Constructor Detail

SortedIdMergeIterator

public SortedIdMergeIterator(Collection<OsmIdIterator> inputs)
                      throws IOException

Merge the elements from a collection of OSM input sources to a single OSM input source. The merging algorithm expects the input data to be in default order, i.e. a sequence of nodes, followed by a sequence of ways, followed by a sequence of relations. Each sequence ordered by their object's identifiers.

Parameters:

inputs - a collection of iterators to retrieve data from.

Throws:

IOException
