Fieldable.binaryValue介绍

[英]The value of the field in Binary, or null. If null, the Reader value, String value, or TokenStream value is used. Exactly one of stringValue(), readerValue(), binaryValue(), and tokenStreamValue() must be set.
[中]字段的二进制值，或null。如果为null，则使用读取器值、字符串值或令牌流值。必须设置stringValue（）、readerValue（）、binaryValue（）和tokenStreamValue（）中的一个。
