list - the original listparameterType - the resulting array typenote: when shifting with 32 bit, you should only shift on a long. If you do that with an int, then i==(i<<32), which means you loose the shift information
In general we want to match the signature that allows us to use
as less arguments for the vargs part as possible. That means the
longer signature usually wins if both signatures are vargs, while
vargs looses always against a signature without vargs.
A vs B :
def foo(Object[] a) {1} -> case B
def foo(a,b,Object[] c) {2} -> case A
assert foo(new Object(),new Object()) == 2
--> A preferred over B
A vs C :
def foo(Object[] a) {1} -> case B
def foo(a,b) {2} -> case C
assert foo(new Object(),new Object()) == 2
--> C preferred over A
A vs D :
def foo(Object[] a) {1} -> case D
def foo(a,Object[] b) {2} -> case A
assert foo(new Object()) == 2
--> A preferred over D
This gives C

list - a list of MetaMethodsmethod - the MetaMethod of interestConverts a String into a standard property name.
prop - the original nameparam instance array to the type array
args - the argumentsSets the meta class for an object, by delegating to the appropriate DefaultGroovyMethods helper method. This method was introduced as a breaking change in 2.0 to solve rare cases of stack overflow. See GROOVY-5285. The method is named doSetMetaClass in order to prevent misusages. Do not use this method directly unless you know what you do.
self - the object for which to set the meta classmc - the metaclassReturns a callable object for the given method name on the object. The object acts like a Closure in that it can be called, like a closure and passed around - though really its a method pointer, not a closure per se.
object - the object containing the methodmethodName - the method of interest
