net.sf.basedb.util.overview.loader.ProtocolParameterLoader
- All Implemented Interfaces:
NodeLoader<AnnotationType>
Node loader implementation for protocol parameters. Protocol
parameters are loaded as property-type child nodes of
a protocol. The protocol must have a parent node with
an item that is
Annotatable
since this is were the
parameter values are stored.- Version:

createPropertyNode
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
