Constructor Detail

MutableType

public MutableType()

Method Detail

isMutable

public final boolean isMutable()

Description copied from interface: Type

Are objects of this type mutable. (With respect to the referencing object ... entities and collections are considered immutable because they manage their own internal state.)

Returns:

boolean

---

hasNiceEquals

public boolean hasNiceEquals()

Description copied from interface: Type

Does this type implement a well-behaved equals() method. (ie. one that is consistent with Type.equals().) Strictly, if this method returns true then x.equals(y) implies Type.equals(x, y) and also Type.equals(x, y) implies that probably x.equals(y)

Object.equals(java.lang.Object), Type.equals(java.lang.Object, java.lang.Object)
