FunctionArgument

public final class BinaryOperatorExpression

extends RowExpression

A RowExpression that represents a binary operator and two expressions that are the operands of the expression. A BinaryOperatorExpression is like a compound expression in SQL. The binary operators specify addition, subtraction, multiplication, division, or concatenation operations.

Field Summary

static java.lang.String	CONCAT A constant that represents the || concatenation operator.
static java.lang.String	DIVIDE A constant that represents the / division operator.
static java.lang.String	MINUS A constant that represents the - subtraction binary operator.
static java.lang.String	PLUS A constant that represents the + addition binary operator.
static java.lang.String	TIMES A constant that represents the * multiplication operator.

Constructor Summary

BinaryOperatorExpression(java.lang.String operator, TypedExpression[] arguments)
Creates a BinaryOperatorExpression that represents the operation specified by the binary operator upon the arguments.

BinaryOperatorExpression(TypedExpression lhsArgument, java.lang.String operator, TypedExpression rhsArgument)
Creates a BinaryOperatorExpression that represents the operation specified by the binary operator upon the arguments.

Method Summary

TypedExpression[]	getArguments() Gets the expressions that are the arguments that are associated with this BinaryOperatorExpression.
java.lang.String	getOperator() Gets the operator that is associated with this BinaryOperatorExpression.
java.lang.Object	visit(SyntaxObjectVisitor visitor, java.lang.Object context) Calls the visitBinaryOperatorExpression method of the SyntaxObjectVisitor and passes that method this BinaryOperatorExpression and an Object.

Constructor Detail

BinaryOperatorExpression

public BinaryOperatorExpression(java.lang.String operator,
                                TypedExpression[] arguments)

Creates a BinaryOperatorExpression that represents the operation specified by the binary operator upon the arguments.

Parameters:

operator - One of the constants of this class, such as BinaryOperatorExpression.PLUS.

arguments - An array of TypedExpression objects upon which the binary operator acts.

BinaryOperatorExpression

public BinaryOperatorExpression(TypedExpression lhsArgument,
                                java.lang.String operator,
                                TypedExpression rhsArgument)

Creates a BinaryOperatorExpression that represents the operation specified by the binary operator upon the arguments.

Parameters:

lhsArgument - A TypedExpression for the left-hand argument of the operation.

operator - One of the constants of this class, such as BinaryOperatorExpression.PLUS.

rhsArgument - A TypedExpression for the right-hand argument of the operation.

Method Detail

visit
