包路径：org.geotools.data.Query
类名称：Query
方法名：setFilter

Query.setFilter介绍

[英]Sets the filter to constrain the features that will be retrieved by this Query. If no filter is set all features will be retrieved (taking into account any bounds set via #setMaxFeatures(int) and #setStartIndex(java.lang.Integer)).

The default is Filter#INCLUDE.
[中]设置过滤器以约束此查询将检索的要素。如果未设置过滤器，将检索所有功能（考虑通过#setMaxFeatures（int）和#setStartIndex（java.lang.Integer）设置的任何边界）。
默认设置为过滤器#包含。
