chc.util.IndexedTable module

class chc.util.IndexedTable.IndexedTable(name: str)[source]

Bases: chc.util.IndexedTable.IndexedTableSuperclass

Table to provide unique indices to objects represented by a key string.

The table can be checkpointed and reset to that checkpoint with - set_checkpoint - reset_to_checkpoint

Note: the string encodings use the comma as a concatenation character, hence: the comma character cannot be used in any string representation.
