determineDifferences	back to summary
public List<ComparisonDifference> determineDifferences(Object actual, Object expected, RecursiveComparisonConfiguration recursiveComparisonConfiguration) Compare two objects for differences by doing a 'deep' comparison. This will traverse the Object graph and perform either a field-by-field comparison on each object (if not .equals() method has been overridden from Object), or it will call the customized .equals() method if it exists. This method handles cycles correctly, for example A->B->C->A. Suppose a and a' are two separate instances of the A with the same values for all fields on A, B, and C. Then a.deepEquals(a') will return an empty list. It uses cycle detection storing visited objects in a Set to prevent endless loops. Parameters actual:Object Object one to compare expected:Object Object two to compare recursiveComparisonConfiguration:RecursiveComparisonConfiguration the recursive comparison configuration Returns:List<ComparisonDifference> the list of differences found or an empty list if objects are equivalent. Equivalent means that all field values of both subgraphs are the same, either at the field level or via the respectively encountered overridden .equals() methods during traversal.

determineDifferences

public List<ComparisonDifference> determineDifferences(Object actual, Object expected, RecursiveComparisonConfiguration recursiveComparisonConfiguration)

Compare two objects for differences by doing a 'deep' comparison. This will traverse the Object graph and perform either a field-by-field comparison on each object (if not .equals() method has been overridden from Object), or it will call the customized .equals() method if it exists.

This method handles cycles correctly, for example A->B->C->A. Suppose a and a' are two separate instances of the A with the same values for all fields on A, B, and C. Then a.deepEquals(a') will return an empty list. It uses cycle detection storing visited objects in a Set to prevent endless loops.

Parameters

actual:Object: Object one to compare
expected:Object: Object two to compare
recursiveComparisonConfiguration:RecursiveComparisonConfiguration: the recursive comparison configuration

Returns:List<ComparisonDifference>

the list of differences found or an empty list if objects are equivalent. Equivalent means that all field values of both subgraphs are the same, either at the field level or via the respectively encountered overridden .equals() methods during traversal.
