Class TypeVariable

java.lang.Object

org.jboss.jandex.Type

org.jboss.jandex.TypeVariable

public final class TypeVariable
extends Type

Represents a resolved type parameter or type argument. The name() of this type variable corresponds to the raw type name. For type variables, the raw type name is the first upper bound. The identifier() is the name of the type variable as present in the source code.

For example:

 T extends Number
 

In this case, the identifier is T, while the name is java.lang.Number.

Method Detail

name

public DotName name()

Description copied from class: Type

Returns the raw name of this type. Primitives and void are returned as the Java keyword (void, boolean, byte, short, int, long, float, double, char). Arrays are returned using the Java reflection array syntax (e.g. [[[Ljava.lang.String;) Classes are returned as a normal DotName.

Generic values are returned as the underlying raw value. For example, a wildcard such as ? extends Number has a raw type of Number.

Overrides:

name in class Type

Returns:

the name of this type

identifier

public String identifier()

The identifier of this type variable as it appears in Java source code.

The following class has a type parameter, with an identifier of "T":

 class Foo<T extends Number> {
 }
 

Returns:

the identifier of this type variable

bounds

public List<Type> bounds()

kind

public Type.Kind kind()

Description copied from class: Type

Returns the kind of Type this is.

Specified by:

kind in class Type

Returns:

the kind

asTypeVariable

public TypeVariable asTypeVariable()

Description copied from class: Type

Casts this type to a TypeVariable and returns it if the kind is Type.Kind.TYPE_VARIABLE. Throws an exception otherwise.

Overrides:

asTypeVariable in class Type

Returns:

a TypeVariable

equals

public boolean equals(Object o)

Description copied from class: Type

Compares this Type with another type. A type is equal to another type if it is of the same kind, and all of their fields are equal. This includes annotations, which must be equal as well.

Overrides:

equals in class Type

Parameters:

o - the type to compare to

Returns:

true if equal

Object.equals(Object)

hashCode

public int hashCode()

Description copied from class: Type

Computes a hash code representing this type.

Overrides:

hashCode in class Type

Returns:

the hash code

internEquals

public boolean internEquals(Object o)

Overrides:

internEquals in class Type

internHashCode

public int internHashCode()

Overrides:

internHashCode in class Type

arrayEquals

public static boolean arrayEquals(org.jboss.jandex.Interned[] a,
                                  org.jboss.jandex.Interned[] b)

arrayHashCode

public static int arrayHashCode(org.jboss.jandex.Interned[] array)
