Method Summary |
int |
compare(Type other)
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. |

getImplementationType
public Type getImplementationType()
- Description copied from class:
Type
- The type used to implement types not natively understood by the JVM.
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 JVM level,
and known at compile time.
- Overrides:
getImplementationType in class ObjectType
make
public static ArrayType make(Type elements)
- Find or create an ArrayType for the specified element type.
getComponentType
public Type getComponentType()
getInternalName
public java.lang.String getInternalName()
- Description copied from class:
ObjectType
- Returns class name if a class type, signature if an array type.
In both cases, uses '/' rather than '.' after packages prefixes.
Seems rather arbitrary - but that is how classes are represented
in the constant pool (CONSTANT_Class constants).
Also, Class.forName is the same, except using '.'.
- Overrides:
getInternalName in class ObjectType
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 member" 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
not 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:
