```
public String getSqlMigrationSuffix()
```
    Retrieves the file name suffix for sql migrations.
    
    Returns:
    The file name suffix for sql migrations. (default: .sql)
  - isIgnoreFailedFutureMigration
```
public boolean isIgnoreFailedFutureMigration()
```
    Whether to ignore failed future migrations when reading the metadata table. These are migrations that were performed by a newer deployment of the application that are not yet available in this version. For example: we have migrations available on the classpath up to version 3.0. The metadata table indicates that a migration to version 4.0 (unknown to us) has already been attempted and failed. Instead of bombing out (fail fast) with an exception, a warning is logged and Flyway terminates normally. This is useful for situations where a database rollback is not an option. An older version of the application can then be redeployed, even though a newer one failed due to a bad migration.
    
    Returns:
    true to terminate normally and log a warning, false to fail fast with an exception. (default: false)
  - getValidationMode
```
@Deprecated
public com.googlecode.flyway.core.validation.ValidationMode getValidationMode()
```
    Deprecated. Use isValidateOnMigrate instead. Will be removed in Flyway 3.0.
    
    Retrieves the mode for validation. Only used for migrate. When using validate validationMode is always ALL.
    
    Returns:
    The mode for validation. (default: NONE)
  - getValidationErrorMode
```
@Deprecated
public com.googlecode.flyway.core.validation.ValidationErrorMode getValidationErrorMode()
```
    Deprecated. Use isCleanOnValidationError instead. Will be removed in Flyway 3.0.
    
    Retrieves the error mode for validation.
    
    Returns:
    The error mode for validation. (default: FAIL)
  - isValidateOnMigrate
```
public boolean isValidateOnMigrate()
```
    Whether to automatically call validate or not when running migrate.
    
    Returns:
    true if validate should be called. false if not. (default: false)
  - isCleanOnValidationError
```
public boolean isCleanOnValidationError()
```
    Whether to automatically call clean or not when a validation error occurs.
    
    This is exclusively intended as a convenience for development. Even tough we strongly recommend not to change migration scripts once they have been checked into SCM and run, this provides a way of dealing with this case in a smooth manner. The database will be wiped clean automatically, ensuring that the next migration will bring you back to the state checked into SCM.
    
    Warning ! Do not enable in production !
    
    Returns:
    true if clean should be called. false if not. (default: false)
  - getInitialVersion
```
@Deprecated
public MigrationVersion getInitialVersion()
```
    Deprecated. Use getInitVersion() instead. Will be removed in Flyway 3.0.
    
    Retrieves the version to tag an existing schema with when executing init.
    
    Returns:
    The version to tag an existing schema with when executing init. (default: 1)
  - getInitialDescription
```
@Deprecated
public String getInitialDescription()
```
    Deprecated. Use getInitDescription() instead. Will be removed in Flyway 3.0.
    
    Retrieves the description to tag an existing schema with when executing init.
    
    Returns:
    The description to tag an existing schema with when executing init. (default: << Flyway Init >>)
  - getInitVersion
```
public MigrationVersion getInitVersion()
```
    Retrieves the version to tag an existing schema with when executing init.
    
    Returns:
    The version to tag an existing schema with when executing init. (default: 1)
  - getInitDescription
```
public String getInitDescription()
```
    Retrieves the description to tag an existing schema with when executing init.
    
    Returns:
    The description to tag an existing schema with when executing init. (default: << Flyway Init >>)
  - isDisableInitCheck
```
@Deprecated
public boolean isDisableInitCheck()
```
    Deprecated. Use initOnMigrate instead. Will be removed in Flyway 3.0.
    
    Flag to disable the check that a non-empty schema has been properly initialized with init. This check ensures Flyway does not migrate or clean the wrong database in case of a configuration mistake. Be careful when disabling this!
    
    Returns:
    true if the check is disabled. false if it is active. (default: false)
  - isInitOnMigrate
```
public boolean isInitOnMigrate()
```
    Whether to automatically call init when migrate is executed against a non-empty schema with no metadata table. This schema will then be initialized with the initialVersion before executing the migrations. Only migrations above initialVersion will then be applied.
    
    This is useful for initial Flyway production deployments on projects with an existing DB.
    
    Be careful when enabling this as it removes the safety net that ensures Flyway does not migrate the wrong database in case of a configuration mistake!
    
    Returns:
    true if init should be called on migrate for non-empty schemas, false if not. (default: false)
  - isOutOfOrder
```
public boolean isOutOfOrder()
```
    Allows migrations to be run "out of order".
    If you already have versions 1 and 3 applied, and now a version 2 is found, it will be applied too instead of being ignored.
    
    Returns:
    true if outOfOrder migrations should be applied, false if not. (default: false)
  - getDataSource
```
public DataSource getDataSource()
```
    Retrieves the dataSource to use to access the database. Must have the necessary privileges to execute ddl.
    
    Returns:
    The dataSource to use to access the database. Must have the necessary privileges to execute ddl.
  - setIgnoreFailedFutureMigration
```
public void setIgnoreFailedFutureMigration(boolean ignoreFailedFutureMigration)
```
    Ignores failed future migrations when reading the metadata table. These are migrations that were performed by a newer deployment of the application that are not yet available in this version. For example: we have migrations available on the classpath up to version 3.0. The metadata table indicates that a migration to version 4.0 (unknown to us) has already been attempted and failed.
