Modifier and Type	Method and Description
static EnumResolver	constructFor(Class<Enum<?>> enumCls, AnnotationIntrospector ai) Factory method for constructing resolver that maps from Enum.name() into Enum value
CompactStringObjectMap	constructLookup()
static EnumResolver	constructUnsafe(Class<?> rawEnumCls, AnnotationIntrospector ai) This method is needed because of the dynamic nature of constructing Enum resolvers.
static EnumResolver	constructUnsafeUsingMethod(Class<?> rawEnumCls, Method accessor) Method used when actual String serialization is indicated using @JsonValue on a method.
static EnumResolver	constructUnsafeUsingToString(Class<?> rawEnumCls) Method that needs to be used instead of constructUsingToString(java.lang.Class<java.lang.Enum<?>>) if static type of enum is not known.
static EnumResolver	constructUsingMethod(Class<Enum<?>> enumCls, Method accessor)
static EnumResolver	constructUsingToString(Class<Enum<?>> enumCls) Factory method for constructing resolver that maps from Enum.toString() into Enum value

Constructor Detail

EnumResolver

protected EnumResolver(Class<Enum<?>> enumClass,
                       Enum<?>[] enums,
                       HashMap<String,Enum<?>> map)

Method Detail

constructFor

public static EnumResolver constructFor(Class<Enum<?>> enumCls,
                                        AnnotationIntrospector ai)

Factory method for constructing resolver that maps from Enum.name() into Enum value

constructUsingToString

public static EnumResolver constructUsingToString(Class<Enum<?>> enumCls)

Factory method for constructing resolver that maps from Enum.toString() into Enum value

constructUsingMethod

public static EnumResolver constructUsingMethod(Class<Enum<?>> enumCls,
                                                Method accessor)

constructUnsafe

public static EnumResolver constructUnsafe(Class<?> rawEnumCls,
                                           AnnotationIntrospector ai)

This method is needed because of the dynamic nature of constructing Enum resolvers.

constructUnsafeUsingToString

public static EnumResolver constructUnsafeUsingToString(Class<?> rawEnumCls)

Method that needs to be used instead of constructUsingToString(java.lang.Class<java.lang.Enum<?>>) if static type of enum is not known.

constructUnsafeUsingMethod

public static EnumResolver constructUnsafeUsingMethod(Class<?> rawEnumCls,
                                                      Method accessor)

Method used when actual String serialization is indicated using @JsonValue on a method.
