Remarks

Gets the value of this field from the specified temporal object.

This queries the temporal object for the value of this field.

There are two equivalent ways of using this method. The first is to invoke this method directly. The second is to use TemporalAccessor#getLong(TemporalField) (or TemporalAccessor#get(TemporalField)):

// these two lines are equivalent, but the second approach is recommended
              temporal = thisField.getFrom(temporal);
              temporal = temporal.getLong(thisField);

It is recommended to use the second approach, getLong(TemporalField), as it is a lot clearer to read in code.

Implementations should perform any queries or calculations using the fields available in ChronoField. If the field is not supported an UnsupportedTemporalTypeException must be thrown.
