#include <genericdata.h>

Detailed Description

GenericData wraps an object of arbitary type. Therefore it's similar to Data, but it supports less operations:

GenericData can be moved, but it can't be copied.
The destructor of the wrapped object is called properly.
You can obtain the wrapped object with Get, but you have to know it's exact type at compile-time.
You can't query the type at runtime.

The advantage is that you don't need to register the type of the wrapped object as a DataType.

Constructor & Destructor Documentation

◆ GenericData() [1/2]

GenericData ( )

default

Constructs an empty GenericData.

◆ GenericData() [2/2]

GenericData ( GenericData && src )

Constructs a GenericData by moving the contents of src to the new GenericData. src will be an empty GenericData afterwards.

Parameters

[in,out] src The source object.

◆ ~GenericData()

~GenericData ( )

Destructs this GenericData. This frees any previously set value.

Member Function Documentation

◆ MAXON_OPERATOR_MOVE_ASSIGNMENT()

MAXON_OPERATOR_MOVE_ASSIGNMENT ( GenericData )

◆ Reset()

void Reset ( )

Resets this GenericData to an empty object. This frees any previously set value.

◆ Set()

Result<void> Set ( T && value )

Initializes this GenericData with value. This frees any previously set value at first.

Parameters

[in] value The value to wrap.

Returns: OK on success.

◆ IsEmpty()

Bool IsEmpty ( ) const

Checks if this GenericData is empty.

Returns: True if this GenericData has no wrapped value, false otherwise.

◆ IsPopulated()

Bool IsPopulated ( ) const

Checks if this GenericData has a wrapped value.

Returns: True if this GenericData has a wrapped value, false otherwise.

◆ Get() [1/2]

const T& Get ( ) const

Returns the wrapped value. The type T has to match the exact type of the wrapped value, otherwise the behaviour is undetermined. There is no check that the type matches.

Template Parameters

T	The type of the wrapped value.

Returns: The wrapped value of type T.

◆ Get() [2/2]

T& Get ( )

Returns the wrapped value. The type T has to match the exact type of the wrapped value, otherwise the behaviour is undetermined. There is no check that the type matches.

Template Parameters

T	The type of the wrapped value.

Returns: The wrapped value of type T.

◆ GetPointer() [1/2]

const void* GetPointer ( ) const

Returns a pointer to the wrapped value.

Returns: Pointer to the wrapped values.

◆ GetPointer() [2/2]

void* GetPointer ( )

Returns a pointer to the wrapped value.

Returns: Pointer to the wrapped values.

◆ Free()

static void Free ( GenericData * v )
