本文整理了Java中org.geotools.xml.Encoder类的一些代码示例，展示了Encoder类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Encoder类的具体详情如下：
包路径：org.geotools.xml.Encoder
类名称：Encoder

Encoder介绍

[英]Encodes objects as xml based on a schema.

The function of the encoder is to traverse a tree of objects seializing them out as xml as it goes. Navigation and serialization of the tree is performed by instances of org.geotools.xml.Binding which are bound to types in the schema.

To execute the encoder, one must have 3 bits of information:

  1. The root object in the tree to be encoded
  2. The schema / configuration of the intsance document being encoded.
  3. A name of the element defined in the schema which corresponds to the root object in the tree.

As an exmaple, consider the encoding of a org.opengis.filter.Filterinstance.

//instantiate hte configuration for the filter schmea 
Configuration configuration = new OGCConfiguration(); 
//create the encoder 
Encoder encoder = new Encoder( configuration ); 
//get a filter 
Filter filter = ...; 
//get the name of the 'filter' element in the schema 
QName name = new QName( "http://www.opengis.net/ogc", "Filter" ); 
//encode 
encoder.encode( filter, name );

[中]基于模式将对象编码为xml。
编码器的功能是遍历一棵对象树，并将它们作为xml进行序列化。树的导航和序列化由org的实例执行。地理工具。xml。绑定到架构中的类型的绑定。
要执行编码器，必须有3位信息：
1.树中要编码的根对象
1.正在编码的intsance文档的架构/配置。
1.模式中定义的元素的名称，对应于树中的根对象。
作为一个Excel，考虑一个ORG的编码。opengis。滤器过滤状态。

//instantiate hte configuration for the filter schmea 
Configuration configuration = new OGCConfiguration(); 
//create the encoder 
Encoder encoder = new Encoder( configuration ); 
//get a filter 
Filter filter = ...; 
//get the name of the 'filter' element in the schema 
QName name = new QName( "http://www.opengis.net/ogc", "Filter" ); 
//encode 
encoder.encode( filter, name );
