public DependencyChecker(Analyser analyser,
                         java.lang.String dependencyDefinition,
                         java.util.Map<java.lang.Object,java.lang.Object> properties,
                         ResultRenderer renderer)
```
    Creates a new instance. Note, that the constructor does not create the graph. It only parses dependencyDefinition as a preprocessing step. The calculation of the graph is done in check(PrintWriter).
    
    Parameters:
    
    analyser - Analyzer instance.
    
    dependencyDefinition - Description (as read from a .ddf file) of the dependencies to be checked.
    
    renderer - Output renderer for unwanted dependencies found.
- Method Detail
  - check
```
public boolean check(java.io.PrintWriter writer)
```
    Checks the graph and write unwanted dependencies onto the specified writer.
    
    Returns:
    
    true if no unwanted dependency has been found.
  - check
```
public Result check()
```
    Checks the graph.
  - main
```
public static void main(java.lang.String[] args)
```
    Runs the DependencyChecker application. Exit 0 if no unwanted dependency found otherwise 1 is returned.
