Detailed Description

Factory class to help build ExpressionAdd expressions.

Note: Once GetExpression() is called and an expression is generated, this class should not be used again. If another GetExpression() is called, it will throws an exception.

Member Function Documentation

ExpressionAddFactory & dlinear::drake::symbolic::ExpressionAddFactory::Negate ( )

Negates the expressions in factory.

If it represents c0 + c1 * t1 + ... + * cn * tn, this method flips it into -c0 - c1 * t1 - ... - cn * tn.

ExpressionAddFactory & dlinear::drake::symbolic::ExpressionAddFactory::operator= ( const ExpressionAdd * ptr )

Assigns a factory from a pointer to ExpressionAdd.
