BooleanExpression

sealed class BooleanExpression<out T : Any>

A boolean expression

Parameters

the type of the variable elements. This allows representing BooleanExpression that only contain variables and other that may also contain possibleTypes

Types

And

data class And<T : Any>(val operands: Set<BooleanExpression<T>>) : BooleanExpression<T>

Element

data class Element<out T : Any>(val value: T) : BooleanExpression<T>

False

object False : BooleanExpression<Nothing>

Not

data class Not<out T : Any>(val operand: BooleanExpression<T>) : BooleanExpression<T>

data class Or<T : Any>(val operands: Set<BooleanExpression<T>>) : BooleanExpression<T>

True

object True : BooleanExpression<Nothing>

Functions

simplify

abstract fun simplify(): BooleanExpression<T>

This is not super well defined but works well enough for our simple use cases
