gets the function type number . type 0 - sampled function , uses a table of sample values to define the function . various techniques are used to interpolate values between the sampled values . type 2 - exponential interpolation , defines a set of coeffiecients for an exponential function . type 3 - stitching function , a combination of other functions , partitioned across a domain . type 4 - calculator function , uses operators from the postscript language do describe an arithmetic expression . concode_field_sep Logger logger concode_elem_sep float[] domain concode_elem_sep float[] range concode_elem_sep int functionType concode_field_sep float[] getDomain concode_elem_sep float[] getRange concode_elem_sep Function getFunction concode_elem_sep float interpolate concode_elem_sep float[] calculate
