public double getNoEntryValue()
TObjectDoubleMap.get(java.lang.Object) or TObjectDoubleMap.put(K, double) if no

put(k, v) on this map once
for each mapping from key k to value v in the
specified map. The behavior of this operation is undefined if the
specified map is modified while the operation is in progress.putAll in interface TObjectDoubleMap<K>map - mappings to be stored in this mappublic void putAll(TObjectDoubleMap<? extends K> map)

clear in interface TObjectDoubleMap<K>clear in class THashpublic java.util.Set<K> keySet()
Set view of the keys contained in this map.
The set is backed by the map, so changes to the map are
reflected in the set, and vice-versa. If the map is modified
while an iteration over the set is in progress (except through
the iterator's own remove operation), the results of
the iteration are undefined. The set supports element removal,
which removes the corresponding mapping from the map, via the
Iterator.remove, Set.remove,
removeAll, retainAll, and clear
operations. It does not support the add or addAll
operations.keySet in interface TObjectDoubleMap<K>public java.lang.Object[] keys()
