new Element(type, resolvedType, isMapKey, syntax, name)
Constructs a new Element implementation that checks and converts values for a particular field type, as appropriate.
An Element represents a single value: either the value of a singular field, or a value contained in one entry of a repeated field or map field. This class does not implement these higher-level concepts; it only encapsulates the low-level typechecking and conversion.
Parameters:

resolvedType |
ProtoBuf.Reflect.T | null | Resolved type, if relevant (e.g. submessage field). |
