Detailed Description

template<class T>
class System::BoxedValue< T >

Represents a boxed value. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

Template Parameters
TType of the boxed value represented by the class

Constructor & Destructor Documentation

◆ BoxedValue()

template<class T>
System::BoxedValue< T >::BoxedValue ( const T &  value)
inline

Constructs an object that represents the specified value boxed.

Parameters
valueThe value to be boxed

Member Function Documentation

◆ Equals()

template<class T>
bool System::BoxedValue< T >::Equals ( ptr  obj)
inlineoverridevirtual

Determines the equality of the boxed values represented by the current and specified objects.

Parameters
objThe object that represent the boxed value to be compared with the boxed value represented by the current object
Returns
True if the boxed value represented by the current object and obj are equal, otherwise - false

Reimplemented from System::Object.

◆ GetHashCode()

template<class T>
int System::BoxedValue< T >::GetHashCode ( ) const
inlineoverridevirtual

Returns a hash code for the current object.

Reimplemented from System::Object.

◆ GetType()

template<class T>
const System::TypeInfo& System::BoxedValue< T >::GetType ( ) const
inlineoverridevirtual

Gets actual type of object.

Returns
TypeInfo object which describes final type.

Reimplemented from System::Object.

◆ GetTypeCode()

template<class T>
TypeCode System::BoxedValue< T >::GetTypeCode ( ) const
inlineoverridevirtual

Returns the value representing the type of the boxed value represented by the current object.

Returns
Value of TypeCode enum representing the type of the boxed value represented by the current object

Implements System::BoxedValueBase.

◆ GetUnsignedLongLongValue()

template<class T>
uint64_t System::BoxedValue< T >::GetUnsignedLongLongValue ( )
inlineoverridevirtual

Always returns 0.

Implements System::BoxedValueBase.

◆ is()

template<class T>
template<class V >
bool System::BoxedValue< T >::is ( ) const
inline

Determines if the type of the boxed value represented by the current object is V.

Returns
True if the type of the boxed value represented by the current object is V, otherwise - false
Template Parameters
VThe type that is comared with the type of boxed value represented by the current object

◆ IsBoxedEnum()

template<class T>
bool System::BoxedValue< T >::IsBoxedEnum ( )
inlineoverridevirtual

Determines if current object represents a boxed value of enum type

Returns
Always false

Implements System::BoxedValueBase.

◆ ToString()

template<class T>
String System::BoxedValue< T >::ToString ( ) const
inlineoverridevirtual

Converts boxed value represented by current object to string

Returns
String representation of the boxed value represented by current object

Reimplemented from System::Object.

◆ unbox()

template<class T>
const T& System::BoxedValue< T >::unbox ( ) const
inline

Unboxes the value represented by the current object.

Returns
The unboxed value
