Method Details

findEquivalentObjects

public List<DbObject> findEquivalentObjects(DbObject rootObject,
 DbObject objToMatch)

Specified by:

findEquivalentObjects in interface ComparisonUtils

compareSimpleOrderedLists

public void compareSimpleOrderedLists(DbProperty refProp,
 DbProperty targetProp,
 DiffContext ctx)

Description copied from interface: ComparisonUtils

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.

Specified by:

compareSimpleOrderedLists in interface ComparisonUtils

Parameters:

refProp - DbProperty

targetProp - DbProperty

ctx - DiffContext

compareSimpleCollections

public void compareSimpleCollections(DbProperty leftProp,
 DbProperty rightProp,
 DiffContext ctx)

Description copied from interface: ComparisonUtils

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.

Specified by:

compareSimpleCollections in interface ComparisonUtils

Parameters:

leftProp - DbProperty

rightProp - DbProperty

ctx - - context

compareCollections

public void compareCollections(Collection<? extends DbObject> leftCollection,
 Collection<? extends DbObject> rightCollection,
 DiffContext ctx)

Description copied from interface: ComparisonUtils

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

Specified by:

compareCollections in interface ComparisonUtils

ctx - - context

compareSimple

public void compareSimple(DbProperty leftProperty,
 DbProperty rightProperty,
 DiffContext ctx)

Description copied from interface: ComparisonUtils

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

Specified by:

compareSimple in interface ComparisonUtils

Parameters:

leftProperty - DbProperty

rightProperty - DbProperty

ctx - - context
