Query.getPrefilterBBoxEnvelope介绍

[英]Tries to extract an Envelope from the query Filter that can be used as a pre-filtering step to narrow the result set.

The returned Envelope is determined by the following strategy:

• If the filter is an OperatorFilter, it is attempted to extract an BBOX constraint from it.
• If no BBOX constraint can be extracted from the filter (not presented or nested in Or or Not expressions, null is returned.
  [中]尝试从查询筛选器中提取信封，该信封可用作预筛选步骤，以缩小结果集。
  返回的信封由以下策略决定：
  *如果筛选器是OperatorFilter，则会尝试从中提取BBOX约束。
  *如果无法从筛选器中提取BBOX约束（未在Or或Not表达式中显示或嵌套），则返回null。
