- class ExecutionChain(function_chain=None)[source]
Bases:
objectA class that represents a chain of functions to be executed sequentially.
- Attributes
- functions
List of functions to be executed in the chain.
Methods
__call__(**kwargs): Executes all the functions in the chain. add_function(function: Callable, position: int = -1): Adds a function to the chain at a specified position. remove_function(function: Callable): Removes a specific function from the chain. replace_function(old_function: Callable, new_function: Callable): Replaces a specific function in the chain with a new one. validate_chain(): Validates the function chain. - add_function(function, position=- 1)[source]
Adds a function to the chain at a specified position. Default is end of the chain.
- Parameters
- function
- position
The function to add to the chain.
The position in the chain to add the function to, by default -1 which corresponds to the end of the chain.
- remove_function(function)[source]
Removes a specific function from the chain.
- Parameters
- function
The function to remove from the chain.
- replace_function(old_function, new_function)[source]
Replaces a specific function in the chain with a new one.
- Parameters
- old_function
- new_function
The function to be replaced.
The function to replace the old one.
- validate_chain()[source]
Validates the function chain by ensuring all objects in the chain are callable and all functions except the last one return a dictionary.
- Raises
- ValueError
If an object in the chain is not callable or a function does not return a dictionary.
