Methods

evaluate

evaluate(exp: ExpressionInput, ctx: Context): boolean

- Defined in index.ts:70
Evaluate the expression.

Parameters
- exp: ExpressionInput
  
  Raw expression.
- ctx: Context
  
  Evaluation data context.
Returns boolean

parse

parse(exp: ExpressionInput): Evaluable

- Defined in index.ts:88
Parse expression.

Parameters
- exp: ExpressionInput
  
  Raw expression.
Returns Evaluable

simplify

simplify(exp: ExpressionInput, context: Context, strictKeys?: string[], optionalKeys?: string[]): Input

- Defined in index.ts:107
Simplifies an expression with values in context.

This method tries to evaluate all the expressions and reduce them to its corresponding boolean value. If a value required for the expression is not present in the context, the minimal corresponding expression will be returned.

Parameters
- exp: ExpressionInput
  
  Raw expression.
- context: Context
  
  Evaluation data context.
- Optional strictKeys: string[]
  
  keys to be considered present even if they are not present in the context
- Optional optionalKeys: string[]
  
  keys to be considered not present unless they are in the context or in strictKeys; when strictKeys is undefined and optionalKeys is an array, every key that is not in optionalKeys is considered to be present and thus will be evaluated
Returns Input

statement

statement(exp: ExpressionInput): string

- Defined in index.ts:79
Get expression statement

Parameters
- exp: ExpressionInput
  
  Raw expression.
Returns string
