nroot is the superclass of all higher level NOH-dependent Nebula classes and defines this basic behavior and properties for all nroot derived classes:
- linkage into hierarchical name space of objects
- runtime type information (through nobject)
- object persistency
- language independent scripting interface
- Command Input:
v
- Command Output:
b (Success)
- Command Description:
- Save the object under its current name into a filesystem file. The filename will be 'name_of_object.n'. Such a persistent object file must be read back with the nsh 'get' command.
- Command Input:
v
- Command Output:
o (ObjectHandle)
- Command Description:
- Return the full pathname of the parent object. If the object doesn't have a parent object (this is only valid for the root object '/'), 'null' will be returned.
- Command Input:
v
- Command Output:
o (ObjectHandle)
- Command Description:
- Return full pathname of first child object, or 'null' if no child objects exist.
- Command Input:
v
- Command Output:
o (ObjectHandle)
- Command Description:
- Return full pathname of last child object, or 'null' if no child objects exist.
- Command Input:
v
- Command Output:
o (ObjectHandle)
- Command Description:
- Return full pathname of next object in the same hierarchy level, zero if no next object exists.
- Command Input:
v
- Command Output:
o (ObjectHandle)
- Command Description:
- Return full pathname of previous object in the same hierarchy level, zero if no previous object exists.
- Command Input:
v
- Command Output:
l (ListArg)
- Command Description:
- Return a list of all children.
- Command Input:
s (Name)
- Command Output:
v
- Command Description:
- Give the object a new name ('Name' may not contain any path components!).
- Command Input:
v
- Command Output:
s (Name)
- Command Description:
- Return the object's name without path.
- Command Input:
v
- Command Output:
s (Name)
- Command Description:
- Return the full pathname of the object.
- Command Input:
o (OtherObject)
- Command Output:
s (Path)
- Command Description:
- Return the shortest relative path leading from this object to the given object.
- Command Input:
s (Name)
- Command Output:
o (PathName)
- Command Description:
- Find a child object with name 'Name'. Return full path of child if found, or 'null' if not found.
- Command Input:
v
- Command Output:
v
- Command Description:
- Sort all child objects alphabetically.
- Command Input:
v
- Command Output:
i (TreeInstanceSize)
- Command Description:
- This is the recursive version of getinstancesize.
