Detailed Description

The MV.Date data type class represents a MultiValue date.

The MultiValue start date is 01/01/1968
ObjectScript date is 01/01/1841

To convert an ObjectScript date ($h) to a MultiValue date:
MVdate = ObjectScript date - 46385

To convert a MultiValue date to an ObjectScript date:
ObjectScript date = MVdate + 46385

Member Function Documentation

DisplayToLogical()

_.MV.Date DisplayToLogical (   _, _.Library.String  val  )

static

Converts the input value val, which represents a date, into an MV Date format.

Returns the logical (MV Date) value of the input string val.

IsValid()

_.Library.Status IsValid (   _, _.Library.RawString  val  )

static

Tests if the logical value val, which represents a date in MV Date format,.

is valid. The validation is based on the class parameter settings used for the class attribute this data type is associated with. In this case, MAXVAL and MINVAL.

LogicalToDisplay()

_.Library.String LogicalToDisplay (   _, _.Library.Date  val  )

static

Converts the value of val, which is in logical MV Date format, into a display string.

The formatting is based on the value of the FORMAT parameter.

Returns the formatted value of val.

LogicalToOdbc()

_.Library.String LogicalToOdbc (   _, _.MV.Date  val  )

static

Converts val, which represents a date in logical MV Date format, into ODBC date format.

Returns the ODBC date string for the logical (MV Date) value val.

OdbcToLogical()

_.MV.Date OdbcToLogical (   _, _.Library.String  val  )

static

Converts val, which represents a date in ODBC format, into MV Date format.

Returns the MV Date value of the ODBC date string val.

Member Data Documentation

DISPLAYLIST

DISPLAYLIST = None

static

Used for enumerated (multiple-choice) attributes.

Used in conjunction with the VALUELIST parameter for enumerated (multiple-choice) attributes. DISPLAYLIST, if not null, represents the display values for the attribute corresponding with the logical values listed in VALUELIST.

The display values are returned by the LogicalToDisplay method.

FORMAT

FORMAT = None

static

The format specification for the data type's display value.

The value of the FORMAT parameter corresponds to the available parameters of the $ZDATE and $ZDATEH functions, which are used to perform the formatting.

VALUELIST

VALUELIST = None

static

Used for enumerated (multiple-choice) attributes.

VALUELIST is either a null string ("") or a delimiter separated list (where the delimiter is the first character) of logical values. If a non-null value is present, then the attribute is restricted to values in the list, and the validation code simply checks to see if the value is in the list.
