是否可以使用requestfactory直接传输com.vividsolutions.jts.geom.Geometry？ [英] Is com.vividsolutions.jts.geom.Geometry directly transportable using requestfactory?

问题描述

是否可以使用requestfactory直接传输com.vividsolutions.jts.geom.Geometry，还是必须对我的entityproxy使用值代理？

Is com.vividsolutions.jts.geom.Geometry directly transportable using requestfactory or do i have to use a value proxy with my entityproxy?

推荐答案

根据 http://www.gwtproject.org/doc/latest /DevGuideRequestFactory.html#transportable ，您必须使用 ValueProxy 。

但它似乎不可能绕过几何图形，因为设置者比getter少（即几何不能通过调用setter从一个空对象重新构造）。所以你可能不得不运输几何图形的文本表示或使用包装器/构建器。

But it doesn't seem possible to roundtrip the geometry as there are less setters than getters (i.e. the geometry cannot be re-constructed from an empty object just by calling setters); so you'd probably have to transport the textual representation of the geometry instead or use wrappers/builders.
