Detailed Description

This class is the factory class used to create instances of the IlsMvComponent class.

Library: mvserver
and mvcomp

Any component of a dynamic view server, either distributed or linked, is implemented by an instance of the IlsMvComponent type or of one of its subtypes.

• In distributed applications, such an instance is automatically created on the component side each time this process connects to a dynamic view server (see IlsMvComponent::Connect()).
• In linked mode, such an instance is automatically created as soon as there is an attempt to open a view without specifying any owning component (see IlsMvServer::OpenView()).

By subclassing IlsMvComponentFactory and overriding the newInstance() function, you can create your own subtype of IlsMvComponent.

Constructor & Destructor Documentation

IlsMvComponentFactory()

IlsMvComponentFactory::IlsMvComponentFactory

(

)

Constructor.

The construction of an IlsMvComponentFactory object is triggered either by the function GetSingleton() or by the construction of a subtype object.

~IlsMvComponentFactory()

virtual IlsMvComponentFactory::~IlsMvComponentFactory ( )

virtual

Destructor.

The destruction of the singleton is automatically performed at process exit.

Member Function Documentation

getHostName()

virtual const char* IlsMvComponentFactory::getHostName ( )

virtual

Ysed by Rogue Wave Server when a component connects to a server.

This function returns the name of the host running the component. It can be overridden.

getInetId()

virtual const char* IlsMvComponentFactory::getInetId ( )

virtual

Used by Rogue Wave Server when a component connects to a server.

This function returns the IP address of the host on the Internet. It can be overridden.

getProcessId()

virtual long IlsMvComponentFactory::getProcessId ( )

virtual

Used by Rogue Wave Server when a component connects to a server.

This function returns the component process identifier. It can be overridden.

GetSingleton()

static IlsMvComponentFactory& IlsMvComponentFactory::GetSingleton ( )

static

Returns a reference to the component factory.

If no factory has been declared yet, an instance of IlsMvComponentFactory is automatically created. It is declared as the class singleton using the SetSingleton() member function and returned as the result of this function.

Returns

reference to the component factory singleton

GetSingletonPtr()

static IlsMvComponentFactory* IlsMvComponentFactory::GetSingletonPtr ( )

static

Returns a pointer to the class singleton.

If no singleton has been declared yet, it returns the null pointer.

Returns

a pointer to the component factory singleton

getUserId()

virtual long IlsMvComponentFactory::getUserId ( )

virtual

Used by Rogue Wave Server when a component connects to a server.

This function returns the user identifier. It can be overridden.

getUserInfo()

virtual IlsMvValue* IlsMvComponentFactory::getUserInfo ( int &  argc )

virtual

Called by a Server component when the connection to a server is established.

The function returns an array of IlsMvValue objects which are then assigned to the corresponding IlsMvUser instance on the server side.

See the member functions IlsMvUser::setUserInfo() and IlsMvUser::getUserInfo() for more information. If the returned arrary is not null, Rogue Wave Server deletes it using the system function delete []. The argc parameter must be set to the size of the returned array.

getUserName()

virtual const char* IlsMvComponentFactory::getUserName ( )

virtual

Used by Rogue Wave Server when a component connects to a server.

This function returns the name of the user who started the component. It can be overridden.

Instanciate()

static IlsMvComponent* IlsMvComponentFactory::Instanciate ( )

static

Called by Rogue Wave Server to create a new instance of the IlsMvComponent class.

It calls the newInstance() function on the class singleton (see GetSingleton()).

Returns

a pointer to the new instance

newInstance()

virtual IlsMvComponent* IlsMvComponentFactory::newInstance ( )

virtual

Called by the Instanciate() function on the class singleton to create a new instance of an IlsMvComponent class or subclass.

You must override it if you want Rogue Wave Server to create instances of a specific derived class.

See also

GetSingleton(), Instanciate().

Returns

pointer to the new instance

Reimplemented in IlsSwComponentFactory.

SetSingleton()

static IlsMvComponentFactory* IlsMvComponentFactory::SetSingleton ( IlsMvComponentFactory *  s )

static

Declares the object pointed to by s as the component factory singleton.

If s is null, the component factory singleton no longer exists. This function returns the address of the previous current component factory or, by default, the null pointer.

Parameters

s	pointer to the new singleton

Returns

pointer to the previous singleton
