Record Components:
name - signature name | 签名名称
reason - signing reason | 签名原因
location - signing location | 签名位置
contactInfo - contact information | 联系信息
signDate - signing date | 签名日期
certificates - certificate chain | 证书链
timestampInfo - timestamp info (if present) | 时间戳信息
isValid - whether signature is valid | 签名是否有效
coversWholeDoc - whether signature covers entire document | 签名是否覆盖整个文档
revisionNumber - revision number | 修订号
public record SignatureInfo(String name, String reason, String location, String contactInfo, Instant signDate, List<X509Certificate> certificates, TimestampInfo timestampInfo, boolean isValid, boolean coversWholeDoc, int revisionNumber) extends Record
Signature Information 签名信息

Contains details about a PDF digital signature.

包含 PDF 数字签名的详细信息。

Features | 主要功能:

  • Signature metadata (name, reason, location, contact) - 签名元数据（名称、原因、位置、联系方式）
  • Certificate chain access - 证书链访问
  • Timestamp information - 时间戳信息
  • Validity and coverage status - 有效性和覆盖状态

Usage Examples | 使用示例:

SignatureInfo info = SignatureInfo.builder()
    .name("Contract")
    .reason("Approval")
    .valid(true)
    .build();

String signer = info.getSignerName();
boolean hasTs = info.hasTimestamp();

Security | 安全性:

  • Thread-safe: Yes — immutable record - 线程安全: 是 — 不可变记录
  • Null-safe: Partial — fields may be null - 空值安全: 部分 — 字段可能为空
  • Defensive copies: Certificate list is copied on construction - 防御性拷贝: 证书列表在构造时进行拷贝

      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
