Interface BotArgumentResolver

public interface BotArgumentResolver
Strategy interface for resolving individual handler method parameters from the current request context. Each implementation handles a specific parameter type or annotation (e.g., injecting the current Update or a custom value extracted from the incoming message). The framework queries all registered resolvers via supportsParameter(Parameter) and delegates to the first matching resolver's resolveArgument(Parameter, BotRequest, BotResponse) to obtain the value.

    • supportsParameter

      boolean supportsParameter(Parameter parameter)
      Determines whether this resolver can provide a value for the given method parameter.
      Parameters:
      parameter - the method parameter to evaluate; must not be null
      Returns:
      true if this resolver can resolve the parameter, false otherwise

    • resolveArgument

      Object resolveArgument(Parameter parameter, BotRequest botRequest, BotResponse botResponse)
      Resolves and returns the argument value to be injected for the given method parameter. Called only when supportsParameter(Parameter) returned true.
      Parameters:
      parameter - the method parameter for which an argument is needed; must not be null
      botRequest - the current request context providing access to the update and client; must not be null
      botResponse - the mutable response object for the current request; must not be null
      Returns:
      the resolved argument value, or null if the parameter is optional and not present
