Method Detail
-
getChildren
Node[] getChildren()
Returns the array of child nodes belonging to this branch. All the returned values represent file objects which actuallly exist in the filesystem.- Returns:
- child nodes of this one
-
createNode
Node createNode(java.lang.String name)
Attempts to construct a new node in the context of this one. The new item may represent a new or an existing node in the filesystem. This call should not in itself perform any write operations on the filesystem (such as creating a node which doesn't currently exist), though a subsequentLeaf.getOutputStream()
call may do so.The returned node will typically be a child of this branch, but need not be, for instance if name is interpreted as an absolute path.
If the named node cannot be created, null may be returned.
- Parameters:
name
- name of a node in the context of this branch- Returns:
- node representing the location of an existing or new node
