    • postProcessImperativeFunctionResult

      protected O postProcessImperativeFunctionResult(I rawInputs, Object functionInputs, Object functionResult, SimpleFunctionRegistry.FunctionInvocationWrapper function, com.microsoft.azure.functions.ExecutionContext executionContext)
      Post-processes the result from a non-reactive function invocation before returning it to the Azure runtime. The default behavior is to possibly convert the result.

      Provides a hook for custom function invokers to extend/modify the function results handling.

      Parameters:
      rawInputs - the inputs passed in from the Azure runtime
      functionInputs - the actual inputs used for the function invocation; may be different from the rawInputs
      functionResult - the result from the function invocation
      function - the invoked function
      executionContext - the Azure execution context
      Returns:
      the possibly modified function results

    • postProcessReactiveFunctionResult

      protected O postProcessReactiveFunctionResult(I rawInputs, Object functionInputs, org.reactivestreams.Publisher<?> functionResult, SimpleFunctionRegistry.FunctionInvocationWrapper function, com.microsoft.azure.functions.ExecutionContext executionContext)
      Post-processes the result from a reactive function invocation before returning it to the Azure runtime. The default behavior is to delegate to postProcessMonoFunctionResult(I, java.lang.Object, reactor.core.publisher.Mono<?>, org.springframework.cloud.function.context.catalog.SimpleFunctionRegistry.FunctionInvocationWrapper, com.microsoft.azure.functions.ExecutionContext) or postProcessFluxFunctionResult(I, java.lang.Object, reactor.core.publisher.Flux<?>, org.springframework.cloud.function.context.catalog.SimpleFunctionRegistry.FunctionInvocationWrapper, com.microsoft.azure.functions.ExecutionContext) based on the result type.

      Provides a hook for custom function invokers to extend/modify the function results handling.

      Parameters:
      rawInputs - the inputs passed in from the Azure runtime
      functionInputs - the actual inputs used for the function invocation; may be different from the rawInputs
      functionResult - the result from the function invocation
      function - the invoked function
      executionContext - the Azure execution context
      Returns:
      the possibly modified function results

    • postProcessMonoFunctionResult

      protected O postProcessMonoFunctionResult(I rawInputs, Object functionInputs, reactor.core.publisher.Mono<?> functionResult, SimpleFunctionRegistry.FunctionInvocationWrapper function, com.microsoft.azure.functions.ExecutionContext executionContext)
      Post-processes the Mono result from a reactive function invocation before returning it to the Azure runtime. The default behavior is to Mono.blockOptional() and possibly convert the result.

      Provides a hook for custom function invokers to extend/modify the function results handling.

      Parameters:
      rawInputs - the inputs passed in from the Azure runtime
      functionInputs - the actual inputs used for the function invocation; may be different from the rawInputs
      functionResult - the Mono result from the function invocation
      function - the invoked function
      executionContext - the Azure execution context
      Returns:
      the possibly modified function results

    • postProcessFluxFunctionResult

      protected O postProcessFluxFunctionResult(I rawInputs, Object functionInputs, reactor.core.publisher.Flux<?> functionResult, SimpleFunctionRegistry.FunctionInvocationWrapper function, com.microsoft.azure.functions.ExecutionContext executionContext)
      Post-processes the Flux result from a reactive function invocation before returning it to the Azure runtime. The default behavior is to block and possibly convert the results.

      Provides a hook for custom function invokers to extend/modify the function results handling.

      Parameters:
      rawInputs - the inputs passed in from the Azure runtime
      functionInputs - the actual inputs used for the function invocation; may be different from the rawInputs
      functionResult - the Mono result from the function invocation
      function - the invoked function
      executionContext - the Azure execution context
      Returns:
      the possibly modified function results
