| 29 Content types (complex) should create constant pool data | |
| 30 in the recording. | |
| 31 Currently at least, there is _NO_ verification that whatever | |
| 32 writer you have is actually writing correctly. So BE CAREFUL! | |
| 33 | |
| 34 Declared with the 'content_type' tag. | |
| 35 | |
| 36 <type> is the ID type, i.e the integer type that resolves this. Most often | |
| 37 U4 or U8, but for example really small number constants, like GCTYPE uses U1. | |
| 38 | |
| 39 <content-type> is where it gets interesting. 'builtin_type' means we're | |
| 40 defining how we resolve one of the trace built-in types (Class, Thread etc), | |
| 41 jvm_type means defining a new one for our own use. | |
| 42 | |
| 43 Example: (GcMode) | |
| 44 | |
| 45 <content_type id="GCMode" hr_name="GC mode" type="U1" jvm_type="GCMODE"> | |
| 46 <value type="UTF8" field="desc" description="Description"/> | |
| 47 </content_type> | |
| 48 | |
| 49 This creates a content type CONTENT_TYPE_GCMODE | |
| 50 The field type referencing it is u1 (U1), and the constant pool struct has one field, the name. | |
| 51 | |
| 52 Before we can use it we need also define a primary field data type: | |
| 53 | |
| 54 <primary_type symbol="GCMODE" datatype="U1" contenttype="NONE" | |
| 55 type="u8" sizeop="sizeof(u1)"/> | |
| 56 | |
| 57 Now we can use the content + data type in declaring event fields. | |
