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.int

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. -
coerceFromObject
Description copied from class:Type
Convert an object to a value of this Type. The result is actually of the implementation type, boxed as appropriate, so it is suitable for standard reflective operations, like the arguments to Field#set or Method#invoke. Throw a ClassCastException when this is not possible.- 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.
