Class ByteArrayAttachment

java.lang.Object

cloud.opencode.base.email.attachment.ByteArrayAttachment

All Implemented Interfaces:

Attachment

public final class ByteArrayAttachment
extends Object
implements Attachment

Byte Array Email Attachment 字节数组邮件附件

Attachment implementation for in-memory byte data.

内存字节数据的附件实现。

Features | 主要功能:

• In-memory data - 内存数据
• No file system dependency - 无文件系统依赖
• Defensive copy for security - 防御性拷贝确保安全

Usage Examples | 使用示例:

byte[] data = generatePdfReport();
Attachment attachment = new ByteArrayAttachment("report.pdf", data, "application/pdf");

Security | 安全性:

• Thread-safe: Yes - 线程安全: 是
• Immutable: Yes (defensive copy) - 不可变: 是（防御性拷贝）

Since:

JDK 25, opencode-base-email V1.0.0
