Abstract: An apparatus and method of mapping a file name to a computer system in a network of computer systems are provided. In a first embodiment, a list of names of the computer systems starting with a root name is created. The filename itself starts with a root name and consists of an aggregation of names. When the filename is obtained, each name is matched one at a time and in the order of appearance to the names in the list. In order for a match, the order of appearance of the names in the list of names and that of the names in the filename must be the same. The last name in the list of names to be matched with a name in the filename represents a computer system within which the file is contained. In a second embodiment, the list of names is in the form of a tree of names. Matching the names of the tree to the names in the filename includes traversing a branch of that tree to a leaf node, the leaf node being the last node in the tree.

Abstract: A separate window is provided for each of multiple OpenDoc Canvas objects, thereby effecting a multiple Canvas-per-compound document design. Possibility of one OpenDoc object drawing in another object's screen area is eliminated by clipping imposed by the graphics engine on a per-window basis. Multiple different rendering libraries may be employed for screen imaging. The raw window may be used for direct platform-specific drawing functions and other rendering toolkits. User interface elements associated with alternative graphical user interfaces may be used as the root of a window hierarchy. A PlatformCanvas represents a handle to platform-dependent data types which are passed directly to native drawing routines and which provides a generic entity for specifically handling platform-specific architectures, providing a generic representation of platform-specific structures.
