FunctionalExpressionGroup

open class FunctionalExpressionGroup<T, out A : Group<T>>(algebra: A) : FunctionalExpressionAlgebra<T, A> , Group<Expression<T>>

A context class for Expression construction for Ring algebras.

Constructors

common

Functions

add

common

open override fun add(a: Expression<T>, b: Expression<T>): Expression<T>

Builds an Expression of addition of two another expressions.

binaryOperation

common

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

Dynamically invokes a binary operation with the certain name.

binaryOperationFunction

common

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

Dynamically dispatches a binary operation with the certain name.

bindSymbol

common

open fun bindSymbol(value: String): Expression<T>

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

common

open override fun bindSymbolOrNull(value: String): Expression<T>?

Builds an Expression to access a variable.

const

common

open override fun const(value: T): Expression<T>

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

minus

common

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