Method Detail

getPriority

public int getPriority()

Informs the SqlGeneratorFactory that we are the preferred generator for CREATE INDEX statements in a Firebird database.

Specified by:

getPriority in interface PrioritizedService

Specified by:

getPriority in interface SqlGenerator<CreateIndexStatement>

Overrides:

getPriority in class AbstractSqlGenerator<CreateIndexStatement>

Returns:

The PRIORITY_DATABASE priority

supports

public boolean supports(CreateIndexStatement statement,
                        Database database)

Informs the SqlGeneratorFactory that we this class works on Firebird SQL databases only.

Specified by:

supports in interface SqlGenerator<CreateIndexStatement>

Overrides:

supports in class AbstractSqlGenerator<CreateIndexStatement>

Parameters:

statement - The SqlStatement object (ignored in this case)

database - The database object to be compared

Returns:

true if database is a Firebird database, else in other cases.

generateSql

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

Generate a CREATE INDEX SQL statement for Firebird databases.

Specified by:

generateSql in interface SqlGenerator<CreateIndexStatement>

Overrides:

generateSql in class CreateIndexGenerator

Parameters:

statement - A CreateIndexStatement with the desired properties of the SQL to be generated

database - A database object (must be of FirebirdDatabase type, or we will error out)

sqlGeneratorChain - The other generators in the current chain (ignored by this implementation)

Returns:

An array with one entry containing the generated CREATE INDEX statement for Firebird.

validate

public ValidationErrors validate(CreateIndexStatement createIndexStatement,
                                 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<CreateIndexStatement>

Overrides:

validate in class CreateIndexGenerator
