Pyjo.Base is a simple base class for Pyjo projects.

class Pyjo.Base.Pyjo_Base

obj = SubClass.new()
obj = SubClass.new(name='value')

This base class provides a standard constructor for Pyjo objects. You can pass it a dict with attribute values.

classmethod new(*args, **kwargs)

Factory method for Pyjo.Base class.

set(**kwargs)

obj = obj.set(name='value')

Sets each attribute from a dict.

tap(*args, **kwargs)

obj = obj.tap(lambda obj: expression)
obj = obj.tap(method)
obj = obj.tap(method, *args, **kwargs)

K combinator, tap into a method chain to perform operations on an object within the chain. The object will be the first argument passed to the callback.

# Longer version
obj = obj.tap(lambda obj: obj.method(args))

# Inject side effects into a method chain
obj.foo('A').tap(lambda obj: print(obj.foo)).set(foo='B')
