Subtraction

object Subtraction : ArithmeticOperator

Functions

alternativeTypes

open fun alternativeTypes(): List<FunctionType>

In lieu of polymorphic types, have an optional list of alternative types to check against.

open override fun apply(arguments: List<Value>): Value

Computes the result of applying this operator to arguments.

override fun apply(argument1: Value, argument2: Value): Value

Computes the result of applying this operator to argument1 and argument2.

open override fun apply(left: Int, right: Int): Int

open override fun toDocument(arguments: List<PrettyPrintable>): Document

Shows this operator applied to arguments.

override fun toDocument(argument1: PrettyPrintable, argument2: PrettyPrintable): Document

Shows this operator applied to argument1 and argument2.

open override fun toString(): String

Properties

override val associativity: Associativity

Determines the grouping of consecutive operators that have the same precedence.

open override val precedence: Precedence

Determines the order of this operator with respect to (a subset of) other operators. Operators with higher precedence bind tighter than operators with lower precedence (for example, multiplication has higher precedence than addition).

override val type: FunctionType

The type of this operator.

Extensions

val Operator.arity: Int

The number of arguments this operator takes.

bindsTighterThan

fun Operator.bindsTighterThan(other: Operator): Boolean

Returns true when this operator has precedence higher than or equal to other.
