Field Detail

EMPTY_TYPE_ARRAY

public static final java.lang.reflect.Type[] EMPTY_TYPE_ARRAY

PRIMITIVE_TO_WRAPPER

private static final com.google.common.collect.ImmutableMap<TypeLiteral<?>,TypeLiteral<?>> PRIMITIVE_TO_WRAPPER

private MoreTypes()
```

Method Detail

canonicalizeKey
```
public static <T> Key<T> canonicalizeKey(Key<T> key)
```
Returns a key that doesn't hold any references to parent classes. This is necessary for anonymous keys, so ensure we don't hold a ref to the containing module (or class) forever.

canonicalizeForKey
```
public static <T> TypeLiteral<T> canonicalizeForKey(TypeLiteral<T> typeLiteral)
```
Returns an type that's appropriate for use in a key.
If the raw type of typeLiteral is a javax.inject.Provider, this returns a com.google.inject.Provider with the same type parameters.
If the type is a primitive, the corresponding wrapper type will be returned.

Throws:

ConfigurationException - if type contains a type variable

isFullySpecified

private static boolean isFullySpecified(java.lang.reflect.Type type)

Returns true if type is free from type variables.

canonicalize
```
public static java.lang.reflect.Type canonicalize(java.lang.reflect.Type type)
```
Returns a type that is functionally equal but not necessarily equal according to Object.equals(). The returned type is Serializable.

getRawType

public static java.lang.Class<?> getRawType(java.lang.reflect.Type type)

equals

public static boolean equals(java.lang.reflect.Type a,
                             java.lang.reflect.Type b)

Returns true if a and b are equal.

hashCodeOrZero

private static int hashCodeOrZero(java.lang.Object o)

typeToString

public static java.lang.String typeToString(java.lang.reflect.Type type)

getGenericSupertype

public static java.lang.reflect.Type getGenericSupertype(java.lang.reflect.Type type,
                                                         java.lang.Class<?> rawType,
                                                         java.lang.Class<?> toResolve)

Returns the generic supertype for type. For example, given a class IntegerSet, the result for when supertype is Set.class is Set<Integer> and the result when the supertype is Collection.class is Collection<Integer>.

resolveTypeVariable

public static java.lang.reflect.Type resolveTypeVariable(java.lang.reflect.Type type,
                                                         java.lang.Class<?> rawType,
                                                         java.lang.reflect.TypeVariable unknown)

indexOf

private static int indexOf(java.lang.Object[] array,
                           java.lang.Object toFind)

declaringClassOf

private static java.lang.Class<?> declaringClassOf(java.lang.reflect.TypeVariable typeVariable)

Returns the declaring class of typeVariable, or null if it was not declared by a class.

checkNotPrimitive

private static void checkNotPrimitive(java.lang.reflect.Type type,
                                      java.lang.String use)
