morpheus.utils.execution_chain.ExecutionChain

class ExecutionChain(function_chain=None)

Bases: object

A class that represents a chain of functions to be executed sequentially.

Attributes:

functionsList[Callable]

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)

Adds a function to the chain at a specified position. Default is end of the chain.

Parameters:

functionCallable

The function to add to the chain.

positionint, optional

The position in the chain to add the function to, by default -1 which corresponds to the end of the chain.

remove_function(function)

Removes a specific function from the chain.

Parameters:

functionCallable

The function to remove from the chain.

replace_function(old_function, new_function)

Replaces a specific function in the chain with a new one.

Parameters:

old_functionCallable

The function to be replaced.

new_functionCallable

The function to replace the old one.

validate_chain()

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.
