Functions

abstract fun add(left: T, right: T): T

Addition of two elements.

open fun binaryOperation(operation: String, left: T, right: T): T

Dynamically invokes a binary operation with the certain name.

Link copied to clipboard
open override fun binaryOperationFunction(operation: String): (left: T, right: T) -> T

Dynamically dispatches a binary operation with the certain name.

open fun bindSymbol(value: String): T

The same as bindSymbolOrNull but throws an error if symbol could not be bound

fun <T> Algebra<T>.bindSymbol(symbol: Symbol): T
Link copied to clipboard
open fun bindSymbolOrNull(value: String): T?

Wraps a raw string to T object. This method is designed for three purposes:

fun <T> Algebra<T>.bindSymbolOrNull(symbol: Symbol): T?

open fun export(arg: T): T

Export an algebra element, so it could be accessed even after algebra scope is closed. This method must be used on algebras where data is stored externally or any local algebra state is used. By default (if not overridden), exports the object itself.

open operator fun T.minus(arg: T): T

Subtraction of two elements.

Link copied to clipboard
open operator fun T.plus(arg: T): T

Addition of two elements.

Link copied to clipboard
abstract operator fun T.unaryMinus(): T

The negation of this element.

open fun unaryOperation(operation: String, arg: T): T

Dynamically invokes a unary operation with the certain name.

Link copied to clipboard
open override fun unaryOperationFunction(operation: String): (arg: T) -> T

Dynamically dispatches a unary operation with the certain name.

Link copied to clipboard
open operator fun T.unaryPlus(): T

Returns this value.
