checksum-process

Vocabulary

checksums.process

Class description

This is an instance of the block-checksum mixin. It calculates checksums by running a console utility as described in the launch-desc slot, piping data to it and receiving the output at the end. Each call to initialize-checksum-state starts a new external process, which is represented by a process-state instance. The latter also holds the resulting checksum.
