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.- Specified by:

isCompatibleWithValue
Description copied from class:Type
If this is the target type, is a given source type compatible?- Overrides:
isCompatibleWithValue
in classType
- Returns:
- -1 if not compatible; 0 if need to check at run-time; 1 if compatible; 2 if compatible and no conversion or cast needed. We also return 0 for some "narrowing" conversions even if we know they will always succeed, so as to make such conversions less preferred when doing method overloading.

compare
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.- Overrides:
