All Implemented Interfaces:

FunctionArgument

public final class UnaryOperatorExpression
extends RowExpression

A RowExpression that represents a unary operator and an operand.

Field Summary

static java.lang.String

MINUS A constant that represents a negation operation.

Constructor Summary

UnaryOperatorExpression(java.lang.String operator, TypedExpression baseExpression)
Creates a UnaryOperatorExpression that represents the operation specified by the unary operator upon the base expression.

Method Summary

TypedExpression	getBaseExpression() Gets the base expression of this UnaryOperatorExpression.
java.lang.String	getOperator() Gets the operator that is associated with this UnaryOperatorExpression.
java.lang.Object	visit(SyntaxObjectVisitor visitor, java.lang.Object context) Calls the visitUnaryOperatorExpression method of the SyntaxObjectVisitor and passes that method this UnaryOperatorExpression and an Object.
