java.lang.Object

org.jboss.jandex.Type

org.jboss.jandex.WildcardType

public class WildcardType
extends Type

Represents a generic wildcard. A generic wildcard can have either an upper (extends) or a lower (super) bound. A wildcard declared without a bound ("?") has a default extends bound of "java.lang.Object".

Method Detail

create

public static WildcardType create(Type bound,
                                  boolean isExtends)

Create a new mock instance of WildcardType.

Parameters:

bound - the bound (lower or upper)

isExtends - true if lower, false if upper (super)

Returns:

thew new mock instance

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

extendsBound

public Type extendsBound()

Returns the upper bound of this wildcard (e.g. SomeType for ? extends SomeType).

Returns java.lang.Object if this wildcard declares a lower bound (? super SomeType).

Returns:

the upper bound, or Object if this wildcard has a lower bound

superBound

public Type superBound()

Returns the lower bound of this wildcard (e.g. SomeType for ? super SomeType).

Returns null if this wildcard declares an upper bound (? extends SomeType).

Returns:

the lower bound, or null if this wildcard has an uper bound

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

asWildcardType

public WildcardType asWildcardType()

Description copied from class: Type

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

Overrides:

asWildcardType in class Type

Returns:

a WildcardType

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)
