Class Details

class EBackend.BackendFactory(**kwargs)

Bases:EDataServer.Extension Abstract:Yes Structure:EBackend.BackendFactoryClass

Contains only private data that should be read and manipulated using the functions below.

New in version 3.4.

get_hash_key()

Returns:a hash key which uniquely identifies self Return type:str

Returns a hash key which uniquely identifies self.

Since only one instance of each EBackend.BackendFactory subclass is ever created, the hash key need only be unique among subclasses, not among instances of each subclass.

New in version 3.4.

get_module_filename()

Returns:the filename for the module associated to the self Return type:str

Returns the filename of the shared library for the module used to load the backends provided by self.

New in version 3.16.

new_backend(source)

Parameters:source (EDataServer.Source) – an EDataServer.Source Returns:a new EBackend.Backend instance for source Return type:EBackend.Backend

Returns a new EBackend.Backend instance for source.

New in version 3.4.

share_subprocess()

Returns:True if the self shares the subprocess for all its backends. Otherwise, False. Return type:bool

Returns True if the self wants to share the subprocess for all backends provided by itself. Otherwise, returns False.

New in version 3.16.

do_get_hash_key() virtual

Returns:a hash key which uniquely identifies factory Return type:str

Returns a hash key which uniquely identifies factory.

Since only one instance of each EBackend.BackendFactory subclass is ever created, the hash key need only be unique among subclasses, not among instances of each subclass.

New in version 3.4.

do_new_backend(source) virtual

Parameters:source (EDataServer.Source) – an EDataServer.Source Returns:a new EBackend.Backend instance for source Return type:EBackend.Backend

Returns a new EBackend.Backend instance for source.

New in version 3.4.
