```
org.gcube.data.trees.data.Tree add(org.gcube.data.trees.data.Tree tree)
                                   throws InvalidTreeException
```
    Adds a Tree to the bound source.
    
    Parameters:
    tree - the tree
    
    Returns:
    a tree that models the outcome of adding the tree in input. If not otherwise documented, the outcome is the input tree with modifications made at the point of addition to the source, if any.
    
    Throws:
    
    InvalidTreeException - if the tree does not conform to the data type of the source or if it is invalid for addition
    
    org.gcube.common.clients.exceptions.DiscoveryException - if the proxy is created in discovery mode but no service endpoints could be discovered
    
    org.gcube.common.clients.exceptions.UnsupportedOperationException - if the bound source does not support the operation
    
    org.gcube.common.clients.exceptions.UnsupportedRequestException - if the bound source does not support this particular request
    
    org.gcube.common.clients.exceptions.ServiceException - if the call fails for any other error
  - add
```
org.gcube.data.streams.Stream<org.gcube.data.trees.data.Tree> add(org.gcube.data.streams.Stream<org.gcube.data.trees.data.Tree> trees)
```
    Adds one or more Trees to the bound source.
    
    Parameters:
    trees - a Stream of Trees
    
    Returns:
    a Stream of added Trees
    
    Throws:
    
    org.gcube.common.clients.exceptions.DiscoveryException - if, in discovery mode, there is no service for the bound source
    
    org.gcube.common.clients.exceptions.UnsupportedOperationException - if the bound source does not support the operation
    
    org.gcube.common.clients.exceptions.UnsupportedRequestException - if the bound source does not support this particular request
    
    org.gcube.common.clients.exceptions.ServiceException - if the call fails for any other error
  - add
```
org.gcube.data.streams.Stream<org.gcube.data.trees.data.Tree> add(URI locator)
```
    Adds one or more Trees to the bound source.
    
    Parameters:
    locator - a locator to a resultset of Trees
    
    Returns:
    a Stream of added Trees
    
    Throws:
    
    org.gcube.common.clients.exceptions.DiscoveryException - if, in discovery mode, there is no service for the bound source
    
    org.gcube.common.clients.exceptions.UnsupportedOperationException - if the bound source does not support the operation
    
    org.gcube.common.clients.exceptions.UnsupportedRequestException - if the bound source does not support this particular request
    
    org.gcube.common.clients.exceptions.ServiceException - if the call fails for any other error
  - update
```
org.gcube.data.trees.data.Tree update(org.gcube.data.trees.data.Tree delta)
                                      throws InvalidTreeException,
                                             UnknownTreeException
```
    Updates a tree in the bound source.
    
    Parameters:
    delta - the delta tree that captures the update
    
    Returns:
    a tree that models the outcome of updating the tree in input. If not otherwise documented, the outcome is the input tree with modifications made at the point of update, if any.
    
    Throws:
    
    UnknownTreeException - if the delta tree does not identify a tree in the source
    
    InvalidTreeException - if the delta tree is invalid
    
    org.gcube.common.clients.exceptions.DiscoveryException - if the proxy is created in discovery mode but no service endpoints could be discovered
    
    org.gcube.common.clients.exceptions.UnsupportedOperationException - if the bound source does not support the operation
    
    org.gcube.common.clients.exceptions.UnsupportedRequestException - if the bound source does not support this particular request
    
    org.gcube.common.clients.exceptions.ServiceException - if the call fails for any other error
  - update
```
org.gcube.data.streams.Stream<org.gcube.data.trees.data.Tree> update(org.gcube.data.streams.Stream<org.gcube.data.trees.data.Tree> deltas)
```

    Returns:
    a Stream of updated trees Trees
    
    Throws:
    
    org.gcube.common.clients.exceptions.DiscoveryException - if, in discovery mode, there is no service for the bound source
    
    org.gcube.common.clients.exceptions.UnsupportedOperationException - if the bound source does not support the operation
    
    org.gcube.common.clients.exceptions.UnsupportedRequestException - if the bound source does not support this particular request
    
    org.gcube.common.clients.exceptions.ServiceException - if the call fails for any other error
  - update
