Examples of InternalNode

com.bazaarvoice.jless.ast.node.InternalNode
Super class for all internal nodes of the tree. A variety of methods allow for manipulating the children of an InternalNode, while still ensuring that only one parent owns a given child node at any one time. A mutable iterator is available, allowing for typical {@link ListIterator} operations, as well as modifications at arbitrary indices from the iterator.Additionally, the child set may be modified while iteration is occurring without going through the iterator directly.

org.jboss.cache.InternalNode
An internal node interface, that represents nodes that directly form the tree structure in the cache. This is as opposed to {@link Node} and its {@link NodeSPI} sub-interface, which are typically implemented by delegates which then delegate callsto internal nodes, potentially after passing the call up an interceptor chain.
All calls on an InternalNode are executed directly on the data structure. Usually, XXXDirect() calls on {@link NodeSPI}delegate to calls on an InternalNode, for example, {@link NodeSPI#putDirect(Object,Object)} delegating to {@link #put(Object,Object)}.
