I am using go-ethereum private network.
I am using the web3.shh.filter() and it is working fine.
I am not able to locate the filter() function in the code.
In complete go-ethereum folder, I am not able to locate it.
filter.get() produces output correctly with expiry time and all. But I am not able to locate "expiry" word in the complete folder.
Can some one help me to locate this.
