com.crystaldecisions.sdk.occa.report.data.ExpressionValue
public class ExpressionValue
This object represents a value that needs to be evaluated. Examples of ExpressionValues are: 2+2, 3*4, {Customer.Last Year's Sales}.
Literal values, defined as values that do not need to be
evaluated, are stored using the
ConstantValue
Object.
The ExpressionValue
object is used by the
FieldRangeFilterItem
object
to store values in primitive expressions of filters.
Use the IExpressionValue
interface to get and set values for
the expression.

public java.lang.String computeText()
IValue
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.

public java.lang.String displayText(java.util.Locale locale)
IValue
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
.
