> Issue Type: Improvement
> Components: core

> Priority: Minor
> Fix For: 0.7

>
> 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).
