FunctionalExpressionAlgebra

abstract class FunctionalExpressionAlgebra<T, out A : Algebra<T>>(val algebra: A) : ExpressionAlgebra<T, Expression<T>> (source)

A context class for Expression construction.

Parameters

algebra

The algebra to provide for Expressions built.

Inheritors

FunctionalExpressionGroup

Constructors

FunctionalExpressionAlgebra

constructor(algebra: A)

Functions

binaryOperation

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

Dynamically invokes a binary operation with the certain name.

binaryOperationFunction

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

Dynamically dispatches a binary operation with the certain name.

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

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

fun <T> Algebra<T>.bindSymbol(symbol: Symbol): T

bindSymbolOrNull

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

Builds an Expression to access a variable.

bindSymbolOrNull

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

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

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

@UnstableKMathAPI

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 unaryOperation(operation: String, arg: Expression<T>): Expression<T>

Dynamically invokes a unary operation with the certain name.

unaryOperationFunction

open override fun unaryOperationFunction(operation: String): (arg: Expression<T>) -> Expression<T>

Dynamically dispatches a unary operation with the certain name.

Properties

val <T, E> ExpressionAlgebra<T, E>.binding: ReadOnlyProperty<Any?, E>

Bind a symbol by name inside the ExpressionAlgebra

open val bufferFactory: MutableBufferFactory<Expression<T>>

Provide a factory for buffers, associated with this Algebra
