Examples of java.util.Map.containsValue()

java.util.Map.containsValue()
Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)). This operation will probably require time linear in the map size for most implementations of the Map interface. @param value value whose presence in this map is to be tested @return true if this map maps one or more keys to thespecified value @throws ClassCastException if the value is of an inappropriate type forthis map (optional) @throws NullPointerException if the specified value is null and thismap does not permit null values (optional)
