NodeLoader<Tag>
public class TagLoader extends BasicItemNodeLoader<Tag>
Node loader implementation for tags. Tag nodes are loaded as end-point property nodes with no children. It can't be a root node or a forward/reverse-loading node.Validations:
- Incorrect tag type:
Validator.INCORRECT_TAGTYPE

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 beChildNodeDirection.PROPERTY
in case the property has sub-properties. One example is theProtocolLoader
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
