AddColumnGeneratorSQLite

public AddColumnGeneratorSQLite()

Method Details

validate

public ValidationErrors validate(AddColumnStatement statement,
 Database database,
 SqlGeneratorChain sqlGeneratorChain)

Description copied from interface: SqlGenerator

Validate the data contained in the SqlStatement. If there are no errors, return an empty ValidationErrors object, not a null value. Liquibase will inspect the ValidationErrors result before attempting to call generateSql.

Specified by:

validate in interface SqlGenerator<AddColumnStatement>

Overrides:

validate in class AddColumnGenerator

generateStatementsIsVolatile

public boolean generateStatementsIsVolatile(Database database)

Description copied from interface: SqlGenerator

Does this change require access to the database metadata? If true, the change cannot be used in an updateSql-style command.

Specified by:

generateStatementsIsVolatile in interface SqlGenerator<AddColumnStatement>

Overrides:

generateStatementsIsVolatile in class AbstractSqlGenerator<AddColumnStatement>

supports

public boolean supports(AddColumnStatement statement,
 Database database)

Description copied from interface: SqlGenerator

Does this generator support the given statement/database combination? Do not validate the statement with this method, only return if it can support it.

Specified by:

supports in interface SqlGenerator<AddColumnStatement>

Overrides:

supports in class AbstractSqlGenerator<AddColumnStatement>

generateSql

public Sql[] generateSql(AddColumnStatement statement,
 Database database,
 SqlGeneratorChain sqlGeneratorChain)

Description copied from interface: SqlGenerator

Generate the actual Sql for the given statement and database.

Specified by:

generateSql in interface SqlGenerator<AddColumnStatement>

Overrides:

generateSql in class AddColumnGenerator

getPriority

public int getPriority()

Description copied from interface: SqlGenerator

Of all the SqlGenerators that "support" a given SqlStatement/Database, SqlGeneratorFactory will return the one with the highest priority.

Specified by:

getPriority in interface PrioritizedService

Specified by:

getPriority in interface SqlGenerator<AddColumnStatement>

Overrides:

getPriority in class AbstractSqlGenerator<AddColumnStatement>
