nearest

nearest( String sSubPath, ProgressMonitor mon ) → DasNode

Walk down a given sub-path as far as possible and retrieve the closest descendant FIXME: Find a better name for this function, maybe resolveDeepest

Parameters

sSubPath - A sub-path to resolve into a fully loaded node. If this node is a root catalog, then the sub-path is the complete path.
mon - A progress monitor since sub-node lookup can involve network operations

Returns:

The deepest resolvable node which may just be "this", or even the "parent" in cases where this node is a stub that can't even resolve itself.

pathSeparator

pathSeparator( ProgressMonitor mon ) → String

Get the separator string to place after my path but before then names of any child items when generating a child path string.

Parameters

mon - The separator may be defined in the object data which may trigger Phase-2 construction. Since this is a network operation a progress monitor may be supplied.

Returns:

The path separator string, which may be zero length (and that's okay).

resolve

resolve( String sSubPath, ProgressMonitor mon ) → DasNode

Walk down a given sub-path and retrieve a fully constructed descendant node.

Parameters

sSubPath - A sub-path to resolve into a fully loaded node. If this node is a root catalog, then the sub-path is the complete path.
mon - A progress monitor since sub-node lookup can involve network operations

Returns:

The full constructed child node object.
