PartialIdMap (core 2.2.0-alpha04 API)

All Known Subinterfaces:

CSRGraph, FilteredIdMap, Graph, IdMap

All Known Implementing Classes:

ArrayIdMap, CSRGraphAdapter, GraphAdapter, HugeGraph, IdMapAdapter, LabeledIdMap, NodeFilteredGraph, UnionGraph
```
public interface PartialIdMap
```
This interface exposes the relevant parts of IdMap used for relationship loading. It helps implementations that are only used for relationship loading to avoid implementing unnecessary methods.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.util.OptionalLong`	`rootNodeCount()`	Number of mapped node ids in the root mapping.
`long`	`toMappedNodeId(long originalNodeId)`	Maps an original node id to a mapped node id.

- Method Detail
  - toMappedNodeId
```
long toMappedNodeId(long originalNodeId)
```
    Maps an original node id to a mapped node id. In case of nested id maps, the mapped node id is always in the space of the innermost mapping.
    
    Parameters:
    
    originalNodeId - must be smaller or equal to the id returned by IdMap.highestNeoId()
  - rootNodeCount
```
java.util.OptionalLong rootNodeCount()
```
    Number of mapped node ids in the root mapping. This is necessary for nested (filtered) id mappings.
