Method Detail
-
supports
public boolean supports(Database database)
Description copied from class:AbstractChange
Implementation delegates logic to theSqlGenerator.supports(liquibase.statement.SqlStatement, liquibase.database.Database)
method on theSqlStatement
objects returned byChange.generateStatements(liquibase.database.Database)
. If no or null SqlStatements are returned by generateStatements then this method returns true. IfAbstractChange.generateStatementsVolatile(liquibase.database.Database)
returns true, we cannot call generateStatements and so assume true.- Specified by:
supports
in interfaceChange
- Overrides:
supports
in classAbstractChange
-
getConfirmationMessage
public String getConfirmationMessage()
Description copied from interface:Change
Confirmation message to be displayed after the change is executed. Should include relevant configuration settings to make it as helpful as possible. This method may be called outside the changelog execution process, such as in documentation generation.
-
generateStatements
public SqlStatement[] generateStatements(Database database)
Description copied from interface:Change
Generates theSqlStatement
objects required to run the change for the given database. NOTE: This method may be called multiple times throughout the changelog execution process and may be called in documentation generation and other integration points as well. If this method reads from the current database state or uses any other logic that will be affected by whether previous changeSets have ran or not, you must return true fromChange.generateStatementsVolatile(liquibase.database.Database)
