- All Implemented Interfaces:
- NodeLoader<Protocol>
public class ProtocolLoader
- extends BasicItemNodeLoader<Protocol>
Node loader implementation for protocols. Protocols must be loaded as
property nodes. It can't be a root node or a forward/reverse-loading
node. The property node itself is created as a property-loading node
that loads the protocol parameters when asked to load it's children.

ProtocolLoader
public ProtocolLoader()
createPropertyNode
public Node createPropertyNode(DbControl dc,
OverviewContext context,
Node parentNode)
- Description copied from interface:
NodeLoader
- Create a property node for the given parent node. A property node is a node
that is not on the main parent-child path. It is typically a node that
can't be used a root node (for example, a protocol or software). If the
parent node can have many properties of this type the loader can decide if
it should first create a folder-type node and put the children inside the
folder, or if all child nodes should be created directly in the
parent node. In the first case, the folder node should be returned. In
the latter case, null should be returned.
The direction of the node(s) should usually be ChildNodeDirection.NONE
, but
it may also be ChildNodeDirection.PROPERTY
in case the property has sub-properties.
One example is the ProtocolLoader
which loads the
protocol parameters as child nodes.
In case there is an error (permission denied, etc.) ChildNodeDirection.NONE
should be used. If there is no property item null
should be returned (but this may also indicate that more than one node
was created).
Errors, missing items, etc. should be reported as failures to the OverviewContext
.
