Class BindableFunctionProxyFactory

java.lang.Object
org.springframework.cloud.stream.binding.AbstractBindableProxyFactory
org.springframework.cloud.stream.binding.BindableProxyFactory
org.springframework.cloud.stream.function.BindableFunctionProxyFactory
All Implemented Interfaces:
org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.FactoryBean<Object>, org.springframework.beans.factory.InitializingBean, Bindable, org.springframework.context.ApplicationContextAware
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`.
