Returns a view of the portion of this map whose keys are
greater than or equal to fromKey. The returned map is
backed by this map, so changes in the returned map are
reflected in this map, and vice-versa. The returned map
supports all optional map operations that this map supports.
The returned map will throw an IllegalArgumentException
on an attempt to insert a key outside its range.
fromKey | low endpoint (inclusive) of the keys in the returned map |
fromKey
ClassCastException | if fromKey is not compatible
with this map's comparator (or, if the map has no comparator,
if fromKey does not implement Comparable).
Implementations may, but are not required to, throw this
exception if fromKey cannot be compared to keys
currently in the map. | |
NullPointerException | if fromKey is null and
this map does not permit null keys | |
IllegalArgumentException | if this map itself has a
restricted range, and fromKey lies outside the
bounds of the range |
