Interface BoundExecutable<T,R>

Type Parameters:

T -

R -

All Superinterfaces:

AnnotationMetadataProvider, AnnotationSource, Executable<T,R>

public interface BoundExecutable<T,R>
extends Executable<T,R>

A bound Executable is an executable who argument values have been pre-bound to values using a ArgumentBinderRegistry. Unlike a normal Executable zero arguments are expected and an exception will be thrown if the underlying target Executable cannot be invoked with the current state
