FunctionArgument

public final class PlaceholderExpression
extends TypedExpression

A 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.


Field Summary
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.

 

Method Summary
 java.lang.Object visit(SyntaxObjectVisitor visitor, java.lang.Object context)
          Calls the visitPlaceholderExpression method of the SyntaxObjectVisitor and passes that method this PlaceholderExpression and an Object.
