Member Function Documentation

add_character()

virtual void Json_wrapper_hasher::add_character ( uchar  ch )

pure virtual

Implemented in Json_wrapper_crc_hasher, and Json_wrapper_xxh_hasher.

add_double()

void Json_wrapper_hasher::add_double ( double  d )

inline

add_integer()

void Json_wrapper_hasher::add_integer ( longlong  ll )

inline

add_string()

virtual void Json_wrapper_hasher::add_string ( const char *  str, size_t  len  )

pure virtual

Implemented in Json_wrapper_crc_hasher, and Json_wrapper_xxh_hasher.

get_hash_value()

virtual ulonglong Json_wrapper_hasher::get_hash_value ( )

inlinevirtual

Return the computed hash value in integer form.

This is optional as each seperate hasher would like to produce hash in different forms.

Reimplemented in Json_wrapper_crc_hasher.
