Pass a value from this enum to UsePropertyAccessMode(PropertyAccessMode), UsePropertyAccessMode(PropertyAccessMode), or UsePropertyAccessMode(PropertyAccessMode) to change whether the property or backing field will be used when reading and writing to a property or field.

If no access mode is set, then the backing field for a property will be used if possible when constructing new instances of the entity. The property getter or setter will be used, if possible, for all other accesses of the property. Note that when it is not possible to use the field because it could not be found by convention and was not specified using HasField(String), then the property will be used instead. Likewise, when it is not possible to use the property getter or setter, for example when the property is read-only, then the field will be used instead.
