Detailed Description

An expressionset can implement several different sets of identities on expressions.

This type represents one of those sets.

Could have been a simple enum class, but having a constructor is helping to select the default identities other than the first one.

Member Enumeration Documentation

enum vcsn::rat::identities::ids_t

Enumerator
none	Strictly obey to the syntax.
trivial	Trivial identities only.
associative	Trivial, plus associativity of add and product.
linear	Associative plus commutativity, and "idempotence" for add.
distributive	Traditional plus distribution. Used for series identities.
deflt	The default value.
