Method Detail

unboxSafely

public static boolean unboxSafely(java.lang.Boolean ref,
                                  boolean valueIfNull)

getPrimitiveType

public static Maybe<java.lang.Class<?>> getPrimitiveType(java.lang.String typeName)

Returns the unboxed type for the given primitive type name, if available; e.g. Integer.TYPE for int (distinct from Integer.class), or null if not a primitive.

getPrimitiveName

public static Maybe<java.lang.String> getPrimitiveName(java.lang.Class<?> type)

returns name of primitive corresponding to the given (boxed or unboxed) type

boxedType

public static java.lang.Class<?> boxedType(java.lang.Class<?> type)

boxedTypeToken

public static <any> boxedTypeToken(java.lang.reflect.Type type)

isPrimitiveOrBoxedObject

public static boolean isPrimitiveOrBoxedObject(java.lang.Object o)

isPrimitiveOrBoxedClass

public static boolean isPrimitiveOrBoxedClass(java.lang.Class<?> t)

setInArray

public static void setInArray(java.lang.Object target,
                              int index,
                              java.lang.Object value,
                              java.lang.Class<?> type)

sets the given element in an array to the indicated value; if the type is a primitive type, the appropriate primitive method is used

this is needed because arrays do not deal with autoboxing
