DataTypeGraphComparator

java.lang.Object
- ghidra.app.util.bin.format.dwarf4.next.DataTypeGraphComparator

```
public class DataTypeGraphComparator
extends java.lang.Object
```
Compares two DataType directed graphs, calling a method that can observe each DataType pair that occupy equivalent positions in each graph.
The first/left DataType graph is assumed to be composed of DataTypeImpl instances, and the second/right DataType graph is assumed to be composed of DataType DB instances.
Only DataTypes in the left graph are followed and may lead to a possible match with the right graph.
This class is used to help transfer mappings that point to impl DataTypes to also point them at the resultant 'db' DataTypes that are created by the DataTypeManager.

public static void compare(DataType preDT,
                           DataType postDT,
                           DataTypeGraphComparator.DataTypePairObserver observer)
```
    Compares two datatypes graphs, calling the observer callback for each paired DataType that occupy equivalent positions in each graph.
    
    Parameters:
    
    preDT - - Original (impl) DataType from before submitting to DataTypeManager.
    
    postDT - - Result DataType from the DataTypeManager
    
    observer - - Callback called for each position in the preDT graph that has a matching position in the postDT graph.
