Field Documentation

datasource_get_next_token

svn_error_t*(* svn_diff_fns2_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.

token_compare

svn_error_t*(* svn_diff_fns2_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.
