Description:

This struct is used internally with ALib Boxing to provide runtime type information and virtual method invocations to boxed values. A singleton instance of a derived type of this class is attached to each Box. Such derived type is generated using templated derived struct VTable.

Method Details:

◆ Get()

template<typename TFDecl>

TFDecl::Signature alib::boxing::detail::FunctionTable::Get ( bool isInvocation ) const

Receives the function of type TFDecl.

Template Parameters

TFDecl The function type to get.

Parameters

isInvocation If true, the invocation counter is increased. This parameter is defined only in debug-compilations.

Returns: The function found, or nullptr in case it was not defined.

◆ getCustom()

void * alib::boxing::detail::FunctionTable::getCustom	(	const std::type_info &	rtti,
		bool	isInvocation ) const

protected

Non-inline implementation of Get used in the case of non-built-in functions.

Parameters

rtti	The `typeid` of the function to get.
isInvocation	If `true`, the invocation counter is increased. This parameter is defined only in debug-compilations.

Returns: The pointer to the box-function.

Definition at line 67 of file vtable.cpp.

◆ Set()

template<typename TFDecl>

void alib::boxing::detail::FunctionTable::Set ( typename TFDecl::Signature implementation )

Registers an implementation of the function of type TFDecl.

Template Parameters

TFDecl The function type to register.

Parameters

implementation The implementation of the function.

◆ setCustom()

void alib::boxing::detail::FunctionTable::setCustom	(	const std::type_info &	rtti,
		void *	implementation )

protected

Non-inline implementation of Set Get used in the case of non-built-in functions.

Parameters

rtti	The `typeid` of the function to register.
implementation	The implementation of the function.

Definition at line 81 of file vtable.cpp.

◆ Shutdown()

void alib::boxing::detail::FunctionTable::Shutdown ( )

static

Needs to be called only in debug versions to shut down internal hashtables cleanly.

Definition at line 56 of file vtable.cpp.
