public interface HotboxPoller
A hotbox poller polls (scans) a directory on a recurring interval (e.g. 5 seconds). If it finds a file in the hotbox directory that is younger (more recent) than an associated file in another directory, the poller initiates a process on the hotbox file.
In the context of the Exec package, a hotbox directory is polled for JSON
files. New files are sent to the HTTP API /makeRDG for conversion into
RDG
s. This allows one to wrap a legcay program as a semantic web
service by simply dropping an appropriately parameterized JSON
RDG
description into the hotbox directory.
