Overview

Block-based condition for custom filtering logic

Allows arbitrary filtering logic to be specified using a Ruby block. The block receives each object and should return true/false.

Examples:

Filter by attribute count

condition = BlockCondition.new { |c| c.attributes.size > 10 }
filtered = condition.apply(classes)

Complex filtering

condition = BlockCondition.new do |c|
  c.attributes.any? && c.associations.empty?
end
filtered = condition.apply(classes)
