Get Database Directory Corresponding To a Fit¶

node_table¶

is the node_table for this cascade as a list'' of ``dict. It can’t be None.

split_reference_table¶

is the split_reference_table as a list of dict. It can’t be None. If the list has length zero, we say that the table is empty.

node_split_set¶

If split_reference_table is empty, this argument must be None. Otherwise it is a set of int containing the node_id values that appear in the node_spit table.

root_node_id¶

is the node_id for the root_node.

root_split_reference_id¶

If split_reference_table is empty, this argument must be None. Otherwise it is an int specifying the split_reference_id that the root node corresponds to.

fit_node_id¶

This argument is an int is the node_id for the fit_node.

fit_split_reference_id¶

If split_reference_table is empty, this argument must be None. Otherwise it is an int specifying the split_reference_id that the fit corresponds to.

database_dir¶

The return value is a str containing the directory, relative to the result_dir, where the database corresponding to the fit is (or will be) located. In other words, the fit database has the following path:

result_dir/ database_dir/dismod.db
