virtual bool epics::pvAccess::ChannelProviderRegistry::add	(	const ChannelProviderFactory::shared_pointer &	fact,
		bool	replace = `true`
	)

virtual

Add new factory.

if replace=false and name already in use, return false with no change in other cases insert provided factory and return true.

ChannelProviderFactory::shared_pointer epics::pvAccess::ChannelProviderRegistry::addSingleton	(	const ChannelProvider::shared_pointer &	provider,
		bool	replace = `true`
	)

Add a pre-created Provider instance.

Only a weak ref to this instance is kept, so the instance must be kept active through some external means

Since: 6.1.0

static ChannelProviderRegistry::shared_pointer epics::pvAccess::ChannelProviderRegistry::clients ( )

static

The global registry for "clients".

Register providers which will be used within this process. Typically providers which access data outside of the process. Associated with EPICS_PVA_PROVIDER_NAMES

ChannelProvider::shared_pointer epics::pvAccess::ChannelProviderRegistry::createProvider	(	std::string const &	providerName,
		const std::tr1::shared_ptr< Configuration > &	conf = `std::tr1::shared_ptr< Configuration >()`
	)

Creates a new instanceof the provider with the specified name.

Parameters

providerName The name of the provider.

Returns: The interface for the provider or null if the provider is not known.

virtual ChannelProviderFactory::shared_pointer epics::pvAccess::ChannelProviderRegistry::getFactory ( std::string const & providerName )

virtual

Fetch provider factor with the specified name.

Parameters

providerName The name of the provider.

Returns: The factor or null if the provider is not known.

ChannelProvider::shared_pointer epics::pvAccess::ChannelProviderRegistry::getProvider ( std::string const & providerName )

Get a shared instance of the provider with the specified name.

Parameters

providerName The name of the provider.

Returns: The interface for the provider or null if the provider is not known.

static ChannelProviderRegistry::shared_pointer epics::pvAccess::ChannelProviderRegistry::servers ( )

static

The global registry for "servers".

Register providers which will be used outside of this process (via ServerContext). Typically providers which access data within the process. Associated with EPICS_PVAS_PROVIDER_NAMES
