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 Grantlee::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.

Constructs an invalid Variable

Creates a Variable represented by the given var

Copy constructor

Destructor
bool Grantlee::Variable::isConstant | ( | ) | const |
Returns whether this Variable is a constant in the Template. A constant is represented as a static string in the template
bool Grantlee::Variable::isLocalized | ( | ) | const |
Returns whether this variable is localized, that is, if it is wrapped with _().
bool Grantlee::Variable::isTrue | ( | Context * | c | ) | const |
Returns whether this Variable evaluates to true with the Context c
.
bool Grantlee::Variable::isValid | ( | ) | const |
Returns whether this Variable is valid.
QVariant Grantlee::Variable::literal | ( | ) | const |
Returns whether this variable is a literal string or number. A literal Variable does not have any lookup components.
QStringList Grantlee::Variable::lookups | ( | ) | const |
Returns the lookup components of this Variable.
