Class SpecialObjectType

  • All Implemented Interfaces:
    Type
    Direct Known Subclasses:
    LangObjType

    public class SpecialObjectType
    extends ObjectType
    Used for object types that don't correspond to JVM types. These are implemented by some implementation type (a ClassType), but may have extra non-standard properties.

        public Class getReflectClass()
        Description copied from class: ObjectType
        Get the java.lang.Class object for the representation type.

      • getRealType

        public Type getRealType()
        Description copied from class: Type
        If this is a type alias, get the aliased type. This is semi-deprecated.
        Overrides:
        getRealType in class Type
      • getImplementationType

        public Type getImplementationType()
        Description copied from class: Type
        Return Java-level implementation type. The type used to implement types not natively understood by the JVM or the Java language. Usually, the identity function. However, a language might handle union types or template types or type expressions calculated at run time. In that case return the type used at the Java level, and known at compile time.
        Overrides:
        getImplementationType in class Type
      • compare

        public int compare​(Type other)
        Description copied from class: Type
        Return a numeric code showing "subtype" relationship: 1: if other is a pure subtype of this; 0: if has the same values; -1: if this is a pure subtype of other; -2: if they have values in common but neither is a subtype of the other; -3: if the types have no values in common. "Same values" is rather loose; by "A is a subtype of B" we mean that all instance of A can be "widened" to B. More formally, A.compare(B) returns: 1: all B values can be converted to A without a coercion failure (i.e. a ClassCastException or overflow or major loss of information), but not vice versa. 0: all A values can be converted to B without a coercion failure and vice versa; -1: all A values can be converted to B without a coercion failure but not vice versa; -2: there are (potentially) some A values that can be converted to B, and some B values can be converted to A; -3: there are no A values that can be converted to B, and neither are there any B values that can be converted to A.
