MinMaxExpression

class MinMaxExpression

Expression representing the minimum or maximum of two sub-expressions: .min(a, b) or .max(a, b).

DEFINITION

class MinMaxExpression;

constructor MinMaxExpression

Create a minimum or maximum expression.

DEFINITION

MinMaxExpression	(	const Location & location,
		Expression a,
		Expression b,
		bool minimum	);

PARAMETER	DESCRIPTION
`location`	The location of the expression in the source code.
`a`	The first sub-expression.
`b`	The second sub-expression.
`minimum`	Whether this is a minimum expression (`true`) or a maximum expression (`false`).

method createstatic

Create an expression representing the minimum or maximum of two sub-expressions.

This might not create a MinMaxExpression if the operation can be simplified (e.g. if both operands have values).

DEFINITION

static Expression create	(	const Location & location,
		const Expression & a,
		const Expression & b,
		bool minimum	);

PARAMETER	DESCRIPTION
`location`	The location of the expression in the source code.
`a`	The first sub-expression.
`b`	The second sub-expression.
`minimum`	Whether this is a minimum expression (`true`) or a maximum expression (`false`).

RETURNS	DESCRIPTION
`Expression`	The created expression.

method create_maxstatic

Create a maximum expression from arguments.

DEFINITION

static Expression create_max	(	const Location & location,
		const std::vector< Expression > & arguments	);

PARAMETER	DESCRIPTION
`location`	The location of the expression in the source code.
`arguments`	The arguments of the expression. Must contain exactly two expressions.

RETURNS	DESCRIPTION
`Expression`	The created expression.

method create_minstatic

Create a minimum expression from arguments.

DEFINITION

static Expression create_min	(	const Location & location,
		const std::vector< Expression > & arguments	);

PARAMETER	DESCRIPTION
`location`	The location of the expression in the source code.
`arguments`	The arguments of the expression. Must contain exactly two expressions.

RETURNS	DESCRIPTION
`Expression`	The created expression.

method evaluatedconstvirtual

DEFINITION

virtual std::optional< Expression > evaluated

(

const EvaluationContext & context

) const;

PARAMETER	DESCRIPTION
`context`

RETURNS	DESCRIPTION
`std::optional< Expression >`

method maximum_valueconstvirtual

Get the maximum possible value of the expression if it can be determined.

DEFINITION

virtual std::optional< Value > maximum_value

(

) const;

RETURNS	DESCRIPTION
`std::optional< Value >`	The maximum possible value of the expression.

method minimum_valueconstvirtual

Get the minimum possible value of the expression if it can be determined.

DEFINITION

virtual std::optional< Value > minimum_value

(

) const;

RETURNS	DESCRIPTION
`std::optional< Value >`	The minimum possible value of the expression.

method serialize_subconstvirtual

Serialize the expression to a stream.

This method must be implemented by derived classes.

DEFINITION

virtual void serialize_sub

(

std::ostream & stream

) const;

PARAMETER	DESCRIPTION
`stream`	The stream to serialize to.
