Keterangan

Sink saluran menyediakan titik plug-in yang memungkinkan akses ke pesan mendasar yang mengalir melalui saluran serta aliran yang digunakan oleh mekanisme transportasi untuk mengirim pesan ke objek jarak jauh. Sink saluran ditautkan bersama dalam rantai penyedia sink saluran, dan semua pesan saluran mengalir melalui rantai sink ini sebelum pesan diserialisasikan dan diangkut.

Kelas ini membuat permintaan tautan dan permintaan warisan di tingkat kelas. SecurityException dilemparkan ketika pemanggil langsung atau kelas turunan tidak memiliki izin infrastruktur. Untuk detail tentang tuntutan keamanan, lihat Permintaan Tautan dan Permintaan Warisan.

Catatan Bagi Implementer

Ketika Anda mewarisi dari BaseChannelSinkWithProperties, Anda harus menerapkan Keys properti dan Item[Object] properti .
