Functions

Link copied to clipboard
open override fun add(left: Expression<T>, right: Expression<T>): Expression<T>

Builds an Expression of addition of two another expressions.

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

Dynamically invokes a binary operation with the certain name.

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

Dynamically dispatches a binary operation with the certain name.

Link copied to clipboard
open fun bindSymbol(value: String): Expression<T>

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

Link copied to clipboard
open override fun bindSymbolOrNull(value: String): Expression<T>?

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

Link copied to clipboard
open override fun const(value: T): Expression<T>

Builds an Expression of constant expression that does not depend on arguments.

Link copied to clipboard
operator fun T.div(arg: Expression<T>): Expression<T>
operator fun Expression<T>.div(arg: T): Expression<T>

open operator fun Expression<T>.div(arg: Expression<T>): Expression<T>

Division of two elements.

open operator fun Expression<T>.div(k: Number): Expression<T>

Division of this element by scalar.

Link copied to clipboard
open override fun divide(left: Expression<T>, right: Expression<T>): Expression<T>

Builds an Expression of division an expression by another one.

Link copied to clipboard
open fun export(arg: Expression<T>): Expression<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 fun leftSideNumberOperation(operation: String, left: Number, right: Expression<T>): Expression<T>

Dynamically invokes a binary operation with the certain name with numeric first argument.

Link copied to clipboard
open fun leftSideNumberOperationFunction(operation: String): (left: Number, right: Expression<T>) -> Expression<T>

Dynamically dispatches a binary operation with the certain name with numeric first argument.

Link copied to clipboard
operator fun T.minus(arg: Expression<T>): Expression<T>
operator fun Expression<T>.minus(arg: T): Expression<T>

open operator fun Expression<T>.minus(arg: Expression<T>): Expression<T>

Subtraction of two elements.

Link copied to clipboard
open override fun multiply(left: Expression<T>, right: Expression<T>): Expression<T>

Builds an Expression of multiplication of two expressions.

Link copied to clipboard
open override fun number(value: Number): Expression<T>

Wraps a number to T object.

Link copied to clipboard
operator fun T.plus(arg: Expression<T>): Expression<T>
operator fun Expression<T>.plus(arg: T): Expression<T>

open operator fun Expression<T>.plus(arg: Expression<T>): Expression<T>

Addition of two elements.

open fun power(arg: Expression<T>, pow: Int): Expression<T>

open fun power(arg: Expression<T>, pow: UInt): Expression<T>

Raises arg to the integer power pow.

Link copied to clipboard
open fun rightSideNumberOperation(operation: String, left: Expression<T>, right: Number): Expression<T>

Dynamically invokes a binary operation with the certain name with numeric second argument.

Link copied to clipboard
open fun rightSideNumberOperationFunction(operation: String): (left: Expression<T>, right: Number) -> Expression<T>

Dynamically dispatches a binary operation with the certain name with numeric first argument.

Link copied to clipboard
open override fun scale(a: Expression<T>, value: Double): Expression<T>

open operator fun Expression<T>.times(arg: Expression<T>): Expression<T>

Multiplies this element by scalar.

open operator fun Number.times(arg: Expression<T>): Expression<T>

Multiplication of this number by element.

open operator fun Expression<T>.times(k: Number): Expression<T>

Multiplication of this element by a scalar.

Link copied to clipboard
open operator override fun Expression<T>.unaryMinus(): Expression<T>

The negation of this element.

Link copied to clipboard
