Detailed Description

Holds argument type and value information.

The MethodArgument holds the type and value of a metamethod argument or the return value of the method. You can specify the value of the argument upon instantiation and retrieve it with one of the get() template function members.

Constructor & Destructor Documentation

kanzi::MethodArgument::MethodArgument ( )

explicit

Constructor.

kanzi::MethodArgument::~MethodArgument

(

)

Destructor.

template<typename TDataType >

kanzi::MethodArgument::MethodArgument ( const PropertyType< TDataType > &  argumentType, typename PropertyType< TDataType >::DataType  value  )

inlineexplicit

Creates an argument with a property type.

Parameters

argumentType	A property type defining the type of the argument.
value	The value of the argument.

template<typename TDataType >

kanzi::MethodArgument::MethodArgument ( AbstractPropertyType  argumentType, TDataType  value  )

inlineexplicit

Creates an argument using an AbstractPropertyType.

The type of the value must match the type defined by the argumentType.

Parameters

argumentType	An abstract property type defining the type of the argument.
value	The value of the argument.

kanzi::MethodArgument::MethodArgument ( const MethodArgument &  other )

inline

Copy-constructor.

Member Function Documentation

MethodArgument& kanzi::MethodArgument::operator= ( const MethodArgument &  other )

inline

Assignment operator.

template<typename TDataType >

optional<TDataType> kanzi::MethodArgument::get ( const PropertyType< TDataType > &  argumentType ) const

inline

Returns the value of the argument.

The argumentType must match the type of the MethodArgument instance.

Parameters

argumentType

Type of the argument.

Returns

The value of the argument, or nullopt, if the argument is not valid or the argumentType and the stored type do not match.

template<typename TDataType >

bool kanzi::MethodArgument::get ( AbstractPropertyType  argumentType, TDataType &  value  ) const

inline

Overloaded version of get() using AbstractPropertyType to retrieve the value.

Parameters

argumentType	AbstractPropertyType defining the type of the argument.
value	The address to store the argument value.

Returns

true if the argument can be retrieved, false if the argument is invalid, the argumentType differs from the type stored, or the type of the value differs from the type of the argument.

AbstractPropertyType kanzi::MethodArgument::getType ( ) const

inline

Returns the type of the argument.

bool kanzi::MethodArgument::isValid ( ) const

inline

Returns true if the argument stores a valid value, false otherwise.
