Creates a diff tree comparing two database schemas.

Parameters:

settings - the compare settings

left - the left (old) database schema

right - the right (new) database schema

Returns:

the root TreeElement representing the diff tree

Throws:

InterruptedException - if the operation is interrupted

create

public static TreeElement create(ISettings settings,
 AbstractDatabase left,
 AbstractDatabase right,
 IMonitor monitor)
                          throws InterruptedException

Creates a diff tree comparing two database schemas with progress monitoring.

Parameters:

settings - the compare settings

left - the left (old) database schema

right - the right (new) database schema

monitor - the progress monitor for tracking operation progress

Returns:

the root TreeElement representing the diff tree

Throws:

InterruptedException - if the operation is interrupted

addColumns

@Deprecated
public static void addColumns(List<AbstractColumn> left,
 List<AbstractColumn> right,
 TreeElement parent,
 List<TreeElement> list)

Deprecated.

this method is deprecated

Adds column differences to the tree element list.

Parameters:

left - the left (old) column list

right - the right (new) column list

parent - the parent tree element

list - the list to add column differences to

getTablesWithChangedColumns

public static Set<TreeElement> getTablesWithChangedColumns(AbstractDatabase oldDbFull,
 AbstractDatabase newDbFull,
 List<TreeElement> selected)

Gets tables that have changed columns from the selected elements.

Parameters:

oldDbFull - the old database schema

newDbFull - the new database schema

selected - the list of selected tree elements

Returns:

a set of table elements that have changed columns

createTree

public TreeElement createTree(AbstractDatabase left,
 AbstractDatabase right)
                       throws InterruptedException

Creates a diff tree by comparing two database schemas and building a hierarchical tree structure representing the differences between them.

Parameters:

left - the left (old) database schema to compare

right - the right (new) database schema to compare

Returns:

the root TreeElement representing the complete diff tree with "Database" as the root node and all schema differences as child nodes

Throws:
