The Source Code of "SAMPLE"

Dear pigs,

I want to know about the implementation of "SAMPLE".

Could you kindly tell me where shall I see the source code of "SAMPLE"?

Or tell me some links that describe the implementation of "SAMPLE".


many thanks!

This link has some background:
http://wiki.apache.org/pig/PigSampler

And these are the sampler classes:
org.apache.pig.impl.builtin.SampleLoader
org.apache.pig.impl.builtin.PoissonSampleLoader
org.apache.pig.impl.builtin.RandomSampleLoader

I believe SAMPLE uses RandomSampleLoader.
