        LogicNode

Known Subclasses:

A class representing nodes in a logic graph

Objects which can be represented as nodes in the AST of a constraint logic graph should inherit from this class, which defines methods for overloading built-in operations.

Instance Methods

__add__(self, other)
Logic may be defined by using addition to sum logic nodes:

__and__(self, other)
Logic may be defined by using the & operator:

Overloads +

Logic may be defined by using addition to sum logic nodes:

   > query.set_logic(con_a + con_b + con_c)
   > str(query.logic)
   ... A and B and C

and(self, other)
(And operator)

source code

Overloads &

Logic may be defined by using the & operator:

   > query.set_logic(con_a & con_b)
   > sr(query.logic)
   ... A and B

or(self, other)
(Or operator)

Overloads |

Logic may be defined by using the | operator:

   > query.set_logic(con_a | con_b)
   > str(query.logic)
