Enum TypeToken.Wildcards

java.lang.Object

java.lang.Enum<TypeToken.Wildcards>

uk.co.strangeskies.reflection.token.TypeToken.Wildcards

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<TypeToken.Wildcards>

Enclosing class:

TypeToken<T>

public static enum TypeToken.Wildcards
extends java.lang.Enum<TypeToken.Wildcards>

Treatment of wildcards for TypeTokens created over parameterized types.

Enum Constant Summary

Enum Constants

Enum Constant and Description
CAPTURE Wildcards should be substituted with fresh TypeVariableCapture instances, as per TypeVariableCapture.captureWildcardArguments(ParameterizedType) .
INFER Wildcards should be substituted with inference variables, with appropriate bounds incorporated based on both type variable bounds and wildcard bounds.
RETAIN Wildcards will be left alone, though capture may be necessary for incorporation into backing TypeResolver, as wildcards alone do not always fully specify valid bounds.

Method Summary

Modifier and Type	Method and Description
java.lang.annotation.Annotation	getAnnotation()
static TypeToken.Wildcards	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static TypeToken.Wildcards[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

RETAIN

public static final TypeToken.Wildcards RETAIN

Wildcards will be left alone, though capture may be necessary for incorporation into backing TypeResolver, as wildcards alone do not always fully specify valid bounds.

INFER

public static final TypeToken.Wildcards INFER

Wildcards should be substituted with inference variables, with appropriate bounds incorporated based on both type variable bounds and wildcard bounds.

CAPTURE

public static final TypeToken.Wildcards CAPTURE

Wildcards should be substituted with fresh TypeVariableCapture instances, as per TypeVariableCapture.captureWildcardArguments(ParameterizedType) .

Method Detail

values

public static TypeToken.Wildcards[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TypeToken.Wildcards c : TypeToken.Wildcards.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TypeToken.Wildcards valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getAnnotation

public java.lang.annotation.Annotation getAnnotation()

Returns:

An instance of the annotation which describes this behavior for capture of type literals.
