类名称：XML

XML介绍

[英]Provides convenience methods for marshalling and unmarshalling SIS objects. Marshalling operations use the standard versions listed below (for marshalling a document in a different version, see MarshallerPool). Unmarshalling detects the version automatically. Versions of standards applied at marshalling timeTopicSIS 0.3 to 0.8SIS 1.0RemarksMetadataISO 19139:2007ISO 19115-3:2016ReferencingISO 19136:2007ISO 19136:2007Same as GML 3.2 This class defines also some property keys that can be given to the Marshallerand Unmarshaller instances created by MarshallerPool: Supported (un)marshaller propertiesKeyValue typePurpose#LOCALELocalefor specifying the locale to use for international strings and code lists.#TIMEZONETimeZonefor specifying the timezone to use for dates and times.#SCHEMASMapfor specifying the root URL of metadata schemas to use.#DEFAULT_NAMESPACEStringfor specifying the default namespace of the XML document to write.#GML_VERSIONVersionfor specifying the GML version of the document to be (un)marshalled.#METADATA_VERSIONVersionfor specifying the metadata version of the document to be (un)marshalled.#RESOLVERReferenceResolverfor replacing xlink or uuidref attributes by the actual object to use.#CONVERTERValueConverterfor controlling the conversion of URL, UUID, Units or similar objects.#STRING_SUBSTITUTESString[]for specifying which code lists to replace by simpler elements.#WARNING_LISTENERWarningListenerfor being notified about non-fatal warnings.
[中]为编组和解编组SIS对象提供了方便的方法。编组操作使用下面列出的标准版本（有关以不同版本编组文档，请参阅MarshallerPool）。解组自动检测版本。编组时间应用的标准版本为0.3到0.8SIS 1.0Remarks元数据ISO 19139:2007ISO 19115-3:2016ReferenceGiso 19136:2007ISO 19136:2007与GML 3.2相同，此类还定义了一些属性键，这些属性键可以提供给MarshallerPool:Supported（un）marshaller创建的marshaller和Unmarshaller实例Properties KeyValue typePurpose#LocaleCale用于指定用于国际字符串和代码列表的区域设置#TimeZoneTimeZone用于指定日期和时间的时区#SchemaMap用于指定要使用的元数据架构的根URL#DEFAULT_namespaceString用于指定要写入的XML文档的默认名称空间#GML_versionversion用于指定要（取消）封送的文档的GML版本#METADATA_versionVersion用于指定要（取消）封送的文档的元数据版本#ResolderReferenceResolver，用于将xlink或uuidref属性替换为要使用的实际对象#ConverterValueConverter用于控制URL、UUID、单位或类似对象的转换#STRING_substituteString[]用于指定哪些代码列表要替换为更简单的元素#警告\u Listener警告Listener收到非致命警告的通知。
