  • Method Details

    • getStoreName

      String getStoreName()
       Required. The lock store name,e.g. `redis`.
      string store_name = 1 [json_name = "storeName"];
      Returns:
      The storeName.

    • getStoreNameBytes

      com.google.protobuf.ByteString getStoreNameBytes()
       Required. The lock store name,e.g. `redis`.
      string store_name = 1 [json_name = "storeName"];
      Returns:
      The bytes for storeName.

    • getResourceId

      String getResourceId()
       Required. resource_id is the lock key. e.g. `order_id_111`
 It stands for "which resource I want to protect"
      string resource_id = 2 [json_name = "resourceId"];
      Returns:
      The resourceId.

    • getResourceIdBytes

      com.google.protobuf.ByteString getResourceIdBytes()
       Required. resource_id is the lock key. e.g. `order_id_111`
 It stands for "which resource I want to protect"
      string resource_id = 2 [json_name = "resourceId"];
      Returns:
      The bytes for resourceId.

    • getLockOwner

      String getLockOwner()
       Required. lock_owner indicate the identifier of lock owner.
 You can generate a uuid as lock_owner.For example,in golang:
 req.LockOwner = uuid.New().String()
 This field is per request,not per process,so it is different for each request,
 which aims to prevent multi-thread in the same process trying the same lock concurrently.
 The reason why we don't make it automatically generated is:
 1. If it is automatically generated,there must be a 'my_lock_owner_id' field in the response.
 This name is so weird that we think it is inappropriate to put it into the api spec
 2. If we change the field 'my_lock_owner_id' in the response to 'lock_owner',which means the current lock owner of this lock,
 we find that in some lock services users can't get the current lock owner.Actually users don't need it at all.
 3. When reentrant lock is needed,the existing lock_owner is required to identify client and check "whether this client can reenter this lock".
 So this field in the request shouldn't be removed.
      string lock_owner = 3 [json_name = "lockOwner"];
      Returns:
      The lockOwner.

      com.google.protobuf.ByteString getLockOwnerBytes()

      string lock_owner = 3 [json_name = "lockOwner"];
      Returns:
      The bytes for lockOwner.

    • getExpiryInSeconds

      int getExpiryInSeconds()
       Required. The time before expiry.The time unit is second.
      int32 expiry_in_seconds = 4 [json_name = "expiryInSeconds"];
      Returns:
      The expiryInSeconds.
