Class ContextAwareTreeNode

java.lang.Object
org.terracotta.context.ContextAwareTreeNode
All Implemented Interfaces:
TreeNode, WeakIdentityHashMap.Cleanable
class ContextAwareTreeNode extends Object implements TreeNode
Node used to wrap real tree node to keep the context object. Only used by ContextManager.nodeFor(Object) to allow the fluent interface to forward the context to TreeNode methods.

Currently, the only method using it is clean() that will make sure the context is removed from the PassThroughStatistic<T extends Serializable>
