| /* |
| * KlassFactory is an interface to implementations of the following mapping/function: |
| * |
| * Summary: create a VM internal runtime representation ("Klass") |
| from a bytestream (classfile). |
| * |
| * Input: a named bytestream in the Java class file format (see JVMS, chapter 4). |
| * Output: a VM runtime representation of a Java class |
| * |
| * Pre-conditions: |
| * a non-NULL ClassFileStream* // the classfile bytestream |
| * a non-NULL Symbol* // the name of the class |
| * a non-NULL ClassLoaderData* // the metaspace allocator |
| * (no pending exceptions) |
| * |
| * Returns: |
| * if the returned value is non-NULL, that value is an indirection (pointer/handle) |
| * to a Klass. The caller will not have a pending exception. |
| * |
| * On broken invariants and/or runtime errors the returned value will be |
| * NULL (or a NULL handle) and the caller *might* now have a pending exception. |
