Method: Predicate#attr_split

Defined in:
lib/predicate.rb

#attr_split ⇒ Object

Returns a hash ‘(attr -> Pattr)` associating attribute names to predicates, so that each predicate Pattr only makes reference to the corresponding attribute name attr, while the conjunction of `Pattr`s is still equivalent to the original predicate.

A nil key may map a predicate that still makes references to more than one attribute.
