Devel::Cover::Truth_Table - Truth tables for coverage objects.

# merge contents of $and_tt into right column of $or_tt, to create

# get a (sorted) textual representation

This module provides methods for creating and merging conditional
primitives ($a && $b, $c || $d, etc.) into more complex composite
Create a new truth table based on one of the built-in primitives, which
are the subclasses of Devel::Cover::DB::Condition. $op is one of the
@coverage is a list booleans identifying which of the possible paths
have been covered.
Sorts a truth table (in place) and returns the sorted object.
and or && with three conditional paths.
or or || with three conditional paths.
or or || with two conditional paths. (i.e., when the right hand
side of the expression is a constant)
xor with four conditional paths.
Format a truth table to an array of strings for printing.
Format a truth table in HTML.
Determines the proportion of possible conditions that have coverage.
Merge entries from $sub_table into right column of table.
Merge entries from $sub_table into left column of table.
