Interface ParameterNameDiscoverer

All Known Implementing Classes:
AspectJAdviceParameterNameDiscoverer, LocalVariableTableParameterNameDiscoverer, PrioritizedParameterNameDiscoverer

public interface ParameterNameDiscoverer

Interface to discover parameter names for methods and constructors.

Parameter name discovery is not always possible, but various strategies are available to try, such as looking for debug information that may have been emitted at compile time, and looking for argname annotation values optionally accompanying AspectJ annotated methods.
