composer require okapi/aopAOP : Pemrograman Berorientasi Aspek - Paradigma pemrograman yang bertujuan untuk meningkatkan modularitas dengan memungkinkan pemisahan kekhawatiran silang.
Aspek : Kelas yang mengimplementasikan logika yang ingin Anda terapkan pada kelas target Anda. Aspek harus dijelaskan dengan atribut #[Aspect] .
Saran : Logika yang ingin Anda terapkan ke kelas target Anda. Metode saran harus dijelaskan dengan atribut #[Before] , #[Around] atau #[After] .
Bergabunglah dengan : Suatu titik dalam pelaksanaan kelas target Anda di mana Anda dapat menerapkan saran Anda. Poin bergabung didefinisikan oleh atribut #[Before] , #[Around] atau #[After] .
Pointcut : Satu set poin gabungan di mana Anda dapat menerapkan saran Anda. Pointcuts didefinisikan oleh atribut #[Pointcut] .
Tenun : Proses penerapan saran Anda ke kelas target Anda.
Aspek Implisit : Aspek diterapkan tanpa modifikasi ke kelas target. Aspek itu sendiri menentukan kelas atau metode yang berlaku untuknya.
Aspek Eksplisit Level Kelas : Aspek-aspek diterapkan dengan memodifikasi kelas target, biasanya dengan menambahkan aspek sebagai atribut ke kelas target.
Aspek Eksplisit Level Metode : Aspek-aspek diterapkan dengan memodifikasi kelas target, biasanya dengan menambahkan aspek sebagai atribut ke metode target.

Gunakan Transformers dari paket "Okapi/kode-transformer" di kernel Anda untuk memodifikasi dan mengubah kode sumber kelas PHP yang dimuat (lihat paket "Okapi/kode-transformer" untuk informasi lebih lanjut)
Paket ini memperluas paket "okapi/kode-transformer" dengan injeksi ketergantungan dan fitur AOP
AopKernel mendaftarkan banyak layanan
Layanan TransformerManager menyimpan daftar aspek dan konfigurasinya
Layanan CacheStateManager mengelola keadaan cache
Layanan StreamFilter mendaftarkan filter aliran PHP yang memungkinkan untuk memodifikasi kode sumber sebelum dimuat oleh PHP
Layanan AutoloadInterceptor membebani Composer Autoloader, yang menangani pemuatan kelas
Layanan AutoloadInterceptor mencegat pemuatan kelas
AspectMatcher cocok dengan nama kelas dan metode dengan daftar aspek dan konfigurasinya
Jika nama kelas dan metode cocok dengan suatu aspek, query status cache untuk melihat apakah kode sumber sudah di -cache
Periksa apakah cache valid:
Jika cache valid, muat kelas proksi dari cache
Jika tidak, kembalikan jalur filter stream ke layanan AutoloadInterceptor
StreamFilter memodifikasi kode sumber dengan menerapkan aspek
