Testing library
This library has an example that you can execute. This example is a metadata converter that can encode or decode metadata. If you want to encode, the input file must respect one of the formats developed (for this first version, only could use JSON format) and will return a binary file with metadata encoded. On the other hand, if you want to decode the program receives a binary file and converts it to the format file selected (for this first version, only could use JSON format).
The executable is located on /misb-library/examples/misb/ or if you want to compile and execute the example file out of the project. The path of the example is located on /misb-library/examples/misb/misb-converter.cpp. To compile the example we suggest you follow the next Makefile:
FLAGS:=`pkg-config --cflags --libs misb-0.0` misb-converter: misb-converter.cpp g++ -o misb-converter misb-converter.cpp $(FLAGS)
Encode command
 | Enrique: Please show the JSON file, to let the viewer understand the whole process. Show input (JSON) and output byte-stream (please remove this box when addressed) |
To perform the encoding, the following command is executed. Where the --encode flag indicates that encoding is to be performed. The -i flag indicates the input file, where the metadata must be raw without encoding. On the other hand, the -o flag indicates the output file, which contains the encoded bytes in a binary file. The --verbose flag shows the KLV bytes encoded on the terminal.
./misb-converter --verbose --encode -i misb_ST0601_sample.json -o klv.bin
Decode command
| Enrique: The same here, show input (byte-stream) and output (JSON generated) (please remove this box when addressed) |
To perform the decoding, the following command is executed. Where the --decode flag indicates that decoding is to be performed. The -i flag indicates the input file, where the metadata must be encoded. The -o flag indicates the output file, which contains the metadata decoded.
./misb-converter --decode -i klv.bin -o output.json
