| Modifier and Type | Method and Description |
|---|---|
Object |
getConfigurationNode(Path path,
Class configurableClass)
Loads a configuration node under the specified path.
|
Map<String,Object> |
getConfigurationRoot()
Return the root of the configuration tree.
|
Path |
getPathByUUID(String uuid) |
void |
lock()
Aquire a global pessimistic lock (cluster-aware implementations should ensure that only a single node can aquire the lock at a time)
Subsequent calls from the same transaction should not block.
|
boolean |
nodeExists(Path path)
Tests if a node under the specified path exists.
|
void |
persistNode(Path path,
Map<String,Object> configNode,
Class configurableClass)
Persists the configuration node to the specified path.
|
void |
refreshNode(Path path)
Invalidates any present cached state for the node
It is imperative that some other nodes might also be refreshed during the operation.
|
void |
removeNode(Path path)
Removes a configuration node under the specified path with all its children permanently
|
void |
runBatch(BatchRunner.Batch batch)
Provides support for batching configuration changes.
|
Iterator |
search(String liteXPathExpression)
Performs a search on the configuration tree and returns an iterator to configuration nodes that satisfy the search criteria.
