Method Details

newInstance

public abstract <T> T newInstance(Class<T> c)
                           throws Exception

Throws:

Exception

checkInstantiable

static String checkInstantiable(Class<?> c)

Check if the class can be instantiated by Unsafe allocator. If the instance has interface or abstract modifiers return an exception message.

Parameters:

c - instance of the class to be checked

Returns:

if instantiable null, else a non-null exception message

assertInstantiable

private static void assertInstantiable(Class<?> c)

Asserts that the class is instantiable. This check should have already occurred in ConstructorConstructor; this check here acts as safeguard since trying to use Unsafe for non-instantiable classes might crash the JVM on some devices.

create

public static UnsafeAllocator create()
