Token array.
Token array is an array of bytes to store tokens received during parsing. Following is the way token array is formed. ... <non-id-token> <non-id-token> <id-token> <id_len> <id_text> ... For Example: SELECT * FROM T1; <SELECT_TOKEN> <*> <FROM_TOKEN> <ID_TOKEN> <2> <T1>
m_byte_count
bytes are initialized, out of m_token_array_length
