### findAll
\
RequestContext, options?: ListQueryOptions<ProductOptionGroup>, relations?: RelationPaths<ProductOptionGroup>) => Promise<PaginatedListProductOptionGroup>>>`} />
### findOne

### getOptionGroupsByProductId
\RequestContext, id: ID) => PromiseProductOptionGroup>>>`} />
### getOptionGroupChannels
\RequestContext, optionGroupId: ID) => Promise<Channel[]>`} />
Returns all Channels to which the ProductOptionGroup is assigned.
### getProductCount
\RequestContext, optionGroupId: ID) => Promise`} />
Returns the number of non-deleted Products in the current channel
that use the given ProductOptionGroup.
### create

### update
\RequestContext, input: UpdateProductOptionGroupInput) => PromiseProductOptionGroup>>`} />
### delete
\RequestContext, id: ID, force: boolean = false) => Promise`} />
Deletes a ProductOptionGroup. If the group is in use by any Products, the deletion
will fail unless `force` is set to `true`.
### deleteGroupAndOptionsFromProduct
\RequestContext, id: ID, productId: ID) => `} />
Deletes the ProductOptionGroup and any associated ProductOptions. If the ProductOptionGroup
is still referenced by a soft-deleted Product, then a soft-delete will be used to preserve
referential integrity. Otherwise a hard-delete will be performed.
### assignProductOptionGroupsToChannel
\RequestContext, input: AssignProductOptionGroupsToChannelInput) => PromiseProductOptionGroup>>>`} />
Assigns ProductOptionGroups to the specified Channel
### removeProductOptionGroupsFromChannel
\RequestContext, input: RemoveProductOptionGroupsFromChannelInput) => Promise< Array<ErrorResultUnionProductOptionGroup>>> >`} />
Removes ProductOptionGroups from the specified Channel
