Replaces the entry for a key only if it is currently mapped to a given value.

This is equivalent to:
    >>> if map.contains_key(key) and map.get(key).equals(old_value):
    >>>     map.put(key, new_value)
    >>>     return true
    >>> else:
    >>>     return false
except that the action is performed atomically.

**Warning: This method uses __hash__ and __eq__ methods of binary form of the key, not the actual implementations
of __hash__ and __eq__ defined in key's class.**

:param key: (object), the specified key.
:param old_value: (object), replace the key value if it is the old value.
:param new_value: (object), the new value to replace the old value.
:return: (bool), ``true`` if the value was replaced.
