Examples with ModelComparator org.jumpmind.db.alter.ModelComparator used on opensource projects

Example 1 with ModelComparator

use of org.jumpmind.db.alter.ModelComparator in project symmetric-ds by JumpMind.

the class AbstractDdlBuilder method alterDatabase.

/**
     * Generates the DDL to modify an existing database so the schema matches
     * the specified database schema by using drops, modifications and
     * additions. Database-specific implementations can change aspect of this
     * algorithm by redefining the individual methods that compromise it.
