The Classes

Singleton (for inheritance)

This class implements a singleton with a static instantiation method.

Example:

class MySingleton(jk_oop.Singleton):

	__slots__ = (
		"value",
	)

	@jk_typing.checkFunctionSignature()
	def __initialize(self, someValue:int):
		print("Initializing MySingleton")
		self.value = someValue
	#

#

Usage:

# first use with initialization
myInst = MySingleton.getInstance(42)

# same use later
myInst = MySingleton.getInstance()

SingletonMeta (as metaclass)

This class implements a singleton. Initialization is done via constructor.

Example:

class MySingleton(metaclass=jk_oop.SingletonMeta):

	__slots__ = (
		"value",
	)

	@jk_typing.checkFunctionSignature()
	def __init__(self, someValue:int):
		print("Initializing MySingleton")
		self.value = someValue
	#

#

Usage:

# first use with initialization
myInst = MySingleton(42)

# same use later
myInst = MySingleton()
