Detailed Description

Represent an immutable meta information value as a type-id and type-erased data.

The MetainfoValueImpl can be implicitly casted to the supported types.

Constructor & Destructor Documentation

◆ MetainfoValueImpl()

template<class ValueType , class DecayedValueType = typename std::decay<ValueType>::type, class PrimitiveType = typename MakePrimitive<DecayedValueType>::type, class = typename std::enable_if< !std::is_same<DecayedValueType, MetainfoValueImpl>::value>::type>

serialbox::MetainfoValueImpl::MetainfoValueImpl ( ValueType && value )

inlineexplicit

Construct with given value.

Template Parameters

ValueType Type of the captured value (needs to be supported)

Parameters

value Value to capture

Definition at line 58 of file MetainfoValueImpl.h.

Member Function Documentation

◆ as()

template<class T >

T serialbox::MetainfoValueImpl::as ( ) const

inline

Convert the value to type T

If the type T is different than the internally stored type, the function does its best to convert the value to T in a meaningful way.

Returns: Copy of the value of the element as type T

Exceptions

Exception Conversion error: Conversion would result in truncation of the value or conversions from primitive to array type

Definition at line 76 of file MetainfoValueImpl.h.

◆ operator T()

template<class T >

serialbox::MetainfoValueImpl::operator T ( ) const

inline

Implicitly convert value to type T
