UTF8 Store

UTF8 Store documentation; version 1.0

UTF8 Store is a free script that converts any numbers, dates, strings and special values into one Unicode string and reads the values back.

write all values (int / float / date / string / error) => UTF8Store (single string) => read any single or more values (int / float / date / string / error)

Basic description

UTF8 Store is a script that converts any numbers, dates, strings and special values into one Unicode string.
The values storage is optimized to be as short as possible when the Unicode string is saved in UTF8 encoding.
The generated string contains only safe Unicode JavaScript string characters (also without double quotes and backslash).

Storage type is specified by 32bit integer called "ucode" that is passed to every read and write function.
The ucode must be the same for the value write and read.
There are many ucode options for various value types and ranges.

The UTF8 Store string contains only the stored values; to read the value you have to know its ucode type and its position in the UTF8 Store string.
The UTF8 Store is designed to save values of tables, where column value types (ucode) and their positions are the same for every row that is saved to the UTF8 Store.

Main advantages

Any value from the UTF8 Store string can be read directly and very fast without any parsing or decompressing other values or the whole UTF8 Store string.

The UTF8 Store string allocates remarkably less memory (many times less) than any array of the stored numbers, dates or strings.

The UTF8 Store string can be sent raw from server to client or back without any changes. It is shorter than any other format and can be also effectivelly zip compressed by server.

Basic usage

1) Find ucodesAnalyze your table data and find the best ucodes for individual columns.
Optionally use FindUCode method to find the best ucodes from data automatically.
2) Find positionsCalculate the column value positions (in characters) in the UTF8 Store string.
Optionally use GetUCodeSize method to get number of characters the individual ucode data allocates in the UTF8 Store string.
3) Write valuesCode all cells from rows from your table data to UTF8 Store string by WriteValue or WriteValues methods.
4) Transfer stringOptionally send the UTF8 Store string from server to client or vice versa or do any other string transfer.
5) Read value(s)Read any value from the UTF8 Store string by ReadValue or ReadValues methods. Use appropriate ucode and position as (row_position * row_size + column_position).

License

UTF8 Store is part of FastGrid development, but can be used also separately without FastGrid in any project.

Using UTF8 Store is free of charge, but the UTF8 Store script source codes must not be modified.
