| asPrimitiveArray | | public static Object asPrimitiveArray(List list, Class parameterType)(Code) | |
Parameters:
list -
Parameters:
parameterType - |
| calculateParameterDistance | | public static long calculateParameterDistance(Class[] arguments, Class[] parameters)(Code) | | |
| chooseEmptyMethodParams | | public static Object chooseEmptyMethodParams(List methods)(Code) | | the method with 1 parameter which takes the most general type ofobject (e.g. Object) |
| chooseMostGeneralMethodWith1NullParam | | public static Object chooseMostGeneralMethodWith1NullParam(List methods)(Code) | | the method with 1 parameter which takes the most general type ofobject (e.g. Object) ignoring primitve types |
| coerceArgumentsToClasses | | public static Object[] coerceArgumentsToClasses(Object[] argumentArray, Class[] paramTypes)(Code) | | |
| coerceGString | | protected static Object coerceGString(Object argument, Class clazz)(Code) | | Coerces a GString instance into String if needed
the coerced argument |
| containsMatchingMethod | | public static boolean containsMatchingMethod(List list, MetaMethod method)(Code) | | true if a method of the same matching prototype was found in thelist |
| convertToTypeArray | | public static Class[] convertToTypeArray(Object[] args)(Code) | | param instance array to the type array
Parameters:
args - |
| createListenerProxy | | public static Object createListenerProxy(Class listenerType, String listenerMethodName, Closure closure)(Code) | |
Parameters:
listenerType - the interface of the listener to proxy
Parameters:
listenerMethodName - the name of the method in the listener API to call theclosure on
Parameters:
closure - the closure to invoke on the listenerMethodName methodinvocation a dynamic proxy which calls the given closure on the givenmethod name |
| getMethodPointer | | public static Closure getMethodPointer(Object object, String methodName)(Code) | | Returns 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.
