Slots

pointer:

external pointer to the EnumValueDescriptor instance

name:

simple name of the enum

full_name:

fully qualified name

Methods

show

signature(object = "EnumValueDescriptor"): small information

as.character

signature(x = "EnumValueDescriptor"): returns the debug string of the enum descriptor. This is retrieved by a call to the DebugString method of the EnumDescriptor object.
