public class MethodArgumentsUberspector
extends org.apache.velocity.util.introspection.AbstractChainableUberspector
implements org.apache.velocity.util.RuntimeServicesAware

Chainable Velocity Uberspector that tries to convert method arguments to formal parameter types when the passed arguments don't match the method signature. In other words, it looks for a method matching the passed arguments and if none is found then it tries the convert the arguments to match the available method signatures (the available methods with the same name and the same number of parameters but with different parameter types). E.g.:

 $obj.someMethod('VALUE')
 // will forward to
 obj.someMethod(SomeEnum.VALUE)
 // if obj has someMethod(SomeEnum) and not someMethod(String)
