Detailed Description

template<class T>
class yarp::os::SharedLibraryClass< T >

Container for an object created using a factory provided by a shared library.

Used to ensure the object is destroyed by a method also provided by the shared library. Mixing creation and destruction methods could be very bad.

Constructor & Destructor Documentation

SharedLibraryClass() [1/2]

template<class T >

yarp::os::SharedLibraryClass< T >::SharedLibraryClass ( )

default

Constructor for empty instance.

SharedLibraryClass() [2/2]

template<class T >

yarp::os::SharedLibraryClass< T >::SharedLibraryClass ( SharedLibraryClassFactory< T > &  factory )

inline

Constructor for valid instance of a class from a shared library.

Parameters

factory

the factory to use to construct (and eventually destroy) the instance.

Definition at line 42 of file SharedLibraryClass.h.

~SharedLibraryClass()

template<class T >

virtual yarp::os::SharedLibraryClass< T >::~SharedLibraryClass ( )

inlinevirtual

Destructor.

Definition at line 90 of file SharedLibraryClass.h.

Member Function Documentation

close()

template<class T >

virtual bool yarp::os::SharedLibraryClass< T >::close ( )

inlinevirtual

Destroy an instance if one has been created.

Returns

true on success

Definition at line 70 of file SharedLibraryClass.h.

getContent() [1/2]

template<class T >

T& yarp::os::SharedLibraryClass< T >::getContent ( )

inline

Gives access to the created instance.

No check made to ensure an instance is in fact present. Call SharedLibraryClass::isValid first if unsure.

Returns

the created instance

Definition at line 103 of file SharedLibraryClass.h.

getContent() [2/2]

template<class T >

const T& yarp::os::SharedLibraryClass< T >::getContent ( ) const

inline

Gives access to the created instance (const version).

No check made to ensure an instance is in fact present. Call SharedLibraryClass::isValid first if unsure.

Returns

the created instance

Definition at line 116 of file SharedLibraryClass.h.

isValid()

template<class T >

bool yarp::os::SharedLibraryClass< T >::isValid ( ) const

inline

Check whether a valid instance has been created.

Returns

true iff a valid instance has been created

Definition at line 126 of file SharedLibraryClass.h.

open()

template<class T >

bool yarp::os::SharedLibraryClass< T >::open ( SharedLibraryClassFactory< T > &  factory )

inline

Construct an instance using the specified factory.

If an instance has already been made, it is destroyed.

Parameters

factory

the factory to use to construct (and eventually destroy) the instance.

Returns

true on success

Definition at line 55 of file SharedLibraryClass.h.

operator*() [1/2]

template<class T >

T& yarp::os::SharedLibraryClass< T >::operator* ( )

inline

Shorthand for SharedLibraryClass::getContent.

Returns

the created instance

Definition at line 136 of file SharedLibraryClass.h.

operator*() [2/2]

template<class T >

const T& yarp::os::SharedLibraryClass< T >::operator* ( ) const

inline

Shorthand for SharedLibraryClass::getContent (const version)

Returns

the created instance

Definition at line 146 of file SharedLibraryClass.h.

operator->() [1/2]

template<class T >

T* yarp::os::SharedLibraryClass< T >::operator-> ( )

inline

A pointer version of SharedLibraryClass::getContent.

Returns

a pointer to the created instance, or nullptr if there is none

Definition at line 157 of file SharedLibraryClass.h.

operator->() [2/2]

template<class T >

const T* yarp::os::SharedLibraryClass< T >::operator-> ( ) const

inline

A pointer version of SharedLibraryClass::getContent (const version)

Returns

a pointer to the created instance, or nullptr if there is none

Definition at line 168 of file SharedLibraryClass.h.
