- Method Detail
  - get
```
java.util.Optional<ChildData> get(java.lang.String path)
```
    Return an entry from storage
    
    Parameters:
    
    path - path to get
    
    Returns:
    
    entry or empty()
  - size
```
int size()
```
    Return the current number of entries in storage
    
    Returns:
    
    number of entries
  - stream
```
java.util.stream.Stream<ChildData> stream()
```
    Return a stream over the storage entries. Note: for a standard storage instance, the stream behaves like a stream returned by ConcurrentHashMap.entrySet()
    
    Returns:
    
    stream over entries
  - parentPathFilter
```
static java.util.function.Predicate<ChildData> parentPathFilter(java.lang.String parentPath)
```
    Filter for a ChildData stream. Only ChildDatas with the given parent path pass the filter. This is useful to stream one level below a given path in the cache. e.g. to stream only the first level below the root of the cache. CuratorCache cache = ... cache.stream().filter(parentPathFilter(root))... // etc
    Parameters:
    
    parentPath - the parent path to filter on
    
    Returns:
    
    filtered stream
