Default Value Plug-ins

Default value plug-ins supply the default values used when no values are available. Default value plug-ins are provided for the following domains (all of the plug-ins are in the curam.util.client.domain.defaults package):

Table 1. Out-of-the-Box Default Value Plug-ins
Domain	Plug-in Class	Assumed Value	Displayed Value
SVR_BLOB	`SvrBlobDefault`	Empty BLOB	Empty BLOB
SVR_BOOLEAN	`SvrBooleanDefault`	False	False
SVR_CHAR	`SvrCharDefault`	Character zero	Character zero
SVR_DATE	`SvrDateDefault`	Zero date	Current date
SVR_DATETIME	`SvrDateTimeDefault`	Zero date-time	Current date-midnight
SVR_DATETIME	`SvrDateTimeDefaultCurrTime`	Zero date-time	Current date - Current time
SVR_DOUBLE	`SvrDoubleDefault`	Zero	Zero
SVR_FLOAT	`SvrFloatDefault`	Zero	Zero
SVR_INT8	`SvrInt8Default`	Zero	Zero
SVR_INT16	`SvrInt16Default`	Zero	Zero
SVR_INT32	`SvrInt32Default`	Zero	Zero
SVR_INT64	`SvrInt64Default`	Zero	Zero
SVR_MONEY	`SvrMoneyDefault`	Zero	Zero
SVR_STRING	`SvrStringDefault`	Empty string	Empty string
SVR_UNBOUNDED_STRING	`SvrStringDefault`	Empty string	Empty string
CODETABLE_CODE	`CodeTableCodeDefault`	Empty code string	Empty code string

Within the Cúram application, the zero date and time is represented as midnight on January 1,0001; this is interpreted as if no date and time has been set at all.

Also, the default value for a code-table code is an empty code string; a different mechanism is used to define default code-table codes during code-table administration.

SvrDateTimeDefault plug-in is time zone aware and the displayed value it returns is offset by the difference between the user and server time zones. The configured converter plug-in is expected to also consider time zone settings and offset the value accordingly. The end result is that the time part of date-time value is set to midnight regardless the time zone settings.
