Constructors

constructor

new Logic(
    _undef?: number,
    _false?: number,
    _never?: number,
    _maybe?: number,
    _true?: number,
): Logic
Basic constructor. See fromCategory, fromArray and fromValues for more convenient instantiation methods.
Parameters
- Optional_undef: number
- Optional_false: number
- Optional_never: number
- Optional_maybe: number
- Optional_true: number
Returns Logic
- Defined in Logic.ts:44

Methods

add

add(value?: Logic): Logic
Adds value to current value (category by category). Useful for accumulation of fuzzy sums (usually with normalization in the end). Mutates the current object.
Parameters
- Optionalvalue: Logic
Returns Logic
Mutated this object.
- Defined in Logic.ts:304

and

and(value?: Logic): Logic
Fuzzy Common Sense Logical AND. See README for details.
Parameters
- Optionalvalue: Logic
Returns Logic
- Defined in Logic.ts:213

asArray

asArray(): number[]
Retrieves an array of Fuzzy values.

Returns number[]
The categories order in array is: Category.UNDEF, Category.FALSE, Category.NEVER, Category.MAYBE, Category.TRUE.
- Defined in Logic.ts:89

asCategory

asCategory(): Category | undefined
Dominating Category or undefined if none of the categories has a value greater than Fuzzy.FUZZY_FALSE.

Returns Category | undefined
- Defined in Logic.ts:103

asValues

asValues(): LogicValues
Retrieves a copy of LogicValues.

Returns LogicValues
A clone, a new instance of LogicValues created from the values kept internally.
- Defined in Logic.ts:116

clone

clone(): Logic
Creates a deep copy (a clone) of a current instance.

Returns Logic
- Defined in Logic.ts:127

eq

eq(category: Category): boolean
Returns true if category is the dominating category of this object.
Parameters
- category: Category
Returns boolean
- Defined in Logic.ts:333

get

get(category: Category): number
Returns Fuzzy value of the specified category of this Logic object.
Parameters
- category: Category
Returns number
- Defined in Logic.ts:151

getNormalized

getNormalized(category: Category): number
Returns normalized Fuzzy value for the specified category. See normalize for details.
Parameters
- category: Category
Returns number
- Defined in Logic.ts:168

isValid

isValid(): boolean
Checks that at least one of the categories has non-zero Fuzzy value.

Returns boolean
- Defined in Logic.ts:188

ne

ne(category: Category): boolean
Returns true if category is not the dominating category of this object.
Parameters
- category: Category
Returns boolean
- Defined in Logic.ts:346

normalize

normalize(): Logic
If original values are not normalized, returns new Logic object with normalized Logic value, otherwise return the same object.

The Logic value is normalized if and only if the sum of Fuzzy values of all categories equals to 1.0 (or 0.0 if there are no categories with Fuzzy value greater than Fuzzy.FUZZY_FALSE).

Returns Logic
- Defined in Logic.ts:180

not

not(): Logic
Fuzzy Common Sense Logical NOT. See README for details.

Returns Logic
- Defined in Logic.ts:195

or

or(value?: Logic): Logic
Fuzzy Common Sense Logical OR. See README for details.
Parameters
- Optionalvalue: Logic
Returns Logic
- Defined in Logic.ts:257

toString

toString(): string
String representation of five-dimensional vector of Fuzzy values. The categories order is: Category.UNDEF, Category.FALSE, Category.NEVER, Category.MAYBE, Category.TRUE.

Returns string
- Defined in Logic.ts:142

`Static`fromArray

fromArray(fuzzy: number[]): Logic
Creates new Logic instance from array of Fuzzy values.
Parameters
- fuzzy: number[]
  The categories order in array is: Category.UNDEF, Category.FALSE, Category.NEVER, Category.MAYBE, Category.TRUE.
Returns Logic
- Defined in Logic.ts:73

`Static`fromCategory

fromCategory(category: Category): Logic
Creates new Logic instance with Fuzzy.FUZZY_TRUE value for the specified category (and Fuzzy.FUZZY_FALSE for all other categories).
Parameters
- category: Category
Returns Logic
- Defined in Logic.ts:58

`Static`fromValues

fromValues(fuzzy: LogicValues): Logic
Creates new Logic instance from LogicValues.
Parameters
- fuzzy: LogicValues
Returns Logic
- Defined in Logic.ts:80
