Blackfeather.Data.ManagedMemory

Ths is a helper class for storing data in memory in JavaScript. It supports serialization between languages allowing you to import, and, export serializable types.

ManagedMemorySpace

Model that data in memory is read, and, written too.

  Blackfeather.Data.ManagedMemorySpace = function (pointer, name, value, created, accessed, updated) {
    this.Created = created; // unix time
    this.Accessed = accessed; // unix time
    this.Updated = updated; // unix time
    this.Pointer = pointer; // string
    this.Name = name; // string
    this.Value = value; // any
  };

Read(ponter:string, name:string):ManagedMemorySpace

Read entry from memory that matches the pointer, and, name.

  var memory = new Blackfeather.Data.ManagedMemory();
  var caw = memory.Read("birds", "raven");
  console.log(caw);

ReadAll(ponter:string):[ManagedMemorySpace]

Read all entries from memory that matches the pointer.

  var memory = new Blackfeather.Data.ManagedMemory();
  var birds = memory.ReadAll("birds");
  console.log(birds);

Write(ponter:string, name:string, value:any):void

Write entry into memory. Remove any previous entry that matches the pointer, and, name.

  var memory = new Blackfeather.Data.ManagedMemory();
  memory.Write("birds", "raven", "caw");

WriteAll(spaces:[ManagedMemorySpace]):void

Write all entres into memory. Remove any previous entries that matches the pointer, and, name.

  var memory = new Blackfeather.Data.ManagedMemory();
  var spaces = [new Blackfeather.Data.ManagedMemorySpace("birds", "raven", "caw", 0, 0, 0)];
  
  memory.WriteAll(spaces);

Delete(ponter:string, name:string):void

Remove any entry from memory that matches the pointer, and, name.

  var memory = new Blackfeather.Data.ManagedMemory();
  memory.Delete("birds", "raven");

DeleteAll(ponter:string):void

Remove all entries from memory that matches the pointer.

  var memory = new Blackfeather.Data.ManagedMemory();
  memory.DeleteAll("birds");

Import(memory:ManagedMemory):void

Load ManagedMemory class as current MangedMemory class.

  var memory = new Blackfeather.Data.ManagedMemory();
  var memory2 = new Blackfeather.Data.ManagedMemory();
  memory.Import(memory2);

Export():ManagedMemory

Return current ManagedMemory class.

  var memory = new Blackfeather.Data.ManagedMemory();
  var memory2 = memory.Export();

Clear():void

Remove all entries from memory. Leaves memory still usable.

  var memory = new Blackfeather.Data.ManagedMemory();
  memory.Clear();

Dispose():void

Remove all entries from memory. Leaves memory unusable until reconstructed.

  var memory = new Blackfeather.Data.ManagedMemory();
  memory.Dispose();

Blackfeather.Data.Compression

This is a collection of usable compression libraries in JavaScript. Right now only LZStrng is supported.

LZString

Compress(data:string):string

  var compressed = Blackfeather.Data.Compression.LZString.Compress("caw caw caw!");
  console.log(compressed);

Decompress(data:string):string

  var decompressed = Blackfeather.Data.Compression.LZString.Decompress(
    Blackfeather.Data.Compression.LZString.Compress("caw caw caw!")
  );
  console.log(compressed);

Blackfeather.Data.Encoding

extEncoding

  Latin1
  Utf8
  Utf16
  Utf16BigEndian
  Utf16LittleEndian

BinaryEncoding

  Blackfeather.Security.Cryptology.SaltedData = function () {
    this.Data = null;

  }

Blackfeather.Security.Cryptology.SecureRandom

NextBytes(length:number):string

Returns random bytes to the specified length.

  var rng = new Blackfeather.Security.Cryptology.SecureRandom().NextBytes(16);
  console.log(rng);

NextBigInt(length:number):string

Returns random bytes to the specified length.

  var rng = new Blackfeather.Security.Cryptology.SecureRandom().NextBigInt(2048);
  console.log(rng);
