Member	Type	Description
in_text_source	`a_text_source *`	The pointer to the producer of the external term breaker (a_text_source object) to be created.
out_word_source	`a_word_source *`	The pointer to the external term breaker (a_word_source object) specified by the entry point function.
desired_charset	`const char *`	The character set the caller of the entry point function expects the output of the term breaker to be in. If is_binary flag is 0, this is also the character set the input to the term breaker will be in, unless negotiated otherwise.
actual_charset	`char *`	The character set (specified by the external library as part of negotiation) the external term breaker library will produce its output in. If is_binary is 0, this is also the actual character set of the input to the term breaker. Note that it is preferable that the library accept and produce the data in desired_charset, if possible.
term_breaker_for	`a_term_breaker_for`	The purpose for initializing the term breaker: TERM_BREAKER_FOR_LOAD Used for create, insert, update, and delete operations on the text index. Input may be prefiltered if a prefilter is specified. TERM_BREAKER_FOR_QUERY Used for parsing of query elements, stoplist, and input to the sa_char_term system procedure. In the case of TERM_BREAKER_FOR_QUERY, no prefiltering takes place, even if an external prefilter library is specified for the text index.

The a_init_term_breaker structure is defined by a header file named exttbapiv1.h, in the SDK\Include subdirectory of your SQL Anywhere installation directory.
