SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
This interface is used as a base class to represent different kinds of values (values in formulas, parameters, and so on). It is not to be used directly, and the actual value is defined in the implementing class.

of the field value that can be used in a report formula.

Method Detail |
public java.lang.String computeText()
The computeText
method returns a String
representation
of the field value that can be used in a report formula.
The String
is not formatted or localized.
The syntax will always be Crystal syntax.
If the field contains a date, computeText
returns Date(x, x, x); if it contains a date and time,
computeText
returns DateTime(x, x, x, x, x, x).
However, when the date is 1900, 0, 1 (the Java start date),
ComputeText returns Time(x, x, x). If you want to set a field
to a time value only (that is, with no date), you should set
the date to 1900, 0, 1, so that computeText
will retrieve
the correct information.
String
representation
of the field value that can be used in a report formula.public java.lang.String displayText(java.util.Locale locale)
Returns the field's value as a localized and formatted
String
. The Locale can be a java.util.Locale
value.
The value is formatted according to the locale.
The user is required to pass in a locale; the system
default locale or user default locale is not used.
If the field contains a date, displayText
returns a
locale-specific date string; if it contains a date and time,
displayText
returns a locale-specific date time String
;
if it contains a time String
, displayText
returns a locale-specific
time String
.
locale
- The locale as specified by
java.util.Locale
.
String
