[英]Java Flight Recorder: Recording data as a byte array
Recording
allows to save recorded data into file using dump()
method (as shown in example below copied from the javadoc). Recording
允许使用dump()
方法将记录的数据保存到文件中dump()
如下面从 javadoc 复制的示例所示)。 Is there a way how to get such recorded data in form of byte[]
.有没有办法以byte[]
形式获取这样的记录数据。
Preferably without external dependencies.最好没有外部依赖。 I'm aware of implementing custom in-memory FileSystem
.我知道实现自定义内存中FileSystem
。
Configuration c = Configuration.getConfiguration("default");
Recording r = new Recording(c);
r.start();
System.gc();
Thread.sleep(5000);
r.stop();
r.dump(Files.createTempFile("my-recording", ".jfr"));
Are you looking for getStream
?您在寻找getStream
吗? That's the only API on Recording
that might possibly suggest a way to do it.这是Recording
上唯一可能建议一种方法的 API。 Other than that, you'll pretty much have to use dump
to a Path
, either to an in-memory filesystem or maybe even to an actual temporary file.除此之外,您几乎必须使用dump
到Path
,或者到内存文件系统,或者甚至到实际的临时文件。
