Comparator接口定义在java.util包下,包含了两个方法:compare()和equals()。compare()方法的定义如下:intcompare(Object obj1, Object obj2)obj1和obj2是需要被比较的两个对象,如果两个对象【相等】,则该方法返回0,如果obj1【大于】obj2,则返回一个正值,否则返回一个负值。通过重写该方法,可以自定义对象排序的方...

The contextCompare function is a context query that returns the rank of the current shape geometry among other labeled shape geometries according to a specific comparator.
