```
public interface PathLabelGenerator
extends Serializable
```
PathLabelGenerator: interface to infer the label of a file directly from the path of a file
Example: /negative/file17.csv -> class "0"; /positive/file116.csv -> class "1" etc.
Though note that the output is a writable, hence it need not be numerical.

For use cases where multiple Writables are required (for example, networks with mixed classification/regression, or multiple output layers) use PathMultiLabelGenerator instead.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`Writable`	`getLabelForPath(String path)`
`Writable`	`getLabelForPath(URI uri)`
`boolean`	`inferLabelClasses()` If true: infer the set of possible label classes, and convert these to integer indexes.

- Method Detail
  - getLabelForPath
```
Writable getLabelForPath(String path)
```
  - getLabelForPath
```
Writable getLabelForPath(URI uri)
```
  - inferLabelClasses
```
boolean inferLabelClasses()
```
    If true: infer the set of possible label classes, and convert these to integer indexes. If when true, the returned Writables should be text writables.
    
    For regression use cases (or PathLabelGenerator classification instances that do their own label -> integer assignment), this should return false.
    
    Returns:
    
    whether label classes should be inferred
