dumpObject

static void dumpObject(StringBuffer sb,
                       Object obj)

findCompatibleConstructor

public static Constructor findCompatibleConstructor(Class cl,
                                                    Object[] oa)
                                             throws NoSuchMethodError

Find a constructor compatible with given objects.

NoSuchMethodError

findCompatibleField

public static Field findCompatibleField(Field[] fa,
                                        String name,
                                        Object paramObject)
                                 throws NoSuchFieldException

Find a field given its name and a compatible object.

NoSuchFieldException

findCompatibleMethod

public static Method findCompatibleMethod(Method[] ma,
                                          String name,
                                          Object[] paramObject)
                                   throws NoSuchMethodException

Find a compatible method by name given its parameter objects.

NoSuchMethodException

getPrimForWrapper

public static Class getPrimForWrapper(Class cl)

Get primitive type for given object class.

getWrapperForPrim

public static Class getWrapperForPrim(Class cl)

Get wrapper class for given primitive type.

isCompatible

public static boolean isCompatible(Class[] paramClass,
                                   Object[] paramObject)

Determine if given objects are compatible with corresponding classes.

isCompatible

public static boolean isCompatible(Class paramClass,
                                   Object paramObject)

Determine if the given object is assignability compatible with the given class. This method also checks for primitive types besides Class.isAssignableFrom.

primitive2ObjectArray

public static Object[] primitive2ObjectArray(Object primitiveArray)

Turn an array of a primitive type into an Object array of corresponding class type.
