Binary Data Structure Marshalling and Unmarshalling

[Pratik Thacker <pr...@gmail.com>]

We need to decode and encode binary data structure.
We explored several data formats available in
http://camel.apache.org/data-format.html. But couldn't find relevant data
format for binary structured record.

For example:
If my data structure of a record is like:
SampleStructure bytes(12){
       int num1: bytes(1);
       int num2: bytes(2);
       string results: bytes(9);
}
And Data is like:
Record-1{
      num1: 100;
      num2: 300;
      results: "Test_Test";
}
For above sample data, file would be of 12 bytes containing one record.
* 1st byte representing byte form of integer 100.
* 2nd and 3rd byte representing byte form of integer 300. Here, it would be
great if we have choice to choose among big-endian and little-endian format.
* next 9 bytes representing byte form of ascii value of each character of
the string "Test_Test".

Similarly a file can contain multiple consecutive records.

Please suggest if we can unmarshal such formats and directly get a POJO
object, just like we get it for the csv, xml or flat file formats. Here are
the references we already explored and found it to be non-relevant for our
case.

If the data formats you’ve listed don’t work, I’d guess you’ll need to write your own DataFormat (http://camel.apache.org/custom-dataformat.html <http://camel.apache.org/custom-dataformat.html>)
