ExtractLineByLocation

public ExtractLineByLocation(Geometry line)

Method Detail
- extract
```
public static Geometry extract(Geometry line,
                               LinearLocation start,
                               LinearLocation end)
```
  Computes the subline of a LineString between two LinearLocations on the line. If the start location is after the end location, the computed linear geometry has reverse orientation to the input line.
  
  Parameters:
  
  line - the line to use as the baseline
  
  start - the start location
  
  end - the end location
  
  Returns:
  
  the extracted subline
- extract
```
public Geometry extract(LinearLocation start,
                        LinearLocation end)
```
  Extracts a subline of the input. If end < start the linear geometry computed will be reversed.
  
  Parameters:
  
  start - the start location
  
  end - the end location
  
  Returns:
  
  a linear geometry
- reverse
```
private Geometry reverse(Geometry linear)
```
- computeLine
```
private LineString computeLine(LinearLocation start,
                               LinearLocation end)
```
  Assumes input is valid (e.g. start <= end)
  
  Parameters:
  
  start -
  
  end -
  
  Returns:
  
  a linear geometry
- computeLinear
```
private Geometry computeLinear(LinearLocation start,
                               LinearLocation end)
```
  Assumes input is valid (e.g. start <= end)
  
  Parameters:
  
  start -
  
  end -
  
  Returns:
  
  a linear geometry
