### assignToCurrentChannel \RequestContext) => Promise`} /> 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 \RequestContext, entityType: Type, entityId: ID, channelIds: ID[]) => Promise`} /> Assigns the entity to the given Channels and saves all changes to the database. ### removeFromChannels \RequestContext, entityType: Type, entityId: ID, channelIds: ID[]) => Promise`} /> Removes the entity from the given Channels and saves. ### getChannelFromToken \ Promise<Channel>`} /> Given a channel token, returns the corresponding Channel if it exists, else will throw a [ChannelNotFoundError](/current/core/reference/typescript-api/errors/error-types#channelnotfounderror). ### getChannelFromToken \RequestContext, token: string) => Promise<Channel>`} /> ### getChannelFromToken \RequestContext | string, token?: string) => Promise<Channel>`} /> ### getDefaultChannel \RequestContext) => Promise<Channel>`} /> Returns the default Channel. ### findAll \RequestContext, options?: ListQueryOptions<Channel>, relations?: RelationPaths<Channel>) => Promise<PaginatedList<Channel>>`} /> ### findOne \RequestContext, id: ID) => Promise<Channel | undefined>`} /> ### create \RequestContext, input: CreateChannelInput) => Promise<ErrorResultUnionChannel>>`} /> ### update \RequestContext, input: UpdateChannelInput) => Promise<ErrorResultUnionChannel>>`} /> ### delete \RequestContext, id: ID) => Promise`} /> ### isChannelAware \VendureEntity) => entity is VendureEntity & ChannelAware`} /> Type guard method which returns true if the given entity is an instance of a class which implements the [ChannelAware](/current/core/reference/typescript-api/entities/interfaces#channelaware) interface.
