类名称：Rule
方法名：setSymbolizers

Rule.setSymbolizers介绍

[英]The symbolizers contain the actual styling information for different geometry types. A single feature may be rendered by more than one of the symbolizers returned by this method. It is important that the symbolizers be applied in the order in which they are returned if the end result is to be as intended. All symbolizers should be applied to all features which make it through the filters in this rule regardless of the features' geometry. For example, a polygon symbolizer should be applied to line geometries and even points. If this is not the desired beaviour, ensure that either the filters block inappropriate features or that the FeatureTypeStyler which contains this rule has its FeatureTypeName or SemanticTypeIdentifier set appropriately.
[中]符号器包含不同几何体类型的实际样式信息。单个特征可以由该方法返回的多个符号呈现。如果最终结果如预期的那样，则必须按照返回符号的顺序应用符号。所有符号都应应用于通过本规则中过滤器的所有特征，无论特征的几何结构如何。例如，多边形符号器应应用于直线几何图形和偶数点。如果这不是所需的beaviour，请确保过滤器阻止不适当的功能，或者包含此规则的FeatureTypeStyler的FeatureTypeName或SemanticTypeIdentifier设置正确。
