◆ thr_lock_type

This class represents the character input stream consumed during lexical analysis.

In addition to consuming the input stream, this class performs some comment pre processing, by filtering out out-of-bound special text from the query input stream.

Two buffers, with pointers inside each, are maintained in parallel. The 'raw' buffer is the original query text, which may contain out-of-bound comments. The 'cpp' (for comments pre processor) is the pre-processed buffer that contains only the query text that should be seen once out-of-bound data is removed.
