This module uses JSON to Perl data structures into JSON strings, and to decode JSON strings into Perl data structures.
encode()
$bytes = $serializer->encode($ref); $bytes = $serializer->encode($str);
The "encode()" method converts array and hash refs into their JSON equivalents. If a string is passed in, it is returned as the UTF8 encoded version of itself. The empty string and undef
are returned as is.
encode_pretty()
$bytes = $serializer->encode_pretty($ref); $bytes = $serializer->encode_pretty($str);
Works exactly as "encode()" but the JSON output is pretty-printed.
encode_bulk()
$bytes = $serializer->encode_bulk([\%hash,\%hash,...]); $bytes = $serializer->encode_bulk([$str,$str,...]);
The "encode_bulk()" method expects an arry ref of hashes or strings. Each hash or string is processed by "encode()" then joined together by newline characters, with a final newline character appended to the end. This is the special JSON format used for bulk requests.
decode()
$var = $serializer->decode($json_bytes); $str = $serializer->decode($bytes);
If the passed in value looks like JSON (ie starts with a {
or [
character), then it is decoded from JSON, otherwise it is returned as the UTF8 decoded version of itself. The empty string and undef
are returned as is.
