getDefaultWidth

public int getDefaultWidth()

Description copied from interface: DataPersister

Return the default width associated with this type or 0 if none.

Specified by:

getDefaultWidth in interface DataPersister

Overrides:

javaToSqlArg

public Object javaToSqlArg(FieldType fieldType,
                           Object javaObject)

Description copied from interface: FieldConverter

Convert a Java object and return the appropriate argument to a SQL insert or update statement.

Specified by:

javaToSqlArg in interface FieldConverter

Overrides:

javaToSqlArg in class BaseFieldConverter

parseDefaultString

public Object parseDefaultString(FieldType fieldType,
                                 String defaultStr)
                          throws SQLException

Description copied from interface: FieldConverter

Convert a default string object and return the appropriate argument to a SQL insert or update statement.

Returns:

Result object to insert if the field is not specified or null if none.

Throws:

SQLException

resultToSqlArg

public Object resultToSqlArg(FieldType fieldType,
                             DatabaseResults results,
                             int columnPos)
                      throws SQLException

Description copied from interface: FieldConverter

Return the SQL argument object extracted from the results associated with column in position columnPos. For example, if the type is a date-long then this will return a long value or null.
