Method Detail

getBaseType

public static Type getBaseType(Field field)

Determine the "base type" of a field. That is, the following will be returned:

• String -> String.class
• Optional<String> -> String.class
• Set<String> -> String.class
• Collection<? extends Comparable> -> Comparable.class
• Collection<? super Comparable -> Object.class

getContainerClass

@Nullable
public static Class<? extends Collection<?>> getContainerClass(Field field)

Returns:

The raw type of the Collection a field represents, even if contained in an Optional, but without the ParameterizedType information.

getFirstNonOptionalType

public static Type getFirstNonOptionalType(Field field)

Get the first complete Type in a signature that's non-optional, complete with the information from the ParameterizedType.

• String -> String
• Optional<String$gt; -> String
• ImmutableSet<String> -> ImmutableSet<String>
• Optional<ImmutableSet<String>> -> ImmutableSet<String>

getSupertypes

public static com.google.common.collect.ImmutableSet<Class<?>> getSupertypes(Class<?> clazz)

Returns a Set of classes and interfaces inherited or implemented by clazz.

Result includes clazz itself. Result is ordered closest to furthest, i.e. first entry will always be clazz and last entry will always be Object.
