Class: JsonTranslator<TRoot, TShape>

Defined in: core/src/plugins/translators/JsonTranslator.ts:11

Extends

• DataTranslator<TRoot, TShape>

Type Parameters

TRoot

TRoot extends object

TShape

TShape

Constructors

Constructor

new JsonTranslator<TRoot, TShape>(query, innerSide?): JsonTranslator<TRoot, TShape>

Defined in: core/src/plugins/translators/JsonTranslator.ts:20

Parameters

query

IQuery<TRoot, TShape>

innerSide?

JoinInnerSide

The inner collection's rows, when this query carries a join option. A plugin that omits it for a query that HAS a join gets a throw from join() rather than a silently un-joined result.

Returns

JsonTranslator<TRoot, TShape>

Overrides

DataTranslator.constructor

Methods

translate()

translate(data): ITranslatedValue<TShape>

Defined in: core/src/plugins/translators/DataTranslator.ts:75

Parameters

data

unknown

Returns

ITranslatedValue<TShape>

Inherited from

DataTranslator.translate

join()

join<TResult>(data, option): TResult

Defined in: core/src/plugins/translators/JsonTranslator.ts:33

The hash join itself, over rows already in memory — the floor every non-SQL backend stands on.

Both halves are deserialized here, each with its own schema, because that is where the === on key values is specified to happen: in entity shape, by the property names the caller wrote in the key selectors. A from-renamed column reads correctly for free.

nearest()

nearest<TResult>(data, option): TResult

Defined in: core/src/plugins/translators/JsonTranslator.ts:236

The similarity search itself, over values already in memory.

This is the floor the whole feature stands on: it is reached whenever the backend did not do the search, which is every backend except the ones with a native vector index. It reads the property through the option's selector, so it works on any shape the rows arrive in.
