class ait.core.server.handler.Handler(input_type=None, output_type=None, **kwargs)

__init__(input_type=None, output_type=None, **kwargs)

Params:

input_type: (optional) Specifies expected input type, used to

validate handler workflow. Defaults to None.

output_type: (optional) Specifies expected output type, used to

validate handler workflow. Defaults to None

**kwargs: (optional) Requirements dependent on child class.

handle(input_data)

be the message received by the stream. Otherwise it will be the output of the previous handler.
