本文整理了Java中com.datastax.driver.core.TypeCodec.cfloat()方法的一些代码示例，展示了TypeCodec.cfloat()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。TypeCodec.cfloat()方法的具体详情如下：
包路径：com.datastax.driver.core.TypeCodec
类名称：TypeCodec
方法名：cfloat

TypeCodec.cfloat介绍

[英]Return the default codec for the CQL type float. The returned codec maps the CQL type float into the Java type Float. The returned instance is a singleton.
[中]返回CQL类型浮点的默认编解码器。返回的编解码器将CQL类型的浮点映射为Java类型的浮点。返回的实例是一个单例。
