Detailed Description

template<typename T>
struct XrdCl::Fwd< T >

A helper class for forwarding arguments between operations. In practice it's a wrapper around std::shared_ptr using FwdStorage as underlying memory.

• T : type of forwarded value

Member Function Documentation

operator*()

template<typename T >

T& XrdCl::Fwd< T >::operator* ( ) const

inline

Dereferencing operator. Note if Fwd has not been assigned with a value this will trigger an exception

Returns

: reference to the underlying value

Exceptions

std::logic_error

Definition at line 213 of file XrdClFwd.hh.

    {
      if( !bool( this->get()->ptr ) ) throw std::logic_error( "XrdCl::Fwd contains no value!" );
      return *this->get()->ptr;
    }

operator->()

template<typename T >

T* XrdCl::Fwd< T >::operator-> ( ) const

inline

Dereferencing member operator. Note if Fwd has not been assigned with a value this will trigger an exception

Returns

: pointer to the underlying value

Exceptions

std::logic_error

Definition at line 226 of file XrdClFwd.hh.

    {
      if( !bool( this->get()->ptr ) ) throw std::logic_error( "XrdCl::Fwd contains no value!" );
      return this->get()->ptr;
    }

operator=() [1/2]

template<typename T >

Fwd& XrdCl::Fwd< T >::operator= ( const T &  value )

inline

Assignment operator.

Parameters

value

: forwarded value

Exceptions

std::logic_error

Definition at line 188 of file XrdClFwd.hh.

    {
      *this->get() = value;
      return *this;
    }

operator=() [2/2]

template<typename T >

Fwd& XrdCl::Fwd< T >::operator= ( T &&  value )

inline

Move assignment operator.

Parameters

value

: forwarded value

Exceptions

std::logic_error

Definition at line 200 of file XrdClFwd.hh.

    {
      *this->get() = std::move( value );
      return *this;
    }

Valid()

template<typename T >

bool XrdCl::Fwd< T >::Valid ( ) const

inline

Check if it contains a valid value.

Definition at line 235 of file XrdClFwd.hh.

    {
      return bool( this->get()->ptr );
    }
