getNeighborsSize
public int getNeighborsSize()
Get size of the list returned fromgetNeighborsSubList(FieldAbsoluteDate, List)
.- Returns:
- size of the list returned from
getNeighborsSubList(FieldAbsoluteDate, List)

getNeighborsSubList
public <T extends FieldTimeStamped<K>,K extends CalculusFieldElement<K>> List<T> getNeighborsSubList(FieldAbsoluteDate<K> central, List<T> data)
Get the entries surrounding a central date.If the central date is well within covered range, the returned array will be balanced with half the points before central date and half the points after it (depending on n parity, of course). If the central date is near the boundary, then the returned array will be unbalanced and will contain only the n earliest (or latest) entries. A typical example of the later case is leap seconds cache, since the number of leap seconds cannot be arbitrarily increased.
