exactly one argument:

{% include %}

The corresponding implementation of IncludeNodeFactory::getNode is

QStringList tagContents = smartSplit( tagContent );
if ( tagContents.size() != 2 )
throw Grantlee::Exception( TagSyntaxError, "Error: Include tag takes
exactly one argument" );
// The item at index 0 in the list is the tag name, "include"
QString includeName = 1 );
