Geometry.covers介绍

[英]Tests whether this geometry covers the argument geometry.

The covers predicate has the following equivalent definitions:

  • Every point of the other geometry is a point of this geometry.

  • The DE-9IM Intersection Matrix for the two geometries matches at least one of the following patterns:

  • [T*****FF*]

    • [*T****FF*]
    • [***T**FF*]
    • [****T*FF*]

  • g.coveredBy(this) = true
    (covers is the converse of #coveredBy)
    If either geometry is empty, the value of this predicate is false.

This predicate is similar to #contains, but is more inclusive (i.e. returns true for more cases). In particular, unlike contains it does not distinguish between points in the boundary and in the interior of geometries. For most situations, covers should be used in preference to contains. As an added benefit, covers is more amenable to optimization, and hence should be more performant.
[中]测试此几何图形是否包含参数几何图形。
covers谓词具有以下等效定义：
*其他几何图形的每个点都是此几何图形的一个点。
*两种几何图形的DE-9IM相交矩阵至少匹配以下模式之一：

  • [T*****FF*]
  • [*T****FF*]
  • [***T**FF*]
  • [****T*FF*]
  • g.coveredBy(this) = true
    （covers是#coveredBy的反义词）
    如果任一几何体为空，则此谓词的值为false。
    该谓词类似于#contains，但更具包容性（即对于更多情况返回true）。特别是，与contains不同，它不区分几何体边界和内部的点。对于大多数情况，covers应该优先于contains使用。作为一个额外的好处，covers更易于优化，因此应该更高效。
