Expand description

The Tree protocol represents a hierarchy of Inspect VMOs.

Link values stored in an Inspect file contain references to new named files that contain a continuation of the data for the overall hierarchy. Protocol Tree allows clients to request these named files so long as the hosting component is still alive.

Connecting to a particular tree keeps the content for that Tree resident in memory. Clients are recommended to traverse the trees in depth-first order to reduce memory usage. Serving components are free to deny connections to avoid unbounded memory usage.

Variants§

§

GetContent

Get the content for the Inspect VMO backing this tree.

So long as the Tree connection is still maintained, the contents of the tree are guaranteed to still be live. Once the connection is lost, the serving component is free to clear the contents of returned shared buffers.

Serving components may return different buffers to GetContent requests for the same Tree.

Fields

§

ListChildNames

Iterate over the names of Trees that are children of this Tree.

The underlying list of children may change in between calls to ListChildNames and OpenChild.

Fields

§tree_iterator: ServerEnd<TreeNameIteratorMarker>
§control_handle: TreeControlHandle
§

OpenChild

Open a child Tree by name.

If the child cannot be opened, the given request is closed.

Fields

§child_name: String
§tree: ServerEnd<TreeMarker>
§control_handle: TreeControlHandle
