class layout

parseClass

public static ClassLayout parseClass(Class<?> klass,
                                     Layouter layouter)

Produce the class layout for the given class, and given layouter. Note: You can use this method to cache the introspection results for a constant-sized objects, e.g. plain Java objects. It is not recommended to use this method on arrays, since their lengths differ from instance to instance.

Parameters:

klass - class to work on

layouter - class layouter

Returns:

class layout

create

public static ClassLayout create(org.openjdk.jol.info.ClassData classData,
                                 SortedSet<FieldLayout> fields,
