------------------------------------
Summary: Implement KernelNodeState.hasChildNode()
Key: OAK-726
URL: https://issues.apache.org/jira/browse/OAK-726
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Marcel Reutegger
Assignee: Marcel Reutegger
Priority: Minor
During tests I frequently see KernelNodeState.getChildPath() and
KernelNodeState.getChildNode() as hot spots. Some of those calls can be avoided
when KernelNodeState implements hasChildNode(). Currently it will just fall
back to the generic implementation in AbstractNodeState, which attempts to load
the child node. In most cases this is unnecessary when the node state is a
KernelNodeState because this implementation keeps the child node names in a set
(up to MAX_CHILD_NODE_NAMES).
