TransformRegistry

Defined in: transform/transform-registry.ts:78

Registry for transform implementations.

Maps namespace:name keys to their TransformImpl executors. The execution engine uses this to resolve AST nodes to runnable code.

Example

const registry = new TransformRegistry()
registry.register(parseJsonImpl)

// Later, during execution:
const impl = registry.get(node.transform)
const output = await impl.execute(input)

Constructors

Constructor

new TransformRegistry(): TransformRegistry

Returns

TransformRegistry

Methods

get()

get(ast): TransformImpl

Defined in: transform/transform-registry.ts:120

Get a transform implementation by its AST specification.

Parameters

ast

TransformAst

The transform AST specification

Returns

TransformImpl

The registered implementation

Throws

Error if no implementation is registered for the transform

Example

const impl = registry.get({ kind: 'transform', namespace: 'core', name: 'parseJson' })
const result = await impl.execute(jsonString)

register()

register(impl): void

Defined in: transform/transform-registry.ts:96

Register a transform implementation.

Parameters

impl

TransformImpl

The transform implementation to register

Returns

void

Example

registry.register({
  namespace: 'mypackage',
  name: 'myTransform',
  execute(input) { return transform(input) }
})
