TableSource#

TableSource loads an .ltk actuarial table file from disk and exposes the raw decrement arrays and metadata for use by LifeTable, DisabilityTable, and ExitTable constructors.

Table files are located in the directory configured by tables_path (default: absolute path to actuarial_tables/ in the working directory at the time of the first Config() call). A disk-read cache keyed on file path and modification time avoids redundant I/O for repeated access to the same table within a session.

Note

TableSource is primarily an internal component. Users normally access table data through LifeTable and its siblings rather than constructing a TableSource directly.
