#initialize(fn_template, options = {}) ⇒ Membership

Membership In order to give information about files in relation to the sequence signature, we need to collect all the filenames the user asks for, and all the filenames on disk that match the sequence mask (the filename part of the sequence signature). Thewn we can determine whether the file was (found), (misssing), or (extra) i.e. existing but not asked for

Each element in the array returned by this method is a 3 element sub array that has the following form:

“filename”, <:found|:missing|:extra>, frame_number

It is sorted on the frame_number, which is an integer

Instance Method Details

#assessment_message ⇒ Object

generate a message from the filename matrix - something like this: ../test/a/006_057_s3d_lf_r06.#.dpx [found: 13] [missing: 3] [extra: 17] where the found missing and extra sections are color coded according to whether there were files present with that attribute
