Class AdaptableDate

java.lang.Object

org.ametys.core.util.date.AdaptableDate

public final class AdaptableDate
extends Object

This represents an advanced LocalDateTime, allowing to be a static one, or a relative one to the moment the resolveDateTime() method is called.
A single instance of AdaptableDate can be resolved mutliple times, without being a problem at all, it just can lead to different results.

You can get an AdaptableDate with:

• fromDateTime(java.time.LocalDateTime) to have a static one, always resolved as the same given LocalDateTime
• fromDate(java.time.LocalDate) to have a static one, always resolved as the same given LocalDate (at the start of the day)
• now() to have one resolved as the current LocalDateTime when resolveDateTime() is called
• future(long, java.time.temporal.TemporalUnit) to have one resolved with the given amount of given TemporalUnit added to the current LocalDateTime when resolveDateTime() is called
• past(long, java.time.temporal.TemporalUnit) to have one resolved with the given amount of given TemporalUnit subtracted to the current LocalDateTime when resolveDateTime() is called
