Interface IQueryingClient

Contains functionality to query and scroll for entities.

Namespace: StylelabsStylelabs.MSdkClients

Assembly: Stylelabs.M.Sdk.dll

Syntax

public interface IQueryingClient

Methods

CreateEntityIdIterator(Query)

Creates an IEntityIterator that iterates over all ids matched by the Query.

Declaration

IIdIterator CreateEntityIdIterator(Query query)

Parameters

TypeNameDescription
QueryqueryThe query to iterate.

Returns

TypeDescription
IIdIteratorAn iterator.

CreateEntityIdScroller(Query, TimeSpan?)

Creates an IIdScroller that scrolls over all ids of entities that match the Query.

Declaration

IIdScroller CreateEntityIdScroller(Query query, TimeSpan? scrollTime = null)

Parameters

TypeNameDescription
QueryqueryThe query to scroll.
TimeSpanscrollTimeThe time for the scroll to live. If it is not specified, ScrollTime will be used. The scroll time should not be too long, just enough to process each batch of results.

Returns

TypeDescription
IIdScrollerAn IIdScroller instance.

Remarks

Use scrolling wisely and try to limit the scrollTime for the scroll to live. Using scrolling inappropriately can cause performance issues. See https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-scroll.html for more information.

CreateEntityIterator(Query, IEntityLoadConfiguration)

Creates an IEntityIterator that iterates over all results matched by the Query.

Declaration

IEntityIterator CreateEntityIterator(Query query, IEntityLoadConfiguration loadConfiguration = null)

Parameters

TypeNameDescription
QueryqueryThe query to iterate.
IEntityLoadConfigurationloadConfigurationThe load configuration. If it is null, then Default will be used.

Returns

TypeDescription
IEntityIteratorAn iterator.

Remarks

For compatibility with the 3.0 SDK, the loading configuration is resolved as follows:

  1. The loadConfiguration will be used, if not null.
  2. The IQueryLoadConfiguration from the query will be used, if not null and if applicable.
  3. Otherwise, defaults to Default.

CreateEntityScroller(Query, TimeSpan?, IEntityLoadConfiguration)

Creates an IEntityScroller that scrolls over all entities that match the Query.

Declaration

IEntityScroller CreateEntityScroller(Query query, TimeSpan? scrollTime = null, IEntityLoadConfiguration loadConfiguration = null)

Parameters

TypeNameDescription
QueryqueryThe query to scroll.
TimeSpanscrollTimeThe time for the scroll to live. If it is not specified, ScrollTime will be used. The scroll time should not be too long, just enough to process each batch of results.
IEntityLoadConfigurationloadConfigurationThe load configuration. If it is null, then Default will be used.

Returns

TypeDescription
IEntityScrollerAn IEntityScroller instance.

Remarks

Use scrolling wisely and try to limit the scrollTime for the scroll to live. Using scrolling inappropriately can cause performance issues. See https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-scroll.html for more information.

QueryAsync(Query, IEntityLoadConfiguration)

IEntityLoadConfigurationloadConfigurationThe load configuration. If it is null, then Default will be used.

Returns

TypeDescription
Task<>IEntityQueryResultAn IEntityQueryResult containing the results of the query.

Remarks

For compatibility with the 3.0 SDK, the loading configuration is resolved as follows:

  1. The loadConfiguration will be used, if not null.
  2. The IQueryLoadConfiguration from the query will be used, if not null and if applicable.
  3. Otherwise, defaults to Default.

QueryIdsAsync(Query)

Declaration

Task<IIdQueryResult> QueryIdsAsync(Query query)

Parameters

Task<IEntity> SingleAsync(Query query, IEntityLoadConfiguration loadConfiguration = null)

Parameters

TypeNameDescription
QueryqueryThe query to execute.
IEntityLoadConfigurationloadConfigurationThe load configuration. If it is null, then Default will be used.

Returns

TypeDescription
Task<>IEntityThe entity that matches the query or null if there are no results.

Remarks

For compatibility with the 3.0 SDK, the loading configuration is resolved as follows:

  1. The loadConfiguration will be used, if not null.
  2. The IQueryLoadConfiguration from the query will be used, if not null and if applicable.
