	Get the next "token" from the datasource of type datasource.
svn_error_t *(*	token_compare )(void *diff_baton, void *ltoken, void *rtoken, int *compare)
	A function for ordering the tokens, resembling 'strcmp' in functionality.

Field Documentation

svn_error_t*(* svn_diff_fns_t::datasource_open)(void *diff_baton, svn_diff_datasource_e datasource)

Open the datasource of type datasource.

svn_error_t*(* svn_diff_fns_t::datasource_close)(void *diff_baton, svn_diff_datasource_e datasource)

Close the datasource of type datasource.

svn_error_t*(* svn_diff_fns_t::datasource_get_next_token)(apr_uint32_t *hash, void **token, void *diff_baton, svn_diff_datasource_e datasource)

Get the next "token" from the datasource of type datasource.

Return a "token" in *token. Return a hash of "token" in *hash. Leave token and hash untouched when the datasource is exhausted.

svn_error_t*(* svn_diff_fns_t::token_compare)(void *diff_baton, void *ltoken, void *rtoken, int *compare)

A function for ordering the tokens, resembling 'strcmp' in functionality.

compare should contain the return value of the comparison: If ltoken and rtoken are "equal", return 0. If ltoken is "less than" rtoken, return a number < 0. If ltoken is "greater than" rtoken, return a number > 0.

void(* svn_diff_fns_t::token_discard)(void *diff_baton, void *token)

Free token from memory, the diff algorithm is done with it.

void(* svn_diff_fns_t::token_discard_all)(void *diff_baton)

Free *all* tokens from memory, they're no longer needed.
