DYNAMIC ASSIGNING METHOD FOR TYPE INFORMATION IN DATA STRUCTURE DEFINITION USING ABSTRACT SYNTAX DESCRIPTION METHOD

摘要

PROBLEM TO BE SOLVED: To dynamically assign type information by applying data structure definition described according to an ASN.1 specification at the time of executing a program described in an object-oriented language at the time of executing the operation of a data structure based on the data structure definition by the program.;SOLUTION: A function jump table 5 is prepared for each basic classification of an ASN.1 type, and a dictionary item instance 2 is prepared for a type which can be referred to by the other without necessitating the inner modification of a type based on the data structure definition and the integrated type of the ASN.1, and a dictionary instance 1 for holding the dictionary item instances is prepared. At the time of operating the data structure, the pointer of the dictionary item instance 2 is set at a value handle instance 4 so that the type information can be assigned, and processing corresponding to the type can be called by referring to the function jump table 5.;COPYRIGHT: (C)2000,JPO
