Method Summary

Modifier and Type	Method and Description
static EnumResolver	constructFor(java.lang.Class<java.lang.Enum<?>> enumCls, AnnotationIntrospector ai) Factory method for constructing resolver that maps from Enum.name() into Enum value
CompactStringObjectMap	constructLookup()
static EnumResolver	constructUnsafe(java.lang.Class<?> rawEnumCls, AnnotationIntrospector ai) This method is needed because of the dynamic nature of constructing Enum resolvers.
static EnumResolver	constructUnsafeUsingMethod(java.lang.Class<?> rawEnumCls, AnnotatedMember accessor, AnnotationIntrospector ai) Method used when actual String serialization is indicated using @JsonValue on a method.
static EnumResolver	constructUnsafeUsingToString(java.lang.Class<?> rawEnumCls, AnnotationIntrospector ai) 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(java.lang.Class<java.lang.Enum<?>> enumCls, AnnotatedMember accessor, AnnotationIntrospector ai)
static EnumResolver	constructUsingToString(java.lang.Class<java.lang.Enum<?>> enumCls) Deprecated. Since 2.8, use constructUsingToString(Class, AnnotationIntrospector) instead

Method Detail

constructFor

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

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

constructUsingToString

@Deprecated
public static EnumResolver constructUsingToString(java.lang.Class<java.lang.Enum<?>> enumCls)

Deprecated. Since 2.8, use constructUsingToString(Class, AnnotationIntrospector) instead

constructUsingToString

public static EnumResolver constructUsingToString(java.lang.Class<java.lang.Enum<?>> enumCls,
                                                  AnnotationIntrospector ai)

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

Since:

2.8

constructUsingMethod

public static EnumResolver constructUsingMethod(java.lang.Class<java.lang.Enum<?>> enumCls,
                                                AnnotatedMember accessor,
                                                AnnotationIntrospector ai)

Since:

2.9

constructUnsafe

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

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

constructUnsafeUsingToString

public static EnumResolver constructUnsafeUsingToString(java.lang.Class<?> rawEnumCls,
                                                        AnnotationIntrospector ai)

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

Since:

2.8

constructUnsafeUsingMethod

public static EnumResolver constructUnsafeUsingMethod(java.lang.Class<?> rawEnumCls,
                                                      AnnotatedMember accessor,
                                                      AnnotationIntrospector ai)

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

Since:
