本文整理了Java中org.geotools.feature.Feature.getNumberOfAttributes()方法的一些代码示例，展示了Feature.getNumberOfAttributes()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。Feature.getNumberOfAttributes()方法的具体详情如下：
包路径：org.geotools.feature.Feature
类名称：Feature
方法名：getNumberOfAttributes

Feature.getNumberOfAttributes介绍

[英]Get the number of attributes this feature has. This is NOT simply a convenience method for calling getFeatureType().getNumberOfAttributes(). This is the same as calling getAttributes(null).length. This represents the number of actual attribute values in the feature, and may differ from the number of AttributeTypes defined in the FeatureType based on the multiplicity of the AttributeTypes.
[中]获取此功能具有的属性数。这不仅仅是调用getFeatureType（）的方便方法。getNumberOfAttributes（）。这与调用getAttributes（null）相同。长这表示要素中实际属性值的数量，可能不同于基于属性类型的多重性在FeatureType中定义的属性类型的数量。
