[infinispan-issues] [JBoss JIRA] Issue Comment Edited: (ISPN-1213) TreeCache expires parents that have children

[ https://issues.jboss.org/browse/ISPN-1213?page=com.atlassian.jira.plugin.... ] Todd Ciezadlo edited comment on ISPN-1213 at 7/5/11 2:07 PM: ------------------------------------------------------------- A work-around is to climb the parents and call Node.getNode(FQN) on each one instead of Node.get(String,String) or Node.get(Fqn,String). Attached TreeCacheUtil.java that does this (substituted String for the K generic). was (Author: ciezadlo): A work-around is to climb the parents and call Node.getNode(FQN) on each one instead of Node.get(String,String) or Node.get(Fqn,String). Example replacement method (generic K replaced with String): /** * Gets the value for the given FQN and key. * <p> * Traverses the parents of the given FQN to reset their idle times. * * @param fqn the FQN * @param key the key * @return value of the FQN and key; or null if non-existent */ private static Object getAndTouchParents(TreeCache cache, String fqn, String key) { Object value = null; Node<Object, Object> node = cache.getNode(fqn); if (node != null) { value = node.get(key); Fqn parentFqn; do { Node<Object, Object> parent = node.getParent(); parentFqn = parent.getFqn(); if (parentFqn != null) { cache.getNode(parentFqn); // touch the parent to reset the idle time } } while (parentFqn != null && !parentFqn.isRoot()); } return value; } -- This message is automatically generated by JIRA.
