groupcast 1.1.0

Dynamic method broadcasting to groups of objects

Groupcast

The Groupcast library provides a simple interface for managing and interacting with a group of objects as if they were a single entity. It supports method broadcasting, property access, and basic list-like behavior (indexing, iteration, and length).

Features

• Broadcast method calls to all objects in the group.

• Aggregate attribute/property access from all objects.

• Behaves like a list: supports len(), indexing ([]), and iteration.

• Flexible construction: either provide a list of objects directly, or provide input data and a constructor class.

Usage

class Example:
    def __init__(self, x):
        self.x = x
    def double(self):
        return self.x * 2
inputs = [1, 2, 3]
group = groupcast.Group(inputs=inputs, class_=Example) 
print(group.x)
# should result in [1, 2, 3]

print(group.double())
# should result in [2, 4, 6]

print(group[0].x)    #< to only print the value for the first object
# should result in 1

Constructor

Group(inputs=None, class_=None, objects=None)

You can initialize a Group in two ways:

1. Using inputs and class_:

   • Creates a list of objects by passing each element of inputs to the class_ constructor.

2. Using objects directly:

   • Pass in a list of pre-created objects.

If neither objects nor both inputs and class_ are provided, a TypeError is raised.

Attribute Access

When accessing an attribute or method:

• If it's a non-callable (e.g., a property or attribute), a list of values is returned from all objects.

• If it's a method, a new function is returned that will call the method on all objects with the provided arguments and return a list of results.

Example Use Cases

• Managing multiple similar sensor or device objects.

• Group operations on widgets, models, or entities in simulations/games.

• Synchronous control of multiple instances for testing or broadcasting commands.
