public class HardwareLoader
Node loader implementation for hardware. Hardware is loaded as end-point property nodes with no children. It can't be a root node or a forward/reverse-loading node.
Validations:
Validator.MISSING_HARDWARE
Validator.DENIED_HARDWARE
Validator.INCORRECT_HARDWARETYPE
Validator.NONDEFAULT_HARDWARE

public Node createPropertyNode(DbControl dc, OverviewContext context, Node parentNode)
NodeLoader
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
.
