BinaryExpression

class BinaryExpression

Expression representing a binary operation.

DEFINITION

class BinaryExpression;

constructor BinaryExpression

Create a binary expression.

DEFINITION

BinaryExpression	(	const Location & location,
		Expression left,
		Expression::BinaryOperation operation,
		Expression right	);

PARAMETER	DESCRIPTION
`location`	The location of the expression in the source code.
`left`	The left operand.
`operation`	The binary operation.
`right`	The right operand.

method collect_objectsconstvirtual

DEFINITION

virtual void collect_objects

(

std::unordered_set< Object * > & objects

) const;

PARAMETER	DESCRIPTION
`objects`

method createstatic

Create an expression from a binary operation.

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

DEFINITION

static Expression create	(	const Location & location,
		const Expression & left,
		Expression::BinaryOperation operation,
		const Expression & right	);

PARAMETER	DESCRIPTION
`location`	The location of the expression in the source code.
`left`	The left operand.
`operation`	The binary operation.
`right`	The right operand.

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.

method typeconstvirtual

Get the type of the expression's value if it can be determined.

DEFINITION

virtual std::optional< Value::Type > type

(

) const;

RETURNS	DESCRIPTION
`std::optional< Value::Type >`	The type of the expression's value.
