ResourcesFactory

class ResourcesFactory

A Singleton class designed to provide Simulation related objects.

DftResourceName

the default resource file name

DftResourcePriority

priority for the default resource

findObjectClass(absolute_name)

Obtain the class object corresponding to the given name.

Parameter:absolute_name (str) – the object absolute name string Return type:tau.core.TauModel Returns:a class object that should be a subclass of a tau.core.TauModel Raise:(tau.core.TauException) if the given name is invalid.

getAttribute(alias)

Obtain the object corresponding to the given attribute name. If the corresponding attribute already exists, the existing instance is returned. Otherwise a new instance is stored and returned.

Parameter:alias (str) – attribute name string alias Return type:tau.core.TauAttribute Returns:attribute object Raise:(NameError) if the alias does not exist Raise:(tau.core.TauException) if the given alias is invalid.

getConfiguration(alias)

Obtain the object corresponding to the given attribute or full name. If the corresponding configuration already exists, the existing instance is returned. Otherwise a new instance is stored and returned.

Parameter:alias (str) – configuration name string alias Return type:tau.core.TauConfiguration Returns:configuration object Raise:(NameError) if the alias does not exist Raise:(tau.core.TauException) if the given alias is invalid.

getDatabase(alias=None)

Obtain the object corresponding to the given database name or the default database if db_name is None. If the corresponding database object already exists, the existing instance is returned. Otherwise a new instance is stored and returned.

Parameter:alias (str) – database name string alias. If None, the default database is used Return type:tau.core.TauDatabase Returns:database object Raise:(NameError) if the alias does not exist Raise:(tau.core.TauException) if the given alias is invalid.

getDevice(alias)

Obtain the object corresponding to the given device name. If the corresponding device already exists, the existing instance is returned. Otherwise a new instance is stored and returned.

Parameter:alias – device name string alias. Return type:tau.core.TauDevice Returns:device object Raise:(NameError) if the alias does not exist Raise:(tau.core.TauException) if the given alias is invalid.

getValue(key)

Returns the value for a given key

Parameter:key (str) – a key Return type:str Returns:the value for the given key

init(*args, **kwargs)

Singleton instance initialization. For internal usage only

loadResource(obj=None, priority=1, name=None)

(Re)Loads the given resource.

Parameters:

• obj (dict or file or None) – the resource object. Default is None meaning in will (re)load the default resource: tau_resources.py from the application directory
• priority (int) – the resource priority. Default is 1 meaning maximum priority
• name (str) – an optional name to give to the resource

Return type:

dict

Returns:

a dictionary version of the given resource object

reloadResource(obj=None, priority=1, name=None)

(Re)Loads the given resource.

Parameters:

• obj (dict or file or None) – the resource object. Default is None meaning in will (re)load the default resource: tau_resources.py from the application directory
• priority (int) – the resource priority. Default is 1 meaning maximum priority
• name (str) – an optional name to give to the resource

Return type:

dict

Returns:

a dictionary version of the given resource object
