org.elasticsearch.common.inject.internal.MoreTypes
public class MoreTypes
extends java.lang.Object
Static methods for working with types that we aren't publishing in the public Types API.

  • Nested Class Summary

    Nested Classes 
    Modifier and Type Class Description
    static class  MoreTypes.GenericArrayTypeImpl  
    static class  MoreTypes.MemberImpl
    We cannot serialize the built-in Java member classes, which prevents us from using Members in our exception types.
    static class  MoreTypes.ParameterizedTypeImpl  
    static class  MoreTypes.WildcardTypeImpl
    The WildcardType interface supports multiple upper bounds and multiple lower bounds.

  • Method Summary

    Modifier and Type Method Description
    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().
    static boolean equals​(java.lang.reflect.Type a, java.lang.reflect.Type b)
    Returns true if a and b are equal.
    static java.lang.reflect.Type getGenericSupertype​(java.lang.reflect.Type type, java.lang.Class<?> rawType, java.lang.Class<?> toResolve)
    Returns the generic supertype for supertype.
    static java.lang.Class<?> getRawType​(java.lang.reflect.Type type)  
    static int hashCode​(java.lang.reflect.Type type)
    Returns the hashCode of type.
    static <T> TypeLiteral<T> makeKeySafe​(TypeLiteral<T> type)
    Returns an equivalent type that's safe for use in a key.
    static java.lang.String memberKey​(java.lang.reflect.Member member)  
    static java.lang.Class<? extends java.lang.reflect.Member> memberType​(java.lang.reflect.Member member)
    Returns Field.class, Method.class or Constructor.class.
    static java.lang.reflect.Type resolveTypeVariable​(java.lang.reflect.Type type, java.lang.Class<?> rawType, java.lang.reflect.TypeVariable unknown)  
    static java.lang.String toString​(java.lang.reflect.Member member)
    Formats a member as concise string, such as java.util.ArrayList.size, java.util.ArrayList<init>() or java.util.List.remove().

    • EMPTY_TYPE_ARRAY

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

  • Method Details

    • makeKeySafe

      public static <T> TypeLiteral<T> makeKeySafe​(TypeLiteral<T> type)
      Returns an equivalent type that's safe for use in a key. The returned type will be free of primitive types. Type literals of primitives will return the corresponding wrapper types.
      Throws:
      ConfigurationException - if type contains a type variable

    • 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().

    • 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.

    • hashCode

      public static int hashCode​(java.lang.reflect.Type type)
      Returns the hashCode of type.

    • toString

      public static java.lang.String toString​(java.lang.reflect.Type type)

    • memberType

      public static java.lang.Class<? extends java.lang.reflect.Member> memberType​(java.lang.reflect.Member member)
      Returns Field.class, Method.class or Constructor.class.

    • toString

      public static java.lang.String toString​(java.lang.reflect.Member member)
      Formats a member as concise string, such as java.util.ArrayList.size, java.util.ArrayList<init>() or java.util.List.remove().

    • memberKey

      public static java.lang.String memberKey​(java.lang.reflect.Member member)

    • 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 supertype. 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)
