Method Detail

getByPoint

public V getByPoint(Comparable<T> point)

Description copied from interface: SortedRangeMap

Returns the value to which this map maps a key with a range that the specified point falls within. Returns null if the map contains no mapping for any key with such range. A return value of null does not necessarily indicate that the map contains no mapping for a key with such range; it's also possible that the map explicitly maps the key with such range to null. The containsKeyPoint operation may be used to distinguish these two cases.

Specified by:

getByPoint in interface SortedRangeMap<T,K,V>

Parameters:

point - the point that falls within the range of a key whose associated value is to be returned.

Returns:

the value to which this map maps a key with a range that the specified point falls within, or null if the map contains no mapping for any key with such range.

SortedRangeMap.containsKeyPoint(Comparable)

containsKeyPoint

public boolean containsKeyPoint(Comparable<T> point)

Description copied from interface: SortedRangeMap

Returns true if this map contains a mapping of a key with a range that the specified point falls within.

Specified by:

containsKeyPoint in interface SortedRangeMap<T,K,V>

Parameters:

point - point to be tested.

Returns:

true if this map contains a mapping of a key with a range that the specified point falls within.
