Overview

Collection wrapper for sets of attributes.

## Purpose

Provides a unified interface for working with collections of attributes. Uses Ruby Set internally for uniqueness but exposes Array-like interface.

## Usage

Used internally by:

  • Request/Response factories (to store attributes)

  • Attribute::Base (to store nested attributes)

## Methods

Delegates common collection methods to internal Set:

  • ‘<<` - Add attribute

  • ‘each`, `map`, `select`, `reject` - Iteration

  • ‘find`, `first` - Access

  • ‘size`, `empty?` - Size checks

  • ‘to_h` - Convert to hash

Custom methods:

  • ‘exists?` - Returns true if collection is not empty

## Example

collection = Collection.new
collection << Attribute::Base.new(:name, :string)
collection << Attribute::Base.new(:age, :integer)
collection.size  # => 2
collection.exists?  # => true
