Script language implementations in UTF8 Store

UTF8 Store documentation; version 1.0

JavaScript

Defined in file UTF8Store.js.
All functions are static methods of global object UTF8Store.
If loaded FastGrid (FGridE.js), all the functions are also static methods of global object FGrid.
The implementation is shared with FastGrid, but they are independent.
JavaScript samples

Basic: var U1 = UTF8Store.WriteValue(123,0x1), o1 = UTF8Store.ReadValue(U1,0x1); console.log("'"+U1+"': "+o1);
Texts: var texts = [], U2 = UTF8Store.WriteValue("abcd",0x3,0,texts), o2 = UTF8Store.ReadValue(U2,0x3,0,texts); console.log("'"+U2+"' ["+texts+"]: "+o2);
Bits: var ucodes = [0xB,0x8,0xB,0xC,0xD,0x9], U3 = UTF8Store.WriteValues([1,100,0,3,7,50],ucodes), O3 = UTF8Store.ReadValues(U3,ucodes); console.log("'"+U3+"': "+O3);
Date: var ucode4 = UTF8Store.AddToUCode(0x14,new Date("1/1/2020")), U4 = UTF8Store.WriteValue(new Date("12/21/2020 12:34:56"),ucode4), o4 = UTF8Store.ReadValue(U4,ucode4); console.log("'"+U4+"': "+o4);
Float: var ucode5 = UTF8Store.GetUCode(2,1,4), U5 = UTF8Store.WriteValue(-12345.6789,ucode5), o5 = UTF8Store.ReadValue(U5,ucode5); console.log("'"+U5+"': "+o5);

C#

Non-nullable defaults implementation for C# 8+ is defined in file UTF8Store.cs.
Backward compatible nullable implementation for C# 7- is defined in UTF8Store7.cs.
All functions are static methods of UTF8Store static class.
There is defined value type struct UTF8Store.Value as universal value containing integer, double, string or date time. The UTF8Store functions use the UTF8Store.Value type by default, especially for returning values.
The UTF8Store functions accept also universal object with primitive type, string or DateTime as value to store.
There is defined reference type class UTF8Store.Strings to create updatable array of unique strings with indexes and also sortable by count of Add() access. Used for filling texts and utexts.
C# samples

Basic: string U1 = UTF8Store.WriteValue(123,0x1); int o1 = UTF8Store.ReadValue(U1,0x1); Console.WriteLine("'"+U1+"': "+o1);
Texts: UTF8Store.Strings texts = new UTF8Store.Strings(); string U2 = UTF8Store.WriteValue("abcd",0x3,0,texts); string o2 = UTF8Store.ReadValue(U2,0x3,0,texts); Console.WriteLine("'"+U2+"' ["+texts+"]: "+o2);
Bits: int[] ucodes = new int[]{0xB,0x8,0xB,0xC,0xD,0x9}; string U3 = UTF8Store.WriteValues(new UTF8Store.Value[]{1,100,0,3,7,50},ucodes); UTF8Store.Value[] O3 = UTF8Store.ReadValues(U3,ucodes); Console.WriteLine("'"+U3+"': "+UTF8Store.Value.Join(",",O3));
Date: int ucode4 = UTF8Store.AddToUCode(0x14,new DateTime(2020,1,1)); string U4 = UTF8Store.WriteValue(new DateTime(2020,12,21,12,34,56),ucode4); DateTime o4 = UTF8Store.ReadValue(U4,ucode4); Console.WriteLine("'"+U4+"': "+o4);
Float: int ucode5 = UTF8Store.GetUCode(2,1,4); string U5 = UTF8Store.WriteValue(-12345.6789,ucode5); double o5 = UTF8Store.ReadValue(U5,ucode5); Console.WriteLine("'"+U5+"': "+o5);

JAVA

Defined in file UTF8Store.java or UTF8Store.jsp
All functions are static methods of UTF8Store static class.
All the UTF8Store functions accept and return universal object with primitive type, string or LocalDateTime.
There is defined type class UTF8Store.Strings to create updatable array of unique strings with indexes and also sortable by count of add() access. Used for filling texts and utexts.
JAVA samples

Basic: String U1 = UTF8Store.WriteValue(123,0x1); int o1 = UTF8Store.ReadInt(U1,0x1); System.out.println("'"+U1+"': "+o1);
Texts: UTF8Store.Strings texts = new UTF8Store.Strings(); String U2 = UTF8Store.WriteValue("abcd",0x3,0,texts); String o2 = UTF8Store.ReadString(U2,0x3,0,texts); System.out.println("'"+U2+"' ["+texts+"]: "+o2);
Bits: int[] ucodes = new int[]{0xB,0x8,0xB,0xC,0xD,0x9}; String U3 = UTF8Store.WriteValues(new Object[]{1,100,0,3,7,50},ucodes); Object[] O3 = UTF8Store.ReadValues(U3,ucodes); System.out.println("'"+U3+"': "+UTF8Store.Join(",",O3));
Date: int ucode4 = UTF8Store.AddToUCode(0x14,LocalDate.of(2020,1,1)); String U4 = UTF8Store.WriteValue(LocalDateTime.of(2020,12,21,12,34,56),ucode4); LocalDateTime o4 = UTF8Store.ReadDateTime(U4,ucode4); System.out.println("'"+U4+"': "+o4);
Float: int ucode5 = UTF8Store.GetUCode(2,1,4); String U5 = UTF8Store.WriteValue(-12345.6789,ucode5); double o5 = UTF8Store.ReadDouble(U5,ucode5); System.out.println("'"+U5+"': "+o5);

PHP

Defined in file UTF8Store.php.
All functions are static methods of class UTF8Store.
There is defined class UTF8Strings to create updatable array of unique strings with indexes and also sortable by count of add() access. Used for filling texts and utexts.
PHP samples

Bits: $ucodes = [0xB,0x8,0xB,0xC,0xD,0x9]; $U3 = UTF8Store::WriteValues([1,100,0,3,7,50],$ucodes); $O3 = UTF8Store::ReadValues($U3,$ucodes); echo "'$U3': ".join(",",$O3)."\n";
