The id related to the statement, used as part of the prepared statement name.

last_seen[RW]

The last time this statement was seen by the cache, persumably the last time it was executed.

num_executes[RW]

The total number of executions since the statement entered the cache.

Public Class Methods

new(cache_id) click to toggle source

Used when adding entries to the cache, just sets their id. Uses 0 for num_executes since that is incremented elsewhere. Does not set last_seen since that is set elsewhere to reduce branching.

# File lib/sequel/extensions/pg_statement_cache.rb, line 59
def initialize(cache_id)
  @num_executes = 0
  @cache_id = cache_id
end

Public Instance Methods
