Method Detail

insert

public void insert(String path,
                   T value)

insertOrUpdate

public void insertOrUpdate(String path,
                           T value,
                           BiFunction<T,T,T> updater)

Insert a value for the given path. If the path already exists, replace the value with:

 value = updater.apply(oldValue, newValue);
 

allowing the value to be updated if desired.

retrieve

public T retrieve(String path)

retrieve

public T retrieve(String path,
                  Map<String,String> params)

retrieve

public T retrieve(String path,
                  Map<String,String> params,
                  org.elasticsearch.common.path.PathTrie.TrieMatchingMode trieMatchingMode)

retrieveAll

public Iterator<T> retrieveAll(String path,
                               Supplier<Map<String,String>> paramSupplier)

Returns an iterator of the objects stored in the PathTrie, using all possible TrieMatchingMode modes. The paramSupplier is called between each invocation of next() to supply a new map of parameters.
