This file contains functions to read and manage recognition grammar. These function read in grammar and dictionary, and setup data for recognition.
Recognition with multiple grammars are supported. Julian can read several grammars specified at startup time, and perform recognition with those grammars simultaneously. In module mode, you can add / delete / activate / deactivate each grammar while performing recognition, and also can output optimum results for each grammar.
Internally, the given grammars are composed to a single Global Grammar. The global grammar will be updated whenever a new grammar has been read or deleted. The syntax rule (DFA) of the global grammar will be stored at global_dfa, and the corresponding dictionary will be at global_winfo locally, independent of the decoding timing. After that, multigram_build() will be called to make the prepared global grammar to be used in the actual recognition process, by copying the grammar and the dictionary to the global variable dfa and winfo.

| static boolean multigram_rebuild_wchmm | ( | RecogProcess * | r | ) | [static] |
Build tree lexicon from global grammar.
This function will re-construct the tree lexicon using the global grammar in the recognition process instance. If the beam width was not explicitly specified on startup, the the beam width will be guessed according to the size of the new lexicon.

| static boolean multigram_append_to_global | ( | DFA_INFO * | gdfa, | |
| WORD_INFO * | gwinfo, | |||

| ) | [static] |
Append a grammar to the tail of global grammar.
The location of the grammar in the global grammar (categories and words) will be stored to the grammar structure for later access.
