All Implemented Interfaces:

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.
