Method Detail

getDefaultEnumConstant

protected static String getDefaultEnumConstant()

The enum constant postfix used as default value in protobuf, ie for enum "Cake" the default constant should be CAKE_UNSPECIFIED = 0; This is the recommended style according to Googles style guide https://developers.google.com/protocol-buffers/docs/style#enums . If you use some other pattern in your protobuf files you can simply subclass this class and override this method.

isMapEnumConstantToNull

public boolean isMapEnumConstantToNull(TypeElement enumType,
                                       String sourceEnumValue)

getDefaultNullEnumConstant

public String getDefaultNullEnumConstant(TypeElement enumType)

Specified by:

getDefaultNullEnumConstant in interface org.mapstruct.ap.spi.EnumMappingStrategy

Overrides:

getDefaultNullEnumConstant in class org.mapstruct.ap.spi.DefaultEnumMappingStrategy

getEnumConstant

public String getEnumConstant(TypeElement enumType,
                              String sourceEnumValue)

Specified by:

getEnumConstant in interface org.mapstruct.ap.spi.EnumMappingStrategy

Overrides:
