示例1: isSupported
import java.time.temporal.ChronoField; //導入方法依賴的package包/類
@Override
public boolean isSupported(TemporalField field) {
if (field instanceof ChronoField) {
ChronoField f = (ChronoField) field;
return f.isDateBased() || f.isTimeBased();
}
return field != null && field.isSupportedBy(this);
}
示例2: range
import java.time.temporal.ChronoField; //導入方法依賴的package包/類
/**
* Gets the range of valid values for the specified field.
* <p>
* The range object expresses the minimum and maximum valid values for a field.
* This date is used to enhance the accuracy of the returned range.
* If it is not possible to return the range, because the field is not supported
* or for some other reason, an exception is thrown.
* <p>
* If the field is a {@link ChronoField} then the query is implemented here.
* The {@link #isSupported(TemporalField) supported fields} will return
* appropriate range instances.
* All other {@code ChronoField} instances will throw an {@code UnsupportedTemporalTypeException}.
* <p>
* If the field is not a {@code ChronoField}, then the result of this method
* is obtained by invoking {@code TemporalField.rangeRefinedBy(TemporalAccessor)}
* passing {@code this} as the argument.
* Whether the range can be obtained is determined by the field.
*
* @param field the field to query the range for, not null
* @return the range of valid values for the field, not null
* @throws DateTimeException if the range for the field cannot be obtained
* @throws UnsupportedTemporalTypeException if the field is not supported

* <li>{@code YEAR}
* <li>{@code ERA}

* All other {@code ChronoField} instances will return false.
* <p>
* If the field is not a {@code ChronoField}, then the result of this method
* is obtained by invoking {@code TemporalField.isSupportedBy(TemporalAccessor)}

* Whether the field is supported is determined by the field.
