public abstract class ComposableDocRouter extends Object implements DocRouter
A Composable DocRouter is a document router that can be used standalone or nested in a primary-fallback composite document routing strategy. The main reason why we need this marker supertype is because the return value is different depending on how the document router is used:
  • Standalone or leaf in a primary-fallback chain: the method will return true (node accepted) or false (node not accepted)
  • Primary routing strategy in a composite primary-fallback chain: the method will return true/false if the node is accepted/refused and null if a failure is met. In this way the DocRouterWithFallback can route the request to the fallback strategy.

      Properly handles the return value of this doc router. The return value is different depending on how the document router is used:
      • Standalone or leaf in a primary-fallback chain: the method will return true (node accepted) or false (node not accepted)
      • Primary routing strategy in a composite primary-fallback chain: the method will return true/false if the node is accepted/refused and null if a failure is met. In this way the DocRouterWithFallback can route the request to the fallback strategy.
      Returns:
      true/false or true/exception depending on the active mode of this router.
