- All Implemented Interfaces:
ParameterNameDiscoverer
public class KotlinReflectionParameterNameDiscoverer extends Object implements ParameterNameDiscoverer
ParameterNameDiscoverer
implementation which uses Kotlin's reflection facilities for introspecting parameter names. Compared toStandardReflectionParameterNameDiscoverer
, it allows in addition to determine interface parameter names without requiring Java 8 -parameters compiler flag.- Since:

getParameterNames
@Nullable public String[] getParameterNames(Method method)
Description copied from interface:ParameterNameDiscoverer
Return parameter names for a method, ornull
if they cannot be determined.Individual entries in the array may be
null
if parameter names are only available for some parameters of the given method but not for others. However, it is recommended to use stub parameter names instead wherever feasible.- Specified by:
getParameterNames
in interfaceParameterNameDiscoverer
- Parameters:
method
- the method to find parameter names for- Returns:
- an array of parameter names if the names can be resolved, or
null
if they cannot
