Queries the specified temporal object. !(p) This queries the specified temporal object to return an object using the logic encapsulated _in the implementing class. Examples might be a query that checks if the date is the day before February 29th _in a leap year, or calculates the number of days to your next birthday. !(p) There are two equivalent ways of using this method. The first is to invoke this method directly. The second is to use {@link TemporalAccessor#query(TemporalQuery)}: !(pre) // these two lines are equivalent, but the second approach is recommended temporal = thisQuery.queryFrom(temporal); temporal = temporal.query(thisQuery); </pre> It is recommended to use the second approach, {@code query(TemporalQuery)}, as it is a lot clearer to read _in code.
Strategy for querying a temporal object. !(p) Queries are a key tool for extracting information from temporal objects. They exist to externalize the process of querying, permitting different approaches, as per the strategy design pattern. Examples might be a query that checks if the date is the day before February 29th _in a leap year, or calculates the number of days to your next birthday. !(p) The {@link TemporalField} interface provides another mechanism for querying temporal objects. That interface is limited to returning a {@code long}. By contrast, queries can return any type. !(p) There are two equivalent ways of using a {@code TemporalQuery}. The first is to invoke the method on this interface directly. The second is to use {@link TemporalAccessor#query(TemporalQuery)}: !(pre) // these two lines are equivalent, but the second approach is recommended temporal = thisQuery.queryFrom(temporal); temporal = temporal.query(thisQuery); </pre> It is recommended to use the second approach, {@code query(TemporalQuery)}, as it is a lot clearer to read _in code. !(p) The most common implementations are method references, such as {@code LocalDate.from} and {@code ZoneId::from}. Additional common queries are provided as static methods _in {@link TemporalQueries}.
@implSpec This interface places no restrictions on the mutability of implementations, however immutability is strongly recommended.
