QuerySpec class

A compiled collection query, ready for a CrdtTable to execute: the conjunction of predicates, an optional order, and a keyset page window.

Constructors

QuerySpec({required List<QueryPredicate> predicates, String? orderByPath, CrdtType orderByType = const LwwRegister(), bool descending = false, int? limit, QueryCursor? after})

Creates a spec. Built by CollectionQuery; validation happens there.

const

Properties

after → QueryCursor?

Resume after this position (exclusive) in the query's total order: keyset pagination. null starts from the beginning.

final

descending → bool

Whether the order is reversed. The document-id tiebreak reverses with it, so pages stay disjoint in either direction.

final

hashCode → int

The hash code for this object.

no setter, inherited

limit → int?

The maximum number of documents to return, or null for all.

final

orderByPath → String?

The field path to order by, or null to order by document id alone. Documents that lack the field sort together, before every non-null value (after them when descending).

final

orderByType → CrdtType

The CrdtType of the field at orderByPath.

final

predicates → List<QueryPredicate>

The where clauses, combined with AND.

final

runtimeType → Type

A representation of the runtime type of the object.

Methods

noSuchMethod(Invocation invocation) → dynamic

inherited

A string representation of this object.
