.analyze_query(query, analyzers, multiplex_states: []) ⇒ Array<Any>
Visit query
’s internal representation, calling analyzers
along the way.
- First, query analyzers are filtered down by calling
.analyze?(query)
, if they respond to that method - Then, query analyzers are initialized by calling
.initial_value(query)
, if they respond to that method. - Then, they receive
.call(memo, visit_type, irep_node)
, where visit type is:enter
or:leave
. - Last, they receive
.final_value(memo)
, if they respond to that method.
It returns an array of final memo
values in the order that analyzers
were passed in.
