类 CopyOptions

java.lang.Object

io.polaris.core.lang.copier.CopyOptions

所有已实现的接口:

Cloneable

public class CopyOptions
extends Object
implements Cloneable

默认规则（与BeanCopier默认规则尽量保持一致）：

• ignoreError: true
• ignoreNull: true
• override: true
• ignoreCase: false
• ignoreCapitalize: false
• enableUnderlineToCamelCase: false
• enableCamelToUnderlineCase: false
• enableConverter: true

从以下版本开始:

1.8
