-----------------------------------------
Summary: Let DataNode.getChildren() return an unmodifiable view of
its children set
Key: ZOOKEEPER-2194
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2194
Project: ZooKeeper
Issue Type: Improvement
Reporter: Hitoshi Mitake
Priority: Trivial
Current DataNode.getChildren() directly returns a pointer of its private
member, children. However, the member should be modified through addChild()
and removeChild(). Callers of getChildren() shouldn't modify it directly.
For preventing the direct modification by the callers, this patch lets
getChildren() return an unmodifiable view of its children set. If the callers
try to modify directly, runtime exception will be risen.
