CreateIndexChange

public CreateIndexChange()

Method Detail

getIndexName

public String getIndexName()

setIndexName

public void setIndexName(String indexName)

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 the ColumnConfig objects defined for this Change

Specified by:

getColumns in interface ChangeWithColumns<AddColumnConfig>

setColumns

public void setColumns(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>

getTablespace

public String getTablespace()

setTablespace

public void setTablespace(String tablespace)

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.

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 interface Change

Overrides:

checkStatus in class AbstractChange

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 interface Change

setUnique

public void setUnique(Boolean isUnique)

Parameters:

isUnique - the isUnique to set

isUnique

public Boolean isUnique()

getAssociatedWith

public String getAssociatedWith()

Returns:

Index associations. Valid values:

primaryKey

foreignKey

uniqueConstraint

none

setAssociatedWith

public void setAssociatedWith(String associatedWith)

getCatalogName

public String getCatalogName()

setCatalogName

public void setCatalogName(String catalogName)

getClustered

public Boolean getClustered()

setClustered

public void setClustered(Boolean clustered)

getSerializedObjectNamespace

public String getSerializedObjectNamespace()

Specified by:

getSerializedObjectNamespace in interface LiquibaseSerializable

Overrides:

getSerializedObjectNamespace in class AbstractChange

getSerializableFieldValue

public Object getSerializableFieldValue(String field)

Specified by:

getSerializableFieldValue in interface LiquibaseSerializable

Overrides:

getSerializableFieldValue in class AbstractChange

validate

public ValidationErrors validate(Database database)

Description copied from class: AbstractChange

Implementation checks the ChangeParameterMetaData for declared required fields and also delegates logic to the SqlGenerator.validate(liquibase.statement.SqlStatement, liquibase.database.Database, liquibase.sqlgenerator.SqlGeneratorChain) method on the SqlStatement objects returned by Change.generateStatements(liquibase.database.Database). If no or null SqlStatements are returned by generateStatements then this method returns no errors. If there are no parameters than this method returns no errors

Specified by:

validate in interface Change

Overrides:

validate in class AbstractChange
