Method for performing data structure conversions

A utility for performing data structure conversions in a communications system, wherein at least one data structure comprises at least two elements located in a predetermined order in the data structure elements located in a predetermined order in the data structure which is defined for communication by a definition language and represented in the communication as bit strings, the utility being adapted to convert a source bit string conforming to a first format into a target bit string conforming to a second format,

• characterized in that the utility comprises:
• means for browsing the source bit string,
• means for identifying a first data structure element in the source bit string,
• means for handling identified data structure elements in the same order as they are located in the data structure without parsing the source bit string, said means for the handling being adapted to decode each data structure element from the source bit string and encode the decoded data structure element directly into the target bit string.

A compiler for creating utilities for a utility set by using at least two class libraries containing classes and a certain definition file containing definitions, the utilities being adapted to perform data structure conversions in a communications system, wherein at least one data structure comprises at least two elements located in a predetermined order in the data structure, which is defined for communication by a definition language and represented in the communication as bit strings,

• characterized in that the compiler comprises:
• means for reading a definition from the definition file and writing it into a memory,
• means for parsing the writing definition, whereby a parsed class name is obtained as a result of the parsing,
• means for reading a first class corresponding to the parsed class name from the first class library and writing the first class into the memory,
• means for reading a second class corresponding to the parsed class name from the second class library and writing the second class into the memory,
• means for generating at least one wrapper class, which is adapted to call at least one method of the first class and at least one method of the second class, wherein said methods handle data of the same context,
• means for reading each wrapper class, the first class, and the second class from the memory and writing them into an output file set, whereby the output file set results in a utility which is adapted to
• browse a source bit string,
• identify data structure elements in the source bit string, and
• handle identified data structure elements in the same order as they are located in the data structure without parsing the source bit string, and during the handling, decode each data structure element from the source bit string and encode the decoded data structure element directly into the target bit string.
