### Service "neo.fs.v2.container.ContainerService"
ContainerService provides API to access container smart-contract in morph chain
via NeoFS node.
2020-01-30 11:41:24 +00:00
```
rpc Put(PutRequest) returns (PutResponse);
rpc Delete(DeleteRequest) returns (DeleteResponse);
rpc Get(GetRequest) returns (GetResponse);
rpc List(ListRequest) returns (ListResponse);
rpc SetExtendedACL(SetExtendedACLRequest) returns (SetExtendedACLResponse);
rpc GetExtendedACL(GetExtendedACLRequest) returns (GetExtendedACLResponse);
2020-01-30 11:41:24 +00:00
```
#### Method Put
Put invokes 'Put' method in container smart-contract and returns
response immediately. After new block in morph chain, request is verified
by inner ring nodes. After one more block in morph chain, container
added into smart-contract storage.
2020-01-30 11:41:24 +00:00
| Name | Input | Output |
| ---- | ----- | ------ |
| Put | [PutRequest](#neo.fs.v2.container.PutRequest) | [PutResponse](#neo.fs.v2.container.PutResponse) |
2020-01-30 11:41:24 +00:00
#### Method Delete
Delete invokes 'Delete' method in container smart-contract and returns
response immediately. After new block in morph chain, request is verified
by inner ring nodes. After one more block in morph chain, container
removed from smart-contract storage.
2020-01-30 11:41:24 +00:00

2020-01-30 11:41:24 +00:00
#### Method Get
Get returns container from container smart-contract storage.
2020-01-30 11:41:24 +00:00
| Name | Input | Output |
| ---- | ----- | ------ |
| Get | [GetRequest](#neo.fs.v2.container.GetRequest) | [GetResponse](#neo.fs.v2.container.GetResponse) |
2020-01-30 11:41:24 +00:00
#### Method List
List returns all owner's containers from container smart-contract
storage.

| Name | Input | Output |
| ---- | ----- | ------ |
| List | [ListRequest](#neo.fs.v2.container.ListRequest) | [ListResponse](#neo.fs.v2.container.ListResponse) |
#### Method SetExtendedACL
SetExtendedACL invokes 'SetEACL' method in container smart-contract and
returns response immediately. After new block in morph chain,
Extended ACL added into smart-contract storage.
| Name | Input | Output |
| ---- | ----- | ------ |
| SetExtendedACL | [SetExtendedACLRequest](#neo.fs.v2.container.SetExtendedACLRequest) | [SetExtendedACLResponse](#neo.fs.v2.container.SetExtendedACLResponse) |
#### Method GetExtendedACL
GetExtendedACL returns Extended ACL table and signature from container
smart-contract storage.
| Name | Input | Output |
| ---- | ----- | ------ |
| GetExtendedACL | [GetExtendedACLRequest](#neo.fs.v2.container.GetExtendedACLRequest) | [GetExtendedACLResponse](#neo.fs.v2.container.GetExtendedACLResponse) |

Container is a structure that defines object placement behaviour. Objects
can be stored only within containers. They define placement rule, attributes
and access control information. ID of the container is a 32 byte long
SHA256 hash of stable-marshalled container message.
