A base class that defines an interface and implements some fundamental methods of a descendant class that 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. More...

◆ GetTypeCode()

virtual TypeCode System::BoxedValueBase::GetTypeCode ( ) const

pure virtual

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

Implemented in System::BoxedValue< T >, and System::BoxedValue< typename std::underlying_type< E >::type >.

◆ GetUnsignedLongLongValue()

virtual uint64_t System::BoxedValueBase::GetUnsignedLongLongValue ( ) const

pure virtual

Converts the boxed represented by the current object to 64-bit integer value.

Returns: 64-bit integer value equivalent to the boxed value represented by the current object

Implemented in System::BoxedEnum< E, UT >, System::BoxedValue< T >, and System::BoxedValue< typename std::underlying_type< E >::type >.

◆ IsBoxedEnum()

virtual bool System::BoxedValueBase::IsBoxedEnum ( )

pure virtual

Determines if current object represents a boxed value of enum type.

Returns: True if current object represents a boxed value of enum type, otherwise - false

Implemented in System::BoxedEnum< E, UT >, System::BoxedValue< T >, and System::BoxedValue< typename std::underlying_type< E >::type >.

◆ Parse() [1/2]

static SharedPtr< Object > System::BoxedValueBase::Parse	(	const TypeInfo &	type,
		const String &	str
	)

static

Boxes the value of enumeration constant of the specified enumeration with the specified name.

Parameters

type	Specifies the type of the enumeration
str	The name of the enumeration constant, value of which is to be boxed

Returns: A shared pointer to the object representing boxed value of the specified enumeration constant

Exceptions

InvalidEnumArgumentException If the specified enumeration constant was not found in the specified enumeration

◆ Parse() [2/2]

static SharedPtr< Object > System::BoxedValueBase::Parse	(	const TypeInfo &	type,
		const String &	str,
		bool	ignoreCase
	)

static

Boxes the value of enumeration constant of the specified enumeration with the specified name. A parameter specifies if the case should be ignored when interpreting the string specifying the name of the enumeration constant.

Parameters

type	Specifies the type of the enumeration
str	The name of the enumeration constant, value of which is to be boxed
ignoreCase	Specifies if case should be ignored when interpreting the string representing the name of the enumeration constant

Returns: A shared pointer to the object representing boxed value of the specified enumeration constant

Exceptions

InvalidEnumArgumentException If the specified enumeration constant was not found in the specified enumeration

◆ ToString() [1/2]

virtual String System::Object::ToString ( ) const

virtual

Analog of C# Object.ToString() method. Enables converting custom objects to string.

Returns: String representation as provided by final class.

Reimplemented from System::Object.

Reimplemented in System::BoxedValue< typename std::underlying_type< E >::type >.

◆ ToString() [2/2]
