GeneratedAlwaysGeneration

public GeneratedAlwaysGeneration()

Method Details

getEventTypes

public EnumSet<EventType> getEventTypes()

Description copied from interface: Generator

The event types for which this generator should be called to produce a new value.

Identifier generators must return EventTypeSets.INSERT_ONLY.

Specified by:

getEventTypes in interface Generator

Returns:

a set of EventTypes.

writePropertyValue

public boolean writePropertyValue()

Description copied from interface: OnExecutionGenerator

Determines if the property values are written to JDBC as the argument of a JDBC ? parameter.

Specified by:

writePropertyValue in interface OnExecutionGenerator

referenceColumnsInSql

public boolean referenceColumnsInSql(Dialect dialect)

Description copied from interface: OnExecutionGenerator

Determines if the columns whose values are generated are included in the column list of the SQL insert or update statement. For example, this method should return:

• true if the value is generated by calling a SQL function like current_timestamp, or
• false if the value is generated by a trigger, by generated always as, or using a column default value.

Specified by:

referenceColumnsInSql in interface OnExecutionGenerator

Returns:

true if the column is included in the column list of the SQL statement.

getReferencedColumnValues

public String[] getReferencedColumnValues(Dialect dialect)

Description copied from interface: OnExecutionGenerator

A SQL expression indicating how to calculate the generated values when the mapped columns are included in the SQL statement. The SQL expressions might be:

• function calls like current_timestamp or nextval('mysequence'), or
• syntactic markers like default.

Specified by:

getReferencedColumnValues in interface OnExecutionGenerator

Parameters:

dialect - The SQL dialect, allowing generation of an expression in dialect-specific SQL.

Returns:

The column value to be used in the generated SQL statement.
