- abstract def at(time: Long)(implicit tx: T): Option[Entry[T, Obj[T]]]
Queries the element valid for the given point in time.
Queries the element valid for the given point in time. Unlike,
intersect
, if there are multiple elements sharing the same point in time, this returns the most recently added element.We propose that this should be the unambiguous way to evaluate the
BiPin
for a given moment in time.- time
the query time point
- returns
an element for the given time point, if it exists, otherwise
None

- BiPin
- abstract def ceil(time: Long)(implicit tx: T): Option[Entry[T, Obj[T]]]
Finds the entry at the given time, or the closest entry after the given time.
Finds the entry at the given time, or the closest entry after the given time.
- time
the query time
- returns
the entry nearest in time to the query time, but not earlier than the query time, or
None
if there is no entry at such time

- abstract def eventAfter(time: Long)(implicit tx: T): Option[Long]
Finds the entry with the smallest time which is greater than the query time.
Finds the entry with the smallest time which is greater than the query time.
- time
the query time
- returns
the time corresponding to the next entry, or
None
if there is no entry later than the given time

- abstract def eventBefore(time: Long)(implicit tx: T): Option[Long]
Finds the entry with the greatest time which is less than the query time.
Finds the entry with the greatest time which is less than the query time.
- time
the query time
- returns
the time corresponding to the next entry, or

Finds the entry at the given time, or the closest entry before the given time.
Finds the entry at the given time, or the closest entry before the given time.
- time
the query time
- returns
the entry nearest in time to the query time, but not later than the query time, or

- abstract def intersect(time: Long)(implicit tx: T): Leaf[T, Obj[T]]
Queries all elements which are found at a given point in time.
Queries all elements which are found at a given point in time. There may be multiple time expressions which are not equal but evaluate to the same moment in time. It is thus possible that for a given point, multiple elements are found.
- time
the query point
- returns
the sequence of elements found along with their time expressions
