Detailed Description

template<class Type, class ComponentType>
class Wizt::VComponentValue< Type, ComponentType >

Todo: Think hard whether tha VComponentValue shouldn't rather refer to VValueType<> instead of an VValue<Type>, because then we can described structures recursively as components of each other

Constructor & Destructor Documentation

◆ VComponentValue()

template<class Type, class ComponentType>

Wizt::VComponentValue< Type, ComponentType >::VComponentValue ( const VComponentValue< Type, ComponentType > & V )

inline

Copy constructor: copies just the value, all reference pointing stuff is not duplicated.

Also, the age of the new object is recent.

References VComponentValue().

Member Function Documentation

◆ getType()

template<class Type, class ComponentType>

const type_info & Wizt::VComponentValue< Type, ComponentType >::getType ( ) const

inlineoverridevirtual

Implement the virtual function to query the type ID of this value.

For this value, the type is fixed throughout its lifetime and corresponds to the type of the template argument.

Implements Wizt::VValueBase.

◆ getValue()

template<class Type, class ComponentType>

bool Wizt::VComponentValue< Type, ComponentType >::getValue ( ComponentType & Variable ) const

inlineoverridevirtual

Implement the virtual function to get the current value.

Returns: True on successfull retrieval, which is always the case in the default implementation of a stored value. However, derived values which implement a procedural value might return false here as well.

Parameters

Variable The external storage space where to assign this value.

Implements Wizt::VTypedValueBase< ComponentType >.

◆ request()

template<class Type, class ComponentType>

bool Wizt::VComponentValue< Type, ComponentType >::request	(	const VRequest &	theRequest,
		double	precision )

inlineoverride

Ask to fullfill a request in a certain precision.

By default, this function does nothing, since the value to be computed is already stored here. However, since the function is virtual, a derived class might perform some actions here to compute the requested value.

Parameters

precision A quality parameter in the range [0,1]. Lower values indicate that this function should return as fast as possible, while higher values indicate that accuracy is more important than execution time. With a value of 0.0, the function should return immediately, at 1.0 it should take as long as required to perform the requested operation as accurate as possible.

◆ setValue()

template<class Type, class ComponentType>

bool Wizt::VComponentValue< Type, ComponentType >::setValue ( const ComponentType & Variable )

inlineoverridevirtual

Implement the assignment of the current value.

Parameters

Variable The external storage space from where to assign this value.

Implements Wizt::VTypedValueBase< ComponentType >.

Referenced by setValueFromText().
