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 interfaceGenerator
- Returns:
- a set of
EventType
s.
-
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 interfaceOnExecutionGenerator
-
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 SQLinsert
orupdate
statement. For example, this method should return:true
if the value is generated by calling a SQL function likecurrent_timestamp
, orfalse
if the value is generated by a trigger, bygenerated always as
, or using a column default value.
- Specified by:
referenceColumnsInSql
in interfaceOnExecutionGenerator
- 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
ornextval('mysequence')
, or - syntactic markers like
default
.
- Specified by:
getReferencedColumnValues
in interfaceOnExecutionGenerator
- 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.
