18 class GetSlivers(Method):
20 Returns an array of structs representing nodes and their slivers
21 (slices bound to nodes). If node_filter is specified, only
22 information about the specified nodes will be returned. If
23 node_filter is not specified and called by a node, only
24 information about the caller will be returned.

27 other calls, e.g. GetNodes, GetNodeNetworks, GetSlices, etc. This
28 function exists primarily for the benefit of Node Manager and
