Interface ParameterNameDiscoverer
- All Known Implementing Classes:
AspectJAdviceParameterNameDiscoverer
,DefaultParameterNameDiscoverer
,KotlinReflectionParameterNameDiscoverer
,PrioritizedParameterNameDiscoverer
,StandardReflectionParameterNameDiscoverer
Parameter name discovery is not always possible, but various strategies exist
— for example, using the JDK's reflection facilities for introspecting
parameter names (based on the "-parameters" compiler flag), looking for
argNames
annotation attributes optionally configured for AspectJ
annotated methods, etc.

Method Details

getParameterNames
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.- 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
