Constructor Detail

SortedListTrimmer

public SortedListTrimmer(int neighborsSize)

Create a new trimmer with the given neighbors size.

Parameters:

neighborsSize - size of the list returned from getNeighborsSubList(AbsoluteDate, List)

Method Detail

getNeighborsSize

public int getNeighborsSize()

Get size of the list returned from getNeighborsSubList(AbsoluteDate, List).

Returns:

size of the list returned from getNeighborsSubList(AbsoluteDate, List)

getNeighborsSubList

public <T extends TimeStamped> List<T> getNeighborsSubList(AbsoluteDate 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.

Type Parameters:

T - the type of data

Parameters:

central - central date

data - complete list of entries (must be chronologically sorted)

Returns:

entries surrounding the specified date (sublist of data)
