FunctionTable Struct Reference

Description:

This struct is used internally with ALib Boxing to provide run-time 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 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 * 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 127 of file vtable.cpp.

Set()

template<typename TFDecl >

void 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 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 143 of file vtable.cpp.

Shutdown()

void Shutdown ( )

static

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

Definition at line 115 of file vtable.cpp.
