Method Detail

getAllSuperclasses
public static java.util.List<java.lang.Class<?>> getAllSuperclasses(java.lang.Class<?> cls)
Gets a
List
of superclasses for the given class.- Parameters:
cls
- the class to look up, may benull
- Returns:
- the
List
of superclasses in order going up from this onenull
if null input
-
getAllInterfaces
public static java.util.List<java.lang.Class<?>> getAllInterfaces(java.lang.Class<?> cls)
Gets a
List
of all interfaces implemented by the given class and its superclasses.The order is determined by looking through each interface in turn as declared in the source file and following its hierarchy up. Then each superclass is considered in the same way. Later duplicates are ignored, so the order is maintained.
- Parameters:
cls
- the class to look up, may benull
- Returns:
- the
List
of interfaces in order,null
if null input
-
getAllInterfaces
static void getAllInterfaces(java.lang.Class<?> cls, java.util.HashSet<java.lang.Class<?>> interfacesFound)
Get the interfaces for the specified class.- Parameters:
cls
- the class to look up, may benull
interfacesFound
- theSet
of interfaces for the class
-
isPrimitiveOrWrapper
public static boolean isPrimitiveOrWrapper(java.lang.Class<?> type)
Returns whether the giventype
is a primitive or primitive wrapper (Boolean
,Byte
,Character
,Short
,Integer
,Long
,Double
,Float
,Void
).Returns false if passed null since the method can't evaluate the class.

-
isOptionalOrPrimitiveOptional
public static boolean isOptionalOrPrimitiveOptional(java.lang.Class<?> type)
Returns whether the giventype
is a primitive or primitive wrapper (Optional
,OptionalInt
,OptionalLong
,OptionalDouble
).Returns false if passed null since the method can't evaluate the class.
- Parameters:

isInJavaLangPackage
public static boolean isInJavaLangPackage(java.lang.Class<?> type)
Returns whether the giventype
belongs to the java.lang package itself or one of its subpackage.- Parameters:
type
- The class to check or null.- Returns:
- true the given
type
belongs to the java.lang package itself or one of its subpackage, false otherwise. - Since:
