Interface IQueryParamValuesProvider

All Superinterfaces:

quadbase.common.util.IQueryParamValuesProvider

public interface IQueryParamValuesProvider
extends quadbase.common.util.IQueryParamValuesProvider

A class implementing this interface should also implement IQueryInParam. This interface provides additional functionality to IQueryInParam. This interface allows the user to define a custom list of objects as possible values to the parameter.

The getSelectionChoices method is called only once during report initialization to get the vector of objects. Then this list is used any time the user is asked to choose a value. No subsequent call will be made to getSelectionChoices.

There are limitations to the type of objects that can be in the vector. More importantly, the objects should respect the SQL type of the parameter. The following is a table for the SQL type to object class mapping:

SQL Type	Java Object
java.sql.Types.CHAR java.sql.Types.VARCHAR java.sql.Types.LONGVARCHAR	java.lang.String
java.sql.Types.INTEGER	java.lang.Integer
java.sql.Types.SMALLINT	java.lang.Short
java.sql.Types.TINYINT	java.lang.Byte
java.sql.Types.BIGINT	java.lang.Long
java.sql.Types.FLOAT java.sql.Types.DOUBLE	java.lang.Double
java.sql.Types.REAL	java.lang.Float
java.sql.Types.NUMERIC java.sql.Types.DECIMAL	java.Math.BigDecimal
java.sql.Types.BIT	java.lang.Boolean
java.sql.Types.DATE	java.sql.Date
java.sql.Types.TIME	java.sql.TIME
java.slq.Types.TIMESTAMP	java.sql.TIMESTAMP

Only the data types listed above should be used.
