Method Detail

add

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)

Updates one or more Trees in the bound source.

Parameters:

deltas - a Stream of delta Trees

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

Parameters:

locator - a locator to a resultset of delta Trees

Returns:

a Stream of updated 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
