CopyWrapper< T > Class Template Reference

#include <movecopywrapper.h>

Detailed Description

template<typename T>
class maxon::CopyWrapper< T >

This wrapper helps to capture objects which require CopyFrom() in a lambda. The get method will return an error if copying the object into the wrapper failed. Of course move construction and assignment are supported too.

Template Parameters

T

Type of object to wrapped. JobRef EnqueueSendJob(const BaseArray<Char>& jobdata) { return JobRef::Enqueue( [this, copy = CopyWrapper<BaseArray<Char>>(jobdata)]() -> Result<void> { iferr_scope; const BaseArray<Char>& array = copy.Get() iferr_return; return _stream.Write(array.GetFirst(), array.GetCount()); }, _queue); }

Constructor & Destructor Documentation

CopyWrapper() [1/5]

CopyWrapper

(

)

CopyWrapper() [2/5]

CopyWrapper ( const T &  src )

explicit

Copies the source object into the wrapper. Get() will return an error if the copy failed.

Parameters

[in]

src

Object to be copied into the wrapper.

CopyWrapper() [3/5]

CopyWrapper ( T &&  src )

explicit

Moves the source object into the wrapper. Following Get()s will succeed because the move can't fail.

Parameters

[in]

src

Object to be moved into the wrapper.

CopyWrapper() [4/5]

CopyWrapper

(

const CopyWrapper< T > &

src

)

Copies the source wrapper. Get() will return an error if the copy failed.

Parameters

[in]

src

Wrapper to be copied.

CopyWrapper() [5/5]

CopyWrapper

(

CopyWrapper< T > &&

src

)

Moves the source wrapper. Following Get()s will succeed because the move can't fail.

Parameters

[in]

src

Wrapper to be moved.

Member Function Documentation

CopyWrapper& operator=

(

const CopyWrapper< T > &

src

)

Copy assigns the source wrapper. Get() will return an error if the copy failed.

Parameters

[in]

src

Wrapper to be copied.

operator=() [2/2]

CopyWrapper& operator=

(

CopyWrapper< T > &&

src

)

Move assign the source wrapper. Following Get()s will succeed because the move can't fail.

Parameters

[in]

src

Wrapper to be moved.

Get() [1/2]

ResultRef<const T> Get

(

void

)

const

Returns a reference to the wrapped object if the assignment or construction of the wrapper was successful.

Returns

Reference to wrapped object on success, error on failure.

Get() [2/2]

ResultRef<T> Get

(

void

)

Returns a reference to the wrapped object if the assignment or construction of the wrapper was successful.

Returns

Reference to wrapped object on success, error on failure.
