interface ConditionCapable<Q : ConditionCapable<Q>> : RewritableCondition<Q>

DeletionState

enum DeletionState : Enum<DeletionState>

DynamicDocument

interface DynamicDocument : MutableMap<String, Any>

ICondition

interface ICondition<C : ICondition<C>>

IListQuery

interface IListQuery : Queryable<IListQuery>

IMaterializedSnapshot

interface IMaterializedSnapshot<S : Any> : Materialized, StateCapable<S>

IPagedList

interface IPagedList<out T>

interface IPagedQuery : Queryable<IPagedQuery>

ISingleQuery

interface ISingleQuery : Queryable<ISingleQuery>

ListQuery

data class ListQuery(val condition: Condition, val projection: Projection = Projection.ALL, val sort: List<Sort> = emptyList(), val limit: Int = Pagination.DEFAULT.size) : IListQuery

MaterializedSnapshot

data class MaterializedSnapshot<S : Any>(val contextName: String, val aggregateName: String, val tenantId: String, val ownerId: String = OwnerId.DEFAULT_OWNER_ID, val aggregateId: String, val version: Int, val eventId: String, val firstOperator: String, val operator: String, val firstEventTime: Long, val eventTime: Long, val state: S, val snapshotTime: Long, val deleted: Boolean) : IMaterializedSnapshot<S> , NamedAggregate, TenantId, OwnerId, Version, EventIdCapable, FirstOperatorCapable, OperatorCapable, FirstEventTimeCapable, EventTimeCapable, SnapshotTimeCapable, DeletedCapable

MediumMaterializedSnapshot

data class MediumMaterializedSnapshot<S : Any>(val tenantId: String, val ownerId: String, val version: Int, val eventId: String, val firstOperator: String, val operator: String, val firstEventTime: Long, val eventTime: Long, val state: S) : IMaterializedSnapshot<S> , TenantId, OwnerId, Version, EventIdCapable, FirstOperatorCapable, OperatorCapable, FirstEventTimeCapable, EventTimeCapable

Represents a materialized snapshot for medium data, implementing multiple capabilities through inheritance. This class is designed to be generic, capable of holding state data of any type. Each snapshot corresponds to a specific version of the state within a tenant and owner context, and records information such as event IDs and operation times to support tracing and auditing.

Operator

enum Operator : Enum<Operator>

PagedList

data class PagedList<out T>(val total: Long, val list: List<T>) : IPagedList<T>

PagedQuery

data class PagedQuery(val condition: Condition, val projection: Projection = Projection.ALL, val sort: List<Sort> = emptyList(), val pagination: Pagination = Pagination.DEFAULT) : IPagedQuery

Pagination

data class Pagination(val index: Int, val size: Int)

Projection

data class Projection(val include: List<String> = emptyList(), val exclude: List<String> = emptyList())

ProjectionCapable

interface ProjectionCapable<Q : RewritableProjection<Q>> : RewritableProjection<Q>

Queryable

interface Queryable<Q : Queryable<Q>> : ConditionCapable<Q> , ProjectionCapable<Q> , SortCapable

RewritableCondition

interface RewritableCondition<Q : RewritableCondition<Q>>

RewritableProjection

interface RewritableProjection<Q : RewritableProjection<Q>>

SimpleDynamicDocument

class SimpleDynamicDocument(val delegation: MutableMap<String, Any>) : DynamicDocument, MutableMap<String, Any>

SingleQuery

data class SingleQuery(val condition: Condition, val projection: Projection = Projection.ALL, val sort: List<Sort> = emptyList()) : ISingleQuery

SmallMaterializedSnapshot

data class SmallMaterializedSnapshot<S : Any>(val version: Int, val firstEventTime: Long, val state: S) : Version, FirstEventTimeCapable, IMaterializedSnapshot<S>

Represents a simplified materialized snapshot with generic state. This data class implements multiple interfaces to provide version, materialization, first event time, and state information.

Sort

data class Sort(val field: String, val direction: Sort.Direction)

SortCapable

interface SortCapable

Functions

isEmpty

fun Projection.isEmpty(): Boolean

toMedium

fun <S : Any, D : Any> MaterializedSnapshot<S>.toMedium(materialize: (S) -> D): MediumMaterializedSnapshot<D>

toSmall

fun <S : Any, D : Any> MaterializedSnapshot<S>.toSmall(materialize: (S) -> D): SmallMaterializedSnapshot<D>

Converts a materialized snapshot into a simplified snapshot form. This function is used to transform a full snapshot into a simplified snapshot with transformed state.
