Modifier and Type	Method and Description
static Optional<Object>	createObject(Class c) Try any available public constructors to create an object.
static Class<?>	getCollectionComponentType(Field field) Determine if the field is a list or array and return its component type if so.
static Optional<Object>	getDeclaredValue(AccessibleObject field) Determine the declared (default) value of a field; if a method is provided then an Empty optional is returned Note: This assumes that there is a public no-parameter constructor for the declaring object, otherwise this will return an empty optional.
static boolean	hasMultipleValues(Class clazz) Figure out if field represents multiple values
static boolean	isPrimitive(Field field) A primitive field is one which is a single or array/list of primitive values.

Method Detail

hasMultipleValues

public static boolean hasMultipleValues(Class clazz)

Figure out if field represents multiple values

Parameters:

clazz - Field to evaluate

Returns:

true if field is an array or collection

getCollectionComponentType

public static Class<?> getCollectionComponentType(Field field)

Determine if the field is a list or array and return its component type if so.

Parameters:

field - Field to evaluate

Returns:

List/Array component type or field type if not a list or array

isPrimitive

public static boolean isPrimitive(Field field)

A primitive field is one which is a single or array/list of primitive values.

Parameters:

field - Field to evaluate

Returns:

true if primitive or list/array of primitive values

isSimple

public static boolean isSimple(Field field)

A simple field is either primitive, an enumeration, or a string.

Parameters:

field - Field to evaluate

Returns:

true if primitive, an enumeration, or a string

createObject

public static Optional<Object> createObject(Class c)

Try any available public constructors to create an object. Return the first successful attempt.

Parameters:

c - Class to use

Returns:

Optional object if successful, otherwise empty optional.

getDeclaredValue

public static Optional<Object> getDeclaredValue(AccessibleObject field)

Determine the declared (default) value of a field; if a method is provided then an Empty optional is returned Note: This assumes that there is a public no-parameter constructor for the declaring object, otherwise this will return an empty optional.

Parameters:

field - Field to evaluate
