本文整理了Java中org.jooq.Field.getConverter()方法的一些代码示例，展示了Field.getConverter()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Field.getConverter()方法的具体详情如下：
包路径：org.jooq.Field
类名称：Field
方法名：getConverter

Field.getConverter介绍

[英]The field's underlying Converter.

By default, all fields reference an identity-converter Converter<T, T>. Custom data types may be obtained by a custom Converter placed on the generated TableField.
[中]字段的基础转换器。
默认情况下，所有字段都引用标识转换器Converter<T, T>。自定义数据类型可以通过放置在生成的TableField上的自定义转换器获得。

private <K> void copyValueIntoRecord(T outputRecord, Record inputRecord, Field<K> field, int idx)
{
 outputRecord.setValue(field, inputRecord.getValue(idx, field.getConverter()));
}
