0N/AContent types (complex) should create constant pool data
0N/Ain the recording.
0N/ACurrently at least, there is _NO_ verification that whatever
0N/Awriter you have is actually writing correctly. So BE CAREFUL!
0N/A
0N/ADeclared with the 'content_type' tag.
0N/A
0N/A<type> is the ID type, i.e the integer type that resolves this. Most often
0N/AU4 or U8, but for example really small number constants, like GCTYPE uses U1.
0N/A
0N/A<content-type> is where it gets interesting. 'builtin_type' means we're
0N/Adefining how we resolve one of the trace built-in types (Class, Thread etc),
0N/Ajvm_type means defining a new one for our own use.
0N/A
0N/AExample: (GcMode)
0N/A
0N/A<content_type id="GCMode" hr_name="GC mode" type="U1" jvm_type="GCMODE">
0N/A <value type="UTF8" field="desc" description="Description"/>
0N/A</content_type>
0N/A
0N/AThis creates a content type CONTENT_TYPE_GCMODE
0N/AThe field type referencing it is u1 (U1), and the constant pool struct has one field, the name.
0N/A
0N/ABefore we can use it we need also define a primary field data type:
0N/A
0N/A<primary_type symbol="GCMODE" datatype="U1" contenttype="NONE"
0N/A type="u8" sizeop="sizeof(u1)"/>
0N/A
0N/ANow we can use the content + data type in declaring event fields.
0N/ARemember however, that for us to be able to resolve the value later we must also add
0N/Acreating the constant pool data in VM_JFRCheckpoint::write_checkpoint
0N/A
0N/A ...
0N/A //CGMODE
0N/A w->be_uint(CONTENT_TYPE_GCMODE);
0N/A w->be_uint(MM_GC_MODE_UNINITIALIZED);
0N/A for (i = 0; i < MM_GC_MODE_UNINITIALIZED; i++) {
0N/A w->uchar(i);
0N/A w->write_utf8(gcModeGetName(i));
0N/A }
