    Enums: How to Work With .NET Enum Type

    To use .NET enums in your Java project, javonet API provides special NEnum type. Using this class you can keep the reference of particular enum value, get/set the enum value, pass the enum value as method argument or compare enum values.

    To initialize reference to .NET enum type you can use the NEnum(String enumTypeName, String enumValue) constructor. As first argument you must provide enum type name with or without namespace. When namespace is not provided Javonet will automatically lookup the enum type in all loaded assemblies, if there is only one type with provided name it will be used. In second argument selected enum value should be provided.

    How to initialize NEnum object

    Sample enum definition in .NET:

    public enum SampleEnum 
    {
        ValueOne,
        ValueTwo,
        ValueThree
    }

    Enum usage in Java:

    //Create instance of enum value
    NEnum sampleEnumValueOne = new NEnum("SampleEnum","ValueOne");
    
    //Display enum value name
    System.out.println(sampleEnumValueOne.getValueName()); //displays "ValueOne"
    
    //Display enum value
    System.out.println(sampleEnumValueOne.getValue()); //displays "0"

    How to get/set enum value and pass enum as method argument

    Sample code in .NET

    public enum SampleEnum 
    {
        ValueOne,
        ValueTwo,
        ValueThree
    }
    public class Sample
    {
         public SampleEnum EnumField { get; set; }
         public void MethodA(SampleEnum value)
         {
              Console.Out.WriteLine(value);
         }
    }

    Usage in Java

    NObject sampleObj = Javonet.New("Sample");  
    
    //Set enum as property value  
    sampleObj.set("EnumField",new NEnum("SampleEnum","ValueTwo"));  
    
    //Get enum from property  
    NEnum enumValue = sampleObj.<NEnum>get("EnumField"); 
    
    System.out.println(enumValue.getValueName());
    System.out.println(enumValue.getValue()); 
    
    //Pass enum as method argument  
    sampleObj.invoke("MethodA",enumValue);  
    
    //Check enum value  
    if (enumValue.equals(new NEnum("SampleEnum","ValueTwo")))
    {  
    	 System.out.println("Enum returned from EnumField equals ValueTwo");  
    }  
    else  
    {  
    	 System.out.println("Enum returned from EnumField does not equal to ValueTwo");  
    }
