### Service "neo.fs.v2.container.ContainerService"
|
|
`ContainerService` provides API to interact with `Container` smart contract
|
|
in NeoFS sidechain via other NeoFS nodes. All of those actions can be done
|
|
equivalently by directly issuing transactions and RPC calls to sidechain
|
|
nodes.
|
|
|
|
```
|
|
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);
|
|
rpc AnnounceUsedSpace(AnnounceUsedSpaceRequest) returns (AnnounceUsedSpaceResponse);
|
|
|
|
```
|
|
|
|
#### Method Put
|
|
|
|
`Put` invokes `Container` smart contract's `Put` method and returns
|
|
response immediately. After a new block is issued in sidechain, request is
|
|
verified by Inner Ring nodes. After one more block in sidechain, container
|
|
is added into smart contract storage.
|
|
|
|
| Name | Input | Output |
|
|
| ---- | ----- | ------ |
|
|
| Put | [PutRequest](#neo.fs.v2.container.PutRequest) | [PutResponse](#neo.fs.v2.container.PutResponse) |
|
|
#### Method Delete
|
|
|
|
`Delete` invokes `Container` smart contract's `Delete` method and returns
|
|
response immediately. After a new block is issued in sidechain, request is
|
|
verified by Inner Ring nodes. After one more block in sidechain, container
|
|
is added into smart contract storage.

|
#### Method SetExtendedACL
|
|
|
|
Invokes 'SetEACL' method of 'Container` smart contract and returns response
|
|
immediately. After one more block in sidechain, Extended ACL changes are
|
|
added into smart contract storage.
|
|
|

### Message SetExtendedACLResponse.Body
|
|
`SetExtendedACLResponse` has an empty body because the operation is
|
|
asynchronous and update should be reflected in `Container` smart contract's
|
|
storage after next block is issued in sidechain.

### Message Container
|
|
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.

|
|
| version | [neo.fs.v2.refs.Version](#neo.fs.v2.refs.Version) | | Container format version. Effectively the version of API library used to create container. |
|
|
| owner_id | [neo.fs.v2.refs.OwnerID](#neo.fs.v2.refs.OwnerID) | | Identifier of the container owner |
|
|
| nonce | [bytes](#bytes) | | Nonce is a 16 byte UUIDv4, used to avoid collisions of `ContainerID`s |
|
|
| basic_acl | [uint32](#uint32) | | `BasicACL` contains access control rules for owner, system, others groups and permission bits for `BearerToken` and `Extended ACL` |
|
|
| attributes | [Container.Attribute](#neo.fs.v2.container.Container.Attribute) | repeated | Attributes represent immutable container's meta data |
|
|
| placement_policy | [neo.fs.v2.netmap.PlacementPolicy](#neo.fs.v2.netmap.PlacementPolicy) | | Placement policy for the object inside the container |
|

|
|
|
|
<a name="neo.fs.v2.container.Container.Attribute"></a>
|
|
|
|
### Message Container.Attribute
|
|
`Attribute` is a user-defined Key-Value metadata pair attached to the
|
|
container. Container attributes are immutable. They are set at container
|
|
creation and can never be added or updated.
|
|
|
|
Key name must be a container-unique valid UTF-8 string. Value can't be
|
|
empty. Containers with duplicated attribute names or attributes with empty
|
|
values will be considered invalid.
|
|
|
|
There are some "well-known" attributes affecting system behaviour:
|
|
|
|
* __NEOFS__SUBNET \
|
|
String ID of container's storage subnet. Container can be attached to
|
|
only one subnet.
|
|
|
|
And some well-known attributes used by applications only:
|
|
|
|
* Name \
|
|
Human-friendly name
|
|
* Timestamp \
|
|
User-defined local time of container creation in Unix Timestamp format
