Hi Marcel,
here a piece of code that shows more less what I'm trying to do. I have the
NodeState of the verison I want to modify (versionNodeState) and I create
from it the updated version (updatedNodeState), but then I don't understand
how can I use it to update the actual value in the FrozenNode:
public void changeFirstVersionProperty(NodeStore nodeStore, Node
myFolder) throws IOException, InvalidFileStoreVersionException,
RepositoryException {
NodeState versionNodeState = getNodeState(nodeStore, myFolder);
NodeState updatedNodeState =
versionNodeState.builder().setProperty("custom:trashed",
true).getNodeState();
}
private NodeState getNodeState(NodeStore nodeStore, Node node) throws
RepositoryException {
NodeState rootState = nodeStore.getRoot();
NodeState versionStorageState =
rootState.getChildNode(JcrConstants.JCR_SYSTEM).getChildNode(JcrConstants.JCR_VERSIONSTORAGE);
NodeState versionHistoryState =
getVersionHistoryState(versionStorageState, node.getIdentifier());
return
versionHistoryState.getChildNode("1.0").getChildNode(JcrConstants.JCR_FROZENNODE);
}
private NodeState getVersionHistoryState(NodeState nodeState, String
remainingIdentifier) {
String clusterFolderName = remainingIdentifier.substring(0, 2);
NodeState childNode = nodeState.getChildNode(clusterFolderName);
if (childNode.exists()) {
return getVersionHistoryState(childNode,
remainingIdentifier.substring(2));
} else {
String versionHistoryNodeName = getFirstChild(nodeState);
return nodeState.getChildNode(versionHistoryNodeName);
}
}
private String getFirstChild(NodeState nodeState) {
return nodeState.getChildNodeNames().iterator().next();
}
Marco.
