包路径：org.apache.sis.math.Vector
类名称：Vector
方法名：floatValues

Vector.floatValues介绍

[英]Copies all values in an array of single precision floating point numbers. This method is for inter-operability with APIs requiring an array of primitive type.

The default implementation invokes #floatValue(int) for all indices from 0 inclusive to #size() exclusive. Subclasses may override with more efficient implementation.
[中]复制单精度浮点数数组中的所有值。此方法用于与需要基元类型数组的API的互操作性。
默认实现为从0到#size（）exclusive的所有索引调用#floatValue（int）。子类可以通过更高效的实现进行重写。
