pub struct Graph { /* fields omitted */ }
A representation of a graph including node annotations and edges.
Edges are partioned into components and each component is implemented by specialized graph storage implementation.
Use the CorpusStorage struct to create and manage instances of a Graph
.
Graphs can have an optional location on the disk.
In this case, changes to the graph via the apply_update(...) function are automatically persisted to this location.
Get a read-only graph storage reference for the given component c
.
Returns all components of the graph given an optional type (ctype
) and name
.
This allows to filter which components to recieve.
If you want to retrieve all components, use None
as value for both arguments.
Return the annotation key which is used for the special annis::node_type
annotation which every node must have to mark its existance.
Get all annotations for an item
(node or edge).
Return the total number of annotations contained in this AnnotationStorage
.
Return the number of annotations contained in this AnnotationStorage
filtered by name
and optional namespace (ns
).
Returns an iterator for all items that exactly match the given annotation constraints. The annotation name
must be given as argument, the other arguments are optional. Read more
Returns an iterator for all items where the value matches the regular expression. The annotation name
and the pattern
for the value must be given as argument, the namespace
argument is optional and can be used as additional constraint. Read more
Estimate the number of results for an annotation exact search for a given an inclusive value range. Read more
Estimate the number of results for an annotation regular expression search for a given pattern. Read more
Return a list of all existing values for a given annotation key
. If the most_frequent_first
parameter is true, the results are sorted by their frequency. Read more
Get all the annotation keys which are part of this annotation storage
