Methods

getChildExpressions

getChildExpressions(parentId: string | null): TExpr[]
Returns the child expressions of the given parent, sorted by position.
Parameters
- parentId: string | null
  The parent expression ID, or null for root-level children.
Returns TExpr[]
An array of child expression entities.
- Defined in src/lib/core/interfaces/premise-engine.interfaces.ts:319

getDecidableOperatorExpressions

getDecidableOperatorExpressions(): TExpr[]
Returns the operator expressions a reviewer can accept or reject, in pre-order depth-first tree order.

Excludes "not" operators (NOT is flipped via a render-time flag, not voted on) and skips formula nodes (they are traversed but never emitted). Returns [] for empty premises and premises with no operators.

Order is stable across calls on the same PremiseEngine instance; callers typically rely on index for step-queue construction.

Returns TExpr[]
An array of decidable operator expression entities.
- Defined in src/lib/core/interfaces/premise-engine.interfaces.ts:334

getExpression

getExpression(id: string): TExpr | undefined
Returns an expression by ID, or undefined if not found in this premise.
Parameters
- id: string
  The expression ID to look up.
Returns TExpr | undefined
The expression entity, or undefined.
- Defined in src/lib/core/interfaces/premise-engine.interfaces.ts:291

getExpressions

getExpressions(): TExpr[]
Returns all expressions in this premise.

Returns TExpr[]
An array of expression entities.
- Defined in src/lib/core/interfaces/premise-engine.interfaces.ts:310

getRootExpression

getRootExpression(): TExpr | undefined
Returns the root expression, or undefined if the premise is empty.

Returns TExpr | undefined
The root expression entity, or undefined.
- Defined in src/lib/core/interfaces/premise-engine.interfaces.ts:304

getRootExpressionId

getRootExpressionId(): string | undefined
Returns the ID of the root expression, or undefined if the premise is empty.

Returns string | undefined
The root expression ID, or undefined.
- Defined in src/lib/core/interfaces/premise-engine.interfaces.ts:298
