BigIntegerToInt128PropertyHandler

A property handler that maps a 128-bit integer column, which drivers expose as a BigInteger, into a Int128 property.

A property handler that maps a 128-bit integer column (for example, the Firebird INT128 type, which drivers expose as a BigInteger) into an Int128 property.

This handler is compiled only for .NET 8 and later. It is not available on the netstandard2.0 target of the RepoDb package.

Usability

Bind the handler to the property that maps to the INT128 column.

Attribute

public class Counter
{
    public int Id { get; set; }

    [Map("total"), PropertyHandler(typeof(BigIntegerToInt128PropertyHandler))]
    public Int128 Total { get; set; }
}

Once bound, the library invokes the handler automatically when the property is read or written.

using (var connection = new FbConnection(connectionString))
{
    connection.Insert(new Counter { Id = 1, Total = Int128.MaxValue });
    var counter = connection.Query<Counter>(e => e.Id == 1).First();
}

Fluent Mapping

To configure via FluentMapper:

FluentMapper
    .Entity<Counter>()
    .PropertyHandler<BigIntegerToInt128PropertyHandler>(e => e.Total);

Property Level Mapping

To configure via PropertyHandlerMapper:

PropertyHandlerMapper.Add<Counter, BigIntegerToInt128PropertyHandler>(e => e.Total, new BigIntegerToInt128PropertyHandler(), true);

Type Level Mapping

To apply the handler to every property of the type Int128:

PropertyHandlerMapper.Add<Int128, BigIntegerToInt128PropertyHandler>(new BigIntegerToInt128PropertyHandler(), true);
