4.10.1 Subtyping among Primitive Types

The following rules define the direct supertype relation among the primitive types:

• double >1 float
• float >1 long
• long >1 int
• int >1 char
• int >1 short
• short >1 byte

参数:

sub -

directSuperAmongClassAndInterfaceType

public static AClass[] directSuperAmongClassAndInterfaceType(AClass subType)

4.10.2 Subtyping among Class and Interface Types Given a generic type declaration C, the direct supertypes of the parameterized type C are all of the following:

• The direct superclasses of C.
• The direct superinterfaces of C.
• The type Object, if C is an interface type with no direct superinterfaces.
• The raw type C.

The direct supertypes of the parameterized type C, where Ti (1 ≤ i ≤ n) is a type, are all of the following:

• D, where D is a direct supertype of C and θ is the substitution [F1:=T1,...,Fn:=Tn].
• C, where Si contains Ti (1 ≤ i ≤ n) (§4.5.1).

The direct supertypes of the parameterized type C, where at least one of the Ri (1 ≤ i ≤ n) is a wildcard type argument, are the direct supertypes of C which is the result of applying capture conversion (§5.1.10) to C. The direct supertypes of an intersection type T1 & ... & Tn are Ti (1 ≤ i ≤ n). The direct supertypes of a type variable are the types listed in its bound. A type variable is a direct supertype of its lower bound. The direct supertypes of the null type are all reference types other than the null type itself.

directSuperAmongArrayType

public static AClass[] directSuperAmongArrayType(AClass subType)

4.10.3 Subtyping among Array Types

The following rules define the direct supertype relation among array types:

• If S and T are both reference types, then S[] >1 T[] iff S >1 T.
• Object >1 Object[]
• Cloneable >1 Object[]
• java.io.Serializable >1 Object[]
• If P is a primitive type, then:
• Object >1 Object[]
• Cloneable >1 Object[]
• java.io.Serializable >1 Object[]

参数:

subType -
