Expand description

Return the copy of a subgraph which includes all nodes that belong to any of the given list of sub-corpus/document identifiers.

  • ptr - The corpus storage object.
  • corpus_name - The name of the corpus for which the subgraph should be generated from.
  • corpus_ids - A set of sub-corpus/document identifiers describing the subgraph.
  • err - Pointer to a list of errors. If any error occured, this list will be non-empty.
