	VariablesEquality (Variable lhs, Variable rhs)
	operator bool () const

Public Attributes
Variable	lhs
Variable	rhs

Detailed Description

The result of the equality comparison between two Variable.

We use an object here to delay the evaluation of equality so that we can use the operator== in two use-cases:

1. when the user want to test that two Variable values references the same variable. This is supported by having this object support implicit conversion to bool.
2. when the user want to use the equality to create a constraint of equality between two variables.

Constructor & Destructor Documentation

VariablesEquality()

operations_research::math_opt::internal::VariablesEquality::VariablesEquality ( Variable lhs, Variable rhs )

inline

Users are not expected to call this constructor. Instead they should only use the overload of operator== that returns this when comparing two Variable. For example x == y.
