Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`TSPLIBImporter.Specification`	`getSpecification()`	Returns the `TSPLIBImporter.Specification` instance containing all values from the specification part of a TSPLIB95 file.
`List<V>`	`getTour()`	Returns the `List` of vertices in the order of the tour defined in an imported TSPLIB95 file or null if no tour was imported.
`Map<V,TSPLIBImporter.Node>`	`getVertexToNodeMapping()`	Returns the mapping of vertex to corresponding node imported from the NODE_COORD_SECTION of a TSPLIB95 file.
`boolean`	`hasDistinctNeighborDistances()`	Returns true if for the imported graph each vertex all touching edges have different weights.
`boolean`	`hasDistinctNodeLocations()`	Returns true if for the imported graph all vertices have distinct coordinates and non of them have `equal` `coordinate values` , else false.

- Method Detail
  - getSpecification
```
public TSPLIBImporter.Specification getSpecification()
```
    Returns the TSPLIBImporter.Specification instance containing all values from the specification part of a TSPLIB95 file.
    
    Returns:
    
    the Specification of an imported TSPLIB95 file
  - getVertexToNodeMapping
```
public Map<V,TSPLIBImporter.Node> getVertexToNodeMapping()
```
    Returns the mapping of vertex to corresponding node imported from the NODE_COORD_SECTION of a TSPLIB95 file.
    
    Returns:
    
    the mapping of vertex to corresponding node
  - getTour
```
public List<V> getTour()
```
    Returns the List of vertices in the order of the tour defined in an imported TSPLIB95 file or null if no tour was imported.
    Note that a tour can be imported by TSPLIBImporter.importGraph(Graph, Reader) or TSPLIBImporter.importTour(Metadata, Reader) .
    
    Returns:
    
    the vertex tour from the file or null
  - hasDistinctNodeLocations
```
public boolean hasDistinctNodeLocations()
```
    Returns true if for the imported graph all vertices have distinct coordinates and non of them have equal coordinate values , else false.
    
    Returns:
    
    true if no equally located nodes were imported from the file, else false
    
    Throws:
    
    IllegalStateException - if no graph was imported
  - hasDistinctNeighborDistances
```
public boolean hasDistinctNeighborDistances()
```
    Returns true if for the imported graph each vertex all touching edges have different weights.
    If this method returns true this means for the TSP that for each location each other location has a different distance, so there are no two other locations that have the same distance from that location.
    
    Returns:
    
    true if all touching edges of each vertex have different weight, else false
    
    Throws:
    
    IllegalStateException - if no graph was imported
