All Implemented Interfaces:

public class BindableFunctionProxyFactory
extends BindableProxyFactory
implements org.springframework.context.ApplicationContextAware

FactoryBean for creating inputs/outputs destinations to be bound to function arguments. It is an extension to BindableProxyFactory which operates on Bindable interfaces (e.g., Source, Processor, Sink) which internally define inputs and output channels. Unlike BindableProxyFactory, this class operates based on the count of provided inputs and outputs deriving the binding (channel) names based on convention - `<function-definition>. + <in/out> + .<index>`
For example, `myFunction.in.0` - is the binding for the first input argument of the function with the name `myFunction`.
