```

type ObjectAPI interface {
// Bucket resource API.

ListBuckets() ([]BucketInfo, *probe.Error)

GetBucketInfo(bucket string) (BucketInfo, *probe.Error)
// Bucket query API.

ListMultipartUploads(bucket string, resources BucketMultipartResourcesMetadata) (BucketMultipartResourcesMetadata, *probe.Error)
// Object resource API.
