public class ProtoEnumNameUtils
extends java.lang.Object

Because in Go enums are in a shared namespace, one of protobuf common practices is to prefix the enums with enum name prefix to create unique names. The final result is verbose and when we use a string representation of some enum in different parts of the system (history json or search attribute types), we use a short version without prefix in camel case. So, protobuf enum EventType.EVENT_TYPE_WORKFLOW_EXECUTION_STARTED gets converted to "WorkflowExecutionStarted"

AIP 126
- The other values should not be prefixed by the name of the enum itself. This generally requires users to write MyState.MYSTATE_ACTIVE in their code, which is unnecessarily verbose. - To avoid sharing values, APIs may prefix enum values with the name of the enum. In this case, they must do so consistently within the enum.
