类名称：Geometry
方法名：getDimension

Geometry.getDimension介绍

[英]Returns the dimension of this geometry. The dimension of a geometry is is the topological dimension of its embedding in the 2-D Euclidean plane. In the JTS spatial model, dimension values are in the set {0,1,2}.

Note that this is a different concept to the dimension of the vertex Coordinates. The geometry dimension can never be greater than the coordinate dimension. For example, a 0-dimensional geometry (e.g. a Point) may have a coordinate dimension of 3 (X,Y,Z).
[中]返回此几何图形的尺寸。几何体的维数是其嵌入二维欧氏平面的拓扑维数。在JTS空间模型中，维度值位于集合{0,1,2}中。
请注意，这与顶点坐标的尺寸是不同的概念。几何图形尺寸永远不能大于坐标尺寸。例如，0维几何图形（例如点）的坐标尺寸可能为3（X、Y、Z）。
