    Post Hash Key Comparisions for two objects

    Hi,

    Please Help..

    I want to generate a Hash key for a [ Nested Hierarchical nodes].
    Can you suggest me a lightweight non-cryptographic hash map functions which generate a key, so that I can use this hashkey to comparison purposes.

    NOTE: Security is not a concern for me, I just want to create a Unique ID.

    I appreciate the help.

    Thanks

    What kind of objects are the hash keys for? If you want each new object to have a unique key, create the key by using a static int that is incremented for each object created.
    use this hashkey to comparison purposes.
    What types of objects would be expected to have the same key values?
    If you don't understand my answer, don't ignore it, ask a question.
