本文整理了Java中org.geotools.referencing.CRS.lookupIdentifier()方法的一些代码示例，展示了CRS.lookupIdentifier()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。CRS.lookupIdentifier()方法的具体详情如下：
包路径：org.geotools.referencing.CRS
类名称：CRS
方法名：lookupIdentifier

CRS.lookupIdentifier介绍

[英]Looks up an identifier of the specified authority for the given CoordinateReferenceSystem). This method is similar to #lookupIdentifier(IdentifiedObject,boolean)(object, fullScan) except that the search is performed only among the factories of the given authority.

If the CRS does not have an ReferenceIdentifier which corresponds to the Citations#EPSG authority, then:

  • if fullScan is true, then this method scans the factories in search for an object #equalsIgnoreMetadata, to the given object. If one is found, its identifier is returned.
  • Otherwise (if fullScan is false or if no identifier was found in the previous step), this method returns null.
    [中]查找给定CoordinationReferenceSystem）的指定权限的标识符。此方法与#lookupIdentifier(IdentifiedObject,boolean)(object, fullScan)类似，只是搜索仅在给定权限的工厂中执行。
    如果CRS没有与引文#EPSG机构对应的参考标识，则：
    *如果fullScan为true，则此方法扫描工厂以搜索给定对象的对象#equalsIgnoreMetadata。如果找到一个，则返回其标识符。
    *否则（如果fullScan为false或在上一步中未找到标识符），此方法将返回null。
