The two cache types supported areMemoryEagerGCSettings andMemoryLRUGCSettings. Custom implementation is not supported.

Declaration

protocolMemoryGarbageCollectorSettings

A type that can initialize itself from a FirestoreDocumentReference,which makes it suitable for use with the@DocumentID property wrapper.

Firestore includes extensions that makeString andDocumentReferenceconform toDocumentIDWrappable.

Note that Firestore ignores fields annotated with@DocumentID when writingso there is no requirement to convert from the wrapped type back to aDocumentReference.

publicprotocolExpression:Sendable

ABooleanExpression is anExpression that evaluates to a boolean value.

It is used to construct conditional logic within Firestore pipelines, such as inwhereclauses orConditionalExpression.BooleanExpression instances can be combined using standardlogical operators (&&,||,!,^) to create complex conditions.

Example usage in awhere clause:

firestore.pipeline().collection("products").where(Field("price").greaterThan(100)&&(Field("category").equal("electronics")||Field("on_sale").equal(true)))

Declaration

AField is aSelectable where the name is the field path.

An expression can be madeSelectable by giving it an alias using the.as() method.
