INTERFACE

Methods

Constructor
$tm = TM::Materialized::JTM->new (...);

The constructor expects a hash as described in TM::Materialized::Stream, with one additional key/value parameter:

  • format (choices: "json", "yaml")

    This option controls whether the JTM data is treated as being in JSON format or in YAML (which is a superset of JSON). This applies to both reading and writing of map data.

    The default value is "json".

format
$tm->format('json');

$curformat=$tm->format;

This method gets or sets the format parameter for future operations. Possible choices: "json", "yaml".
