## Interface ConstructorExecutor

- All Known Implementing Classes:
    ReflectiveConstructorExecutor

      public interface ConstructorExecutor

  Executors are built by resolvers and can be cached by the infrastructure to repeat an operation quickly without going back to the resolvers. For example, the particular constructor to run on a class may be discovered by the reflection constructor resolver - it will then build a ConstructorExecutor that executes that constructor and the ConstructorExecutor can be reused without needing to go back to the resolver to discover the constructor again.

  They can become stale, and in that case should throw an AccessException - this will cause the infrastructure to go back to the resolvers to ask for a new one.

    - #### execute

          TypedValue execute(EvaluationContext context,
                             Object... arguments)
                      throws AccessException

      Execute a constructor in the specified context using the specified arguments.
      Parameters:
        `context` - the evaluation context in which the command is being executed
        `arguments` - the arguments to the constructor call, should match (in terms of number and type) whatever the command will need to run
      Returns:
        the new object
      Throws:
        `AccessException` - if there is a problem executing the command or the CommandExecutor is no longer valid
