[resolved] Binary File as Input

Anonymous — Sat, 01 Oct 2016 20:16:20 GMT

Hi, from what I've read in other forum entries, it's not possible to use binary files as an input. I DO know the exact data structure and I have a little plain Java source snippet which is capable extracting the data from the binary file.

Is there any way I can use that little Java snippet as a generator for an input, just like the tFileInput..... components are?
In an ideal world, I would fill the output_row fields within each iteration of my Java loop, just like that:

output_row.field1 = field1;
output_row.field2 = field2;
...

Any advise would be appreciated.

I think I've got the solution.
[list=1]

tJava: create an ArrayList

tJava: loops over the binary file and put elements into the ArrayList

tJava: at the end of the loop, put the ArrayList into the global Map

Later:
tJavaFlex / Start Code:

java.util.Iterator<Tick> al = ((java.util.ArrayList<Tick>)globalMap.get("ticks")).iterator();

while (al.hasNext()) {

tJavaFlex / Main Code:

Tick ti = al.next();
row2.milliseconds = ti.getMilliseconds();
row2.ask = ti.getAsk();
row2.bid = ti.getBid();
row2.askv = ti.getAskv();
row2.bidv = ti.getBidv();

tJavaFlex / End Code:

And that creates the flow. I think the memory usage peaks a little, but the files are not longer than 1-2MB, so that shouldn't be too much of an issue. Very cool, this brings me a huge leap forward. Thank you Talend!!
