Hi Foamers,

I am very new to OpenFoam and am looking to use HashTable in my code.
I want to insert a set of keys and their associated values in a HashTable and extract them when needed.

HashTable<label, scalar> findDroplet_;//Creat a Hash-Table
findDroplet_.clear();//Hash-Table initialization
findDroplet_.resize(findDroplet_.size()+1);

I know how to create a HashTable but am stuck at inserting values and finding values in the HashTable. I hope someone who is familiar with such table can shed some light on this.

Thank you very much
Carlen.

I think resize is not necessary for a HashTable. You can access individual elements with

findDroplet_[1] = 1.234;
label index = 2;
findDroplet_[index] = 1.234;
info<<findDroplet_[2];

You use label (i.e. integer) as key. You could also use word (i. e. strings).

Thank you Joachim Herb and apologise for the late reply, I figured out how to use HashTable in OpenFoam.
