Class
    Foam::Function1s::integratedNonUniformTable
 
Description
    Non-uniform tabulated property function that linearly interpolates between
    the values.
 
    To speed-up the search of the non-uniform table a uniform jump-table is
    created on construction which is used for fast indirect addressing into
    the table.
 
Usage
    \table
        Property    | Description
        values      | List of value pairs
    \endtable
 
    Example for the density of water between 280 and 350K
    \verbatim
    rho
    {
        type    integratedNonUniformTable;
 
        values
        (
            (280 999.87)
            (300 995.1)
            (350 973.7)
        );
    }
