public final class PlaceholderExpression extends TypedExpression
TypedExpression that represents a placeholder for a measure value. A PlaceholderExpression is similar to a SQL bind variable. An application gets a PlaceholderExpression by using one of the static constants of this class, such as PlaceholderExpression.TEXT_MEASURE.| Modifier and Type | Field and Description |
|---|---|
static PlaceholderExpression |
DATE_MEASURE
A constant that represents a measure that has date values.
|
static PlaceholderExpression |
MEASURE
A constant that represents a measure that has number values.
|
static PlaceholderExpression |
TEXT_MEASURE
A constant that represents a measure that has text values.
