getCatalogName
public String getCatalogName()
-
setCatalogName
public void setCatalogName(String catalogName)
-
getSchemaName
public String getSchemaName()
-
setSchemaName
public void setSchemaName(String schemaName)
-
getTableName
public String getTableName()
-
setTableName
public void setTableName(String tableName)
-
getColumns
public List<AddColumnConfig> getColumns()
Description copied from interface:ChangeWithColumns
Return all theColumnConfig
objects defined for thisChange
- Specified by:
getColumns
in interfaceChangeWithColumns<AddColumnConfig>
-
setColumns
public void setColumns(List<AddColumnConfig> columns)
- Specified by:
setColumns
in interfaceChangeWithColumns<AddColumnConfig>
-
addColumn
public void addColumn(AddColumnConfig column)
Description copied from interface:ChangeWithColumns
Add a column configuration to the Change.- Specified by:
addColumn
in interfaceChangeWithColumns<AddColumnConfig>
-
removeColumn
public void removeColumn(ColumnConfig column)
-
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)
.- Specified by:
generateStatements
in interfaceChange
-
createInverses
protected Change[] createInverses()
Description copied from class:AbstractChange
Create inverse changes that can roll back this change. This method is intended to be overridden by Change implementations that have a logical inverse operation. Default implementation returns null. IfAbstractChange.generateRollbackStatements(liquibase.database.Database)
is overridden, this method may not be called.- Overrides:
createInverses
in classAbstractChange
- 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.
- See Also:
#supportsRollback
-
checkStatus
public ChangeStatus checkStatus(Database database)
Description copied from interface:Change
Validate that this change executed successfully against the given database. This will check that the update completed at a high level plus check details of the change. For example, a change to add a column will check that the column exists plus data type, default values, etc.- Specified by:
checkStatus
in interfaceChange
- Overrides:
checkStatus
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.- Specified by:
getConfirmationMessage
in interfaceChange
-
getSerializedObjectNamespace
public String getSerializedObjectNamespace()
- Specified by:
getSerializedObjectNamespace
in interfaceLiquibaseSerializable
- Overrides:
getSerializedObjectNamespace
in classAbstractChange
-
modify
public void modify(ChangeVisitor changeVisitor) throws ParsedNodeException
- Specified by:
modify
in interfaceChange
- Overrides:
modify
in classAbstractChange
- Throws:
ParsedNodeException
- if there is an error processing ChangeVisitor
