Method Summary

Methods

Modifier and Type	Method and Description
void	compareCollections(java.util.Collection leftCollection, java.util.Collection rightCollection, DiffContext ctx) Compare collections of DbObjects using their DbObject#diff(DbObject, Differences) method.
void	compareSimple(DbProperty left, DbProperty right, DiffContext ctx) Compare two 'simple' (i.e.
void	compareSimpleCollections(DbProperty leftProperty, DbProperty rightProperty, DiffContext ctx) Compare two collections.
void	compareSimpleOrderedLists(DbProperty leftProperty, DbProperty rightProperty, DiffContext ctx) Compare two Lists of 'simple' (i.e.
java.util.List	findEquivalentObjects(DbObject rootObject, DbObject objToMatch)

Method Detail

findEquivalentObjects

java.util.List findEquivalentObjects(DbObject rootObject,
                                   DbObject objToMatch)

compareSimpleOrderedLists

void compareSimpleOrderedLists(DbProperty leftProperty,
                             DbProperty rightProperty,
                             DiffContext ctx)

Compare two Lists of 'simple' (i.e. non-DbObject) objects. Ordering is significant - if an element E appears in both collections but at different indexes then it is not considered to be the same item.

Parameters:

leftProperty -

rightProperty -

ctx -

compareSimpleCollections

void compareSimpleCollections(DbProperty leftProperty,
                            DbProperty rightProperty,
                            DiffContext ctx)

Compare two collections. Similar to ComparisonUtils.compareSimpleOrderedLists(DbProperty, DbProperty, DiffContext) except that this method operates on Collections and order (and cardinality) is not important. If an element E from the reference collection appears one or more times at any position in the target collection then that element is said to be in both with no difference.

Parameters:

leftProperty -

rightProperty -

ctx -

compareCollections

void compareCollections(java.util.Collection leftCollection,
                      java.util.Collection rightCollection,
                      DiffContext ctx)

Compare collections of DbObjects using their DbObject#diff(DbObject, Differences) method.

Parameters:

leftCollection -

rightCollection -

differences -

compareSimple

void compareSimple(DbProperty left,
                 DbProperty right,
                 DiffContext ctx)

Compare two 'simple' (i.e. non-DbObject) objects using their Object.equals(Object) method to decide if there is a difference.

Parameters:

left -

right -

differences -
