Interface SignatureField

All Superinterfaces:
FormField
public non-sealed interface SignatureField extends FormField
Signature Form Field 签名表单字段

Features | 主要功能:

  • Signature status check - 签名状态检查
  • Signer name, date, reason, and location access - 签名者名称、日期、原因和位置访问

Usage Examples | 使用示例:

SignatureField sig = (SignatureField) form.getField("signature1");
if (sig.isSigned()) {
    String signer = sig.getSignerName();
    String date = sig.getSignDate();
}

Security | 安全性:

  • Thread-safe: Depends on implementation - 线程安全: 取决于实现
  • Null-safe: Depends on implementation — getters may return null if not signed - 空值安全: 取决于实现 — 未签名时获取方法可能返回空
