Method for saving and retrieving print data in a network

Abstract

In a method for administration and processing of file structures in a computer network by program modules generated from an object-oriented programming language, a plurality of file administration program modules are provided respectively administering a data region. The file administration program modules respectively cooperate with a uniform interface program module that defines at least one of abstract functions and methods for at least one of administration and processing of file structures. The file administration program modules respectively comprise at least one implementation of the at least one of abstract functions and methods.

1 . A method for administration and processing of file structures in a computer network by program modules generated from an object-oriented programming language, comprising the steps of: 
 respectively administering with a plurality of file administration program modules a data region;    the file administration program modules respectively cooperating with a uniform interface program module that defines at least one of abstract functions and methods for at least one of administration and processing of file structures; and    the file administration program modules respectively comprising at least one implementation of the at least one of abstract functions and methods.    
   
   
       2 . A method according to  claim 1  wherein the file administration program modules are hierarchically connected such that respectively one superordinate file administration program module issues at least one of query commands and access commands regarding an associated data region to at least one subordinate file administration program module.  
   
   
       3 . A method according to  claim 1  wherein the uniform interface program module is respectively attached to a subordinate file administration program module such that its communication with a superordinate file administration program module occurs via the interface program module.  
   
   
       4 . A method according to  claim 1  wherein the interface program module is attached to a hierarchically uppermost file administration program module, and it is communicated with by a graphical user interface program module.  
   
   
       5 . A method according to  claim 1  wherein the uniform interface program module comprises a class in a sense of the object-oriented programming language, and whereby the implementations are respectively generated as a derivative from the uniform interface program module.  
   
   
       6 . A method according to  claim 1  wherein print data are transferred by means of a foreign connection interface provided in the interface program module from a first print server whose files are not directly administered by the interface program module to a second print server whose files are directly administered by the interface program module, and then a print device is processed on a print server whose files are directly administered by the interface program module.
