Example Usage

This directory contains a comprehensive set of examples demonstrating how to use the OrderedObject library. The examples cover both basic and advanced features, with a focus on practical use cases.

Running the Examples

Each example is a standalone executable program that can be run directly:

# Run basic operations example
go run basic/main.go

# Run JSON operations example
go run json/main.go

# Run Map operations example
go run map/main.go

# Run type safety example
go run type/main.go

# Run nested structures example
go run nested/main.go

# Run array operations example
go run array/main.go

# Run error handling example
go run error/main.go

Example Structure

The examples are organized into the following functional categories:

Core Features

1. Basic Operations (basic/main.go)

   • Creating and populating objects
   • Getting and updating values
   • Deleting keys
   • Iterating through entries
   • Cloning objects
   • Configuration management example

2. JSON Operations (json/main.go)

   • Converting objects to JSON (three methods)
   • Parsing JSON into objects
   • User information handling
   • JSON serialization best practices

3. Map Operations (map/main.go)

   • Creating objects from maps
   • Converting objects to maps
   • Application settings management
   • Order preservation demonstration

4. Type Safety (type/main.go)

   • Using concrete types with generics
   • Type-safe value retrieval
   • Multiple type handling
   • Struct integration

Advanced Features

1. Nested Structures (nested/main.go)

   • Complex object hierarchies
   • Application configuration management
   • Nested value access
   • JSON serialization of nested objects

2. Array Operations (array/main.go)

   • Arrays of objects
   • Order management
   • Array element access
   • Settings item processing example

3. Error Handling (error/main.go)

   • JSON parsing errors
   • Type assertion
   • Safe value access
   • Error recovery patterns

Key Concepts Demonstrated

The examples illustrate several important concepts:

1. Order Preservation

   • Key insertion order is maintained
   • JSON serialization preserves order
   • Map conversion order handling

2. Type Safety

   • Generic type parameters
   • Type assertions
   • Struct integration
   • Type-safe value access

3. Method Chaining

   • Fluent interface pattern
   • Builder-style API
   • Immutable operations

4. Error Handling

   • JSON parsing
   • Type conversion
   • Safe value access
   • Error recovery

Best Practices

The examples demonstrate several best practices:

1. Configuration Management

   • Using ordered objects for config
   • Environment-specific settings
   • Configuration cloning

2. Data Processing

   • Type-safe data handling
   • Nested structure management
   • Array operations
   • Error handling

3. JSON Handling

   • Multiple serialization methods
   • Order preservation
   • Nested object handling
   • Error recovery

Expected Output

Each example includes clear output demonstrating:

• Object structure
• JSON serialization
• Order preservation
• Type safety
• Error handling

The output is formatted for clarity and includes comments explaining the results.

Notes

• All examples use the latest features of the library
• Error handling is demonstrated where appropriate
• Type safety is emphasized throughout
• Real-world use cases are provided
• Code is thoroughly commented
• Output is clearly formatted
