Detailed Description

Field encapsulates a value-field for LazyCondition.

This class acts as a generic container for LazyConditions. You usually don't use it explicitly, but instead use the already defined methods to create instances of this class.

Member Enumeration Documentation

enum Nuria::Field::Type

Field types.

Enumerator
Empty	Empty, invalid field.
Value	Value field. See also val
Argument	Argument reference, the value will be of type int. See also arg
TestCall	A call to a named method. To be defined by the evaluator.
Custom	A custom type used in domain-specific environments, like references to table columns. This acts as a base value, users of this features should try to use unique type values. Example: enum { MyField = Nuria::Field::Custom + 1 };

Constructor & Destructor Documentation

Nuria::Field::Field

(

)

Creates a instance of type Empty.

Nuria::Field::Field	(	int	type,
		const QVariant &	data
	)

Creates a instance of with value data.

Nuria::Field::Field

(

const Field &

other

)

Copy constructor.

Member Function Documentation

int Nuria::Field::customType

(

)

const

Returns the custom type id if this is a custom type, or the regular type.

QVariant Nuria::Field::toVariant

(

)

const

Puts this instance into a QVariant. If the type of this instance is of Empty or Value, the value itself will be returned. Else this instance will be put into a QVariant and then returned.

Type Nuria::Field::type

(

)

const

Returns the type of this instance. If this is a custom instance, Custom will be returned.

customType

const QVariant& Nuria::Field::value

(

)

const

Returns the value of this instance.
