类名称：WKTFormat

WKTFormat介绍

[英]Parser and formatter for Well Known Text (WKT) strings. This format handles a pair of Parser and Formatter, used by the parse(…) and format(…) methods respectively. WKTFormat objects allow the following configuration:

• The preferred authority of IdentifiedObject#getName() to format (see Formatter#getNameAuthority() for more information).
• The Symbols to use (curly braces or brackets, etc).
• The Transliterator to use for replacing Unicode characters by ASCII ones.
• Whether ANSI X3.64 colors are allowed or not (default is not).
• The indentation.
  String expansion Because the strings to be parsed by this class are long and tend to contain repetitive substrings, WKTFormat provides a mechanism for performing string substitutions before the parsing take place. Long strings can be assigned short names by calls to the #addFragment(String,String) method. After fragments have been added, any call to a parsing method will replace all occurrences (except in quoted text) of tokens like $foo by the WKT fragment named "foo".

Example: In the example below, the $WGS84 substring which appear in the argument given to the parseObject(…) method will be expanded into the full GeodeticCRS[“WGS84”, …]string before the parsing proceed. #addFragment("deg", "AngleUnit[“degree”, 0.0174532925199433]"); #addFragment("lat", "Axis[“Latitude”, NORTH, $deg]"); #addFragment("lon", "Axis[“Longitude”, EAST, $deg]"); #addFragment("MyBaseCRS", "GeodeticCRS[“WGS84”, Datum[…etc…], CS[…etc…], $lat, $lon]"); Object crs = #parseObject(String)("ProjectedCRS[“Mercator_1SP”, $MyBaseCRS,…etc…]"); Note that the parsing of WKT fragment does not always produce the same object. In particular, the default linear and angular units depend on the context in which the WKT fragment appears.
Limitations

• The WKT format is not lossless! Objects formatted by WKTFormat are not guaranteed to be identical after parsing. Some metadata may be lost or altered, but the coordinate operations between two CRS should produce the same numerical results provided that the two CRS were formatted independently (do not rely on org.opengis.referencing.crs.GeneralDerivedCRS#getConversionFromBase() for instance).
• Instances of this class are not synchronized for multi-threading. It is recommended to create separated format instances for each thread. If multiple threads access a WKTFormat concurrently, it must be synchronized externally.
• Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS.
  [中]著名文本（WKT）字符串的解析器和格式化程序。这种格式处理一对解析器和格式化程序，分别由parse（…）和format（…）方法使用。WKTFormat对象允许进行以下配置：
  *要格式化的IdentifiedObject#getName（）的首选权限（有关更多信息，请参阅格式化程序#getNameAuthority（）。
  *要使用的符号（大括号或括号等）。
  *用于将Unicode字符替换为ASCII字符的音译器。
  *是否为ANSI X3。允许或不允许64种颜色（默认为不允许）。
  *压痕。
  字符串扩展由于此类要分析的字符串很长，并且往往包含重复的替换字符串，WKTFormat提供了一种在分析之前执行字符串替换的机制。长字符串可以通过调用#addFragment（String，String）方法来分配短名称。添加片段后，对解析方法的任何调用都将用名为“foo”的WKT片段替换所有出现的标记，如$foo（引号中的文本除外）。
  示例：在下面的示例中，在解析继续之前，在给定给parseObject（…）方法的参数中出现的$WGS84子字符串将扩展为完整的GeoMethodicRS[“WGS84”，…]字符串。#addFragment("deg", "AngleUnit[“degree”, 0.0174532925199433]"); #addFragment("lat", "Axis[“Latitude”, NORTH, $deg]"); #addFragment("lon", "Axis[“Longitude”, EAST, $deg]"); #addFragment("MyBaseCRS", "GeodeticCRS[“WGS84”, Datum[等...], CS[等...], $lat, $lon]"); Object crs = #parseObject(String)("ProjectedCRS[“Mercator_1SP”, $MyBaseCRS,等...]");注意，WKT片段的解析并不总是产生相同的对象。特别是，默认的线性和角度单位取决于WKT片段出现的上下文。
  局限性
  *WKT格式不是无损的！WKTFormat格式化的对象在解析后不保证完全相同。一些元数据可能会丢失或更改，但如果两个CR的格式是独立的（例如，不要依赖org.opengis.reference.CRS.GeneralDerivedCRS#getConversionFromBase（）），那么两个CR之间的坐标操作应该会产生相同的数值结果。
  *对于多线程，此类的实例不同步。建议为每个线程创建单独的格式实例。如果多个线程同时访问WKTFormat，则必须对其进行外部同步。
  *此类的序列化对象不保证与未来的Apache SIS版本兼容。序列化支持适用于运行同一版本Apache SIS的应用程序之间的短期存储或RMI。
