struct	fieldorder_wrapper
	fieldorder_wrapper is an internal class that is used to wrap instances of FieldOrder accessors, currying in the specific location on the field. This is used as a helper class for fixed-point accessors providing the necessary conversion and scaling when writing to a fixed-point field. More...
