class JSONStore
JSONStore
provides the same functionality as PStore, except it uses JSON to dump objects instead of Marshal. Example use:
store = JSONStore.new("json_store/json_test.json") # Write store.transaction { store["key"]="value" } # Read value = store.transaction { store["key"] } puts value # prints "value" # Dump the whole store hash = store.transaction { store.to_h } p hash # prints {"key" => "value"}
Constants
- EMPTY_MARSHAL_CHECKSUM
- EMPTY_MARSHAL_DATA
