限定符和类型	方法和说明
static <ET extends Enum<ET>> EnumResolver<ET>	constructFor(Class<ET> enumCls, AnnotationIntrospector ai) Factory method for constructing resolver that maps from Enum.name() into Enum value
static EnumResolver<?>	constructUnsafe(Class<?> rawEnumCls, AnnotationIntrospector ai) This method is needed because of the dynamic nature of constructing Enum resolvers.
static EnumResolver<?>	constructUnsafeUsingToString(Class<?> rawEnumCls) Method that needs to be used instead of constructUsingToString(java.lang.Class<ET>) if static type of enum is not known.
static <ET extends Enum<ET>> EnumResolver<ET>	constructUsingToString(Class<ET> enumCls) Factory method for constructing resolver that maps from Enum.toString() into Enum value

方法详细资料

constructFor

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

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

constructUsingToString

public static <ET extends Enum<ET>> EnumResolver<ET> constructUsingToString(Class<ET> enumCls)

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

从以下版本开始:

1.6

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<ET>) if static type of enum is not known.

从以下版本开始:

1.6

findEnum

public T findEnum(String key)

getEnum

public T getEnum(int index)

getEnumClass

public Class<T> getEnumClass()

lastValidIndex

public int lastValidIndex()
