[英]How to serialize UIMA CAS combined with Java Serialization
I have these classes: 我有这些课:
class DocumentObj implements Serializable {
...
List<SentenceObj> sentenceObjs;
JCas docJcas;
}
class SentenceObj implements Serializable {
...
annotation.Sentence sentenceAnnotation;
}
I would like to dump each DocumentObj as a file on disk, using the default Java serialization. 我想使用默认的Java序列化将每个DocumentObj转储为磁盘上的文件。 Later they would also be deserialized back into the Java objects. 以后,它们也将反序列化回Java对象。 I understand I would need some special treatment for the JCases and the Sentence Annotations as they are not serializable (now I get NotSerializableException
). 我知道我需要对JCases和Sentence Annotations进行一些特殊处理,因为它们无法序列化(现在我得到NotSerializableException
)。 Hopefully the treatment could be as minimal as possible. 希望治疗可以尽可能少。
How do you suggest to do this, regarding serialization of JCas and combining it with Java serialization? 关于JCas的序列化并将其与Java序列化相结合,您如何建议这样做?
I am working on Windows, with Java 1.6 and UIMA 2.4.0. 我正在使用Java 1.6和UIMA 2.4.0的Windows上工作。 I am using the same type system and the same 3 views for all JCases and annotations. 我对所有JCases和注释使用相同的类型系统和相同的3个视图。
Don't use default Java serialization. 不要使用默认的Java序列化。 Use instead the org.apache.uima.cas.impl.Serialization
utilities, or even better the BinaryCasWriter from DK-pro. 改用org.apache.uima.cas.impl.Serialization
实用程序,或者甚至更好地使用DK-pro的BinaryCasWriter 。
