Detailed Description

This class can be used to represent binary operation expressions.

The BinaryOperator class can be used to encode the fundamental arithmetic operations of addition, subtraction, multiplication and division. Arithmetic operators are binary operators meaning that they accept two arguments and evaluate to a single result.
The following operators are defined in the Filter Encoding specification:

• Add
• Sub
• Mul
• Div

Of course, you can extend the list of supported binary operators.

Constructor & Destructor Documentation

BinaryOperator() [1/2]

te::fe::BinaryOperator::BinaryOperator

(

const char *

opName = 0

)

It initializes a new BinaryOperator.

Parameters

opName

The operator name.

Note

The BinaryOperator will not take the ownership of the given name.

BinaryOperator() [2/2]

te::fe::BinaryOperator::BinaryOperator	(	const char *	opName,
		Expression *	first,
		Expression *	second
	)

It initializes a new BinaryOperator.

Parameters

opName	The operator name.
first	The first operand.
second	The second operand.

Note

The BinaryOperator will not take the ownership of the given name.

It will take the ownership of the first and second operands.

~BinaryOperator()

virtual te::fe::BinaryOperator::~BinaryOperator ( )

virtual

Virtual destructor.
