<!--
!
! Content types (complex) should create constant pool data
! in the recording.
Currently at least, there is _NO_ verification that whatever
writer you have is actually writing correctly. So BE CAREFUL!
-
Declared with the 'content_type' tag.
!
! <type> is the ID type, i.e the integer type that resolves this. Most often
! U4 or U8, but for example really small number constants, like GCTYPE uses U1.
!
<content-type> is where it gets interesting. 'builtin_type' means we're
defining how we resolve one of the trace built-in types (Class, Thread etc),
jvm_type means defining a new one for our own use.
-
Example: (GcMode)
!
! <content_type id="GCMode" hr_name="GC mode" type="U1" jvm_type="GCMODE">
! <value type="STRING" field="desc" description="Description"/>
</content_type>
-
This creates a content type CONTENT_TYPE_GCMODE
! The field type referencing it is u1 (U1), and the constant pool struct has one field, the name.
!
Before we can use it we need also define a primary field data type:
!
! <primary_type symbol="GCMODE" datatype="U1" contenttype="NONE"
! type="u8" sizeop="sizeof(u1)"/>
!
Now we can use the content + data type in declaring event fields.
