### constructor

<MemberInfo kind="method" type={`(connection: <a href='/reference/typescript-api/data-access/transactional-connection#transactionalconnection'>TransactionalConnection</a>, configService: ConfigService, globalSettingsService: <a href='/reference/typescript-api/services/global-settings-service#globalsettingsservice'>GlobalSettingsService</a>, customFieldRelationService: CustomFieldRelationService, eventBus: <a href='/reference/typescript-api/events/event-bus#eventbus'>EventBus</a>, listQueryBuilder: <a href='/reference/typescript-api/data-access/list-query-builder#listquerybuilder'>ListQueryBuilder</a>) => ChannelService`}   />


### assignToCurrentChannel

<MemberInfo kind="method" type={`(entity: T, ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>) => Promise&#60;T&#62;`}   />

Assigns a ChannelAware entity to the default Channel as well as any channel
specified in the RequestContext. This method will not save the entity to the database, but
assigns the `channels` property of the entity.
### assignToChannels

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, entityType: Type&#60;T&#62;, entityId: <a href='/reference/typescript-api/common/id#id'>ID</a>, channelIds: <a href='/reference/typescript-api/common/id#id'>ID</a>[]) => Promise&#60;T&#62;`}   />

Assigns the entity to the given Channels and saves all changes to the database.
### removeFromChannels

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, entityType: Type&#60;T&#62;, entityId: <a href='/reference/typescript-api/common/id#id'>ID</a>, channelIds: <a href='/reference/typescript-api/common/id#id'>ID</a>[]) => Promise&#60;T | undefined&#62;`}   />

Removes the entity from the given Channels and saves.
### getChannelFromToken

<MemberInfo kind="method" type={`(token: string) => Promise&#60;<a href='/reference/typescript-api/entities/channel#channel'>Channel</a>&#62;`}   />
