getCatalogName

setCatalogName

public void setCatalogName(java.lang.String catalogName)

getSchemaName

public java.lang.String getSchemaName()

setSchemaName

public void setSchemaName(java.lang.String schemaName)

getTableName

public java.lang.String getTableName()

setTableName

public void setTableName(java.lang.String tableName)

getColumns

public java.util.List<AddColumnConfig> getColumns()

Description copied from interface: ChangeWithColumns

Return all the ColumnConfig objects defined for this Change

Specified by:

getColumns in interface ChangeWithColumns<AddColumnConfig>

setColumns

public void setColumns(java.util.List<AddColumnConfig> columns)

Specified by:

setColumns in interface ChangeWithColumns<AddColumnConfig>

addColumn

public void addColumn(AddColumnConfig column)

Description copied from interface: ChangeWithColumns

Add a column configuration to the Change.

Specified by:

addColumn in interface ChangeWithColumns<AddColumnConfig>

removeColumn

public void removeColumn(ColumnConfig column)

generateStatements

public SqlStatement[] generateStatements(Database database)

Description copied from interface: Change

Generates the SqlStatement 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 from Change.generateStatementsVolatile(liquibase.database.Database).

Specified by:

generateStatements in interface Change

createInverses

protected Change[] createInverses()

Description copied from class: AbstractChange

Create inverse changes that can roll back this change. This method is intended to be overriden by Change implementations that have a logical inverse operation. Default implementation returns null.

If AbstractChange.generateRollbackStatements(liquibase.database.Database) is overridden, this method may not be called.

Overrides:

createInverses in class AbstractChange

Returns:

Return null if there is no corresponding inverse and therefore automatic rollback is not possible. Return an empty array to have a no-op rollback.

getConfirmationMessage

public java.lang.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.

Specified by:

getConfirmationMessage in interface Change

getSerializedObjectNamespace

public java.lang.String getSerializedObjectNamespace()

Specified by:

getSerializedObjectNamespace in interface LiquibaseSerializable

Overrides:

getSerializedObjectNamespace in class AbstractChange
