IRecordDelegates

IRecordDelegates contains delegates for record. (namespace Avalanche.Utilities.Record).

/// <summary>Record delegates</summary>
public interface IRecordDelegates
{
    /// <summary>Record Type</summary>
    Type RecordType { get; set; }
    /// <summary>Creates record with initial values <![CDATA[Func<object[], Record>]]></summary>
    Delegate? RecordCreate { get; set; }
    /// <summary>Field delegates</summary>
    IFieldDelegates[]? FieldDelegates { get; set; }
    /// <summary></summary>
    IRecordDescription? RecordDescription { get; set; }
}

/// <summary>Record delegates</summary>
public interface IRecordDelegates<Record> : IRecordDelegates
{
    /// <summary>Creates record with initial values <![CDATA[Func<object[], Record>]]></summary>
    new Func<object[], Record>? RecordCreate { get; set; }
}

RecordDelegates is the default implementation.

IRecordDelegates<MyClass> recordDelegates =
    new RecordDelegates<MyClass>
    {
        RecordCreate = null,
        FieldDelegates = new IFieldDelegates[0],
        RecordDescription = null
    }.SetReadOnly();

There is a setter method for each field.

IRecordDelegates recordDelegates =
    RecordDelegates
    .Create(typeof(MyClass))
    .SetRecordCreate(null)
    .SetFieldDelegates(null)
    .SetRecordDescription(null)
    .SetReadOnly();

.Clone() makes a copy.

IRecordDelegates clone = recordDelegates.Clone().SetReadOnly();

.CreateRecordDelegates() and .CreateRecordDelegates<T>() create delegates.

IRecordDelegates<MyClass> recordDelegates = recordDescription.CreateRecordDelegates<MyClass>();

Delegates can be also be created and cached with IRecordDescription.

IRecordDelegates<MyClass> recordDelegates = RecordProviders.Cached.GetRecordDelegates<MyClass>().AssertValue();

CreateRecord delegate constructs record.

MyClass myClass = recordDelegates.RecordCreate!(new object[] { 5 });

.FieldDelegates property contains a field specific delegates

FieldRead<MyClass, int> reader =
    (FieldRead<MyClass, int>)
    recordDelegates
    .FieldDelegates!
    .GetByName("value")
    .FieldRead!;
// Read
int value = reader(ref myClass);

public class MyClass
{
    public int value;

    public MyClass(int value)
    {
        this.value = value;
    }
}
