get

public org.gcube.data.trees.data.Tree get(String id,
                                 org.gcube.data.trees.patterns.Pattern pattern)
                                   throws org.gcube.data.tmf.api.exceptions.UnknownTreeException,
                                          org.gcube.data.tmf.api.exceptions.InvalidTreeException

Returns a tree in the store with a given identifier, after pruning it with a given pattern.

Specified by:

get in interface SpeciesStore

Parameters:

id - the identifier

pattern - the pattern

Returns:

the tree

Throws:

org.gcube.data.tmf.api.exceptions.UnknownTreeException - if the store does not contain a tree with the given identifier

org.gcube.data.tmf.api.exceptions.InvalidTreeException - if the Tree with the the given identifier does not match the Pattern

get

public Iterator<org.gcube.data.trees.data.Tree> get(org.gcube.data.trees.patterns.Pattern pattern)

Returns all the trees in the store which match a given pattern, after pruning them with it.

Specified by:

Specified by:

add in interface SpeciesStore

Parameters:

treeStream - the stream of trees

Returns:

a stream of outcomes, one per tree in the input stream and in the same relative order.
