Class LocalVariableTableParameterNameDiscoverer
java.lang.Object
   org.springframework.core.LocalVariableTableParameterNameDiscoverer
org.springframework.core.LocalVariableTableParameterNameDiscoverer
- All Implemented Interfaces: 
- ParameterNameDiscoverer
- public class LocalVariableTableParameterNameDiscoverer 
- extends Object- implements ParameterNameDiscoverer
Implementation of ParameterNameDiscoverer that uses the LocalVariableTable
 information in the method attributes to discover parameter names. Returns
 null if the class file was compiled without debug information.
 
Uses ObjectWeb's ASM library for analyzing class files. Each discoverer
 instance caches the ASM ClassReader for each introspected Class, in a
 thread-safe manner. It is recommended to reuse discoverer instances
 as far as possible.
