KLBuffer

Fast write/read Buffer in javascript way.

How to use

• uchar array

  let klBuffer = KLBuffer.alloc(2);
  console.log(klBuffer.ucharArray); //[0,0]
  klBuffer.ucharArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
  console.log(klBuffer.ucharArray); //[1,2,3,4,5,6,7,8,9,10]
  console.log(klBuffer.uchar[5]); //6
  klBuffer.uchar[5] = 50;
  console.log(klBuffer.uchar[5]); //50

• double array

  let klBuffer = KLBuffer.alloc(16);
  console.log(klBuffer.doubleArray); //[0,0]
  klBuffer.doubleArray = [1.5, 2.5];
  console.log(klBuffer.doubleArray); //[1.5,2.5]
  console.log(klBuffer.double[0]);  //1.5
  klBuffer.double[0] = 3.5;
  console.log(klBuffer.double[0]);  //3.5

• copy data from pointer

  let klBuffer1 = KLBuffer.alloc(10);
  let klBuffer2 = KLBuffer.alloc(10);
  klBuffer1.ucharArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
  console.log(klBuffer2.ucharArray); //[0,0,0,0,0,0,0,0,0,0]
  klBuffer2.from(klBuffer1.ptr);
  console.log(klBuffer2.ucharArray); //[1,2,3,4,5,6,7,8,9,10]

• initialization buffer width pointer

  let klBuffer1 = KLBuffer.alloc(10);
  klBuffer1.ucharArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
  let klBuffer2 = KLBuffer.alloc(5, klBuffer1.ucharPtr[5]);
  console.log(klBuffer2.ucharArray); //[6,7,8,9,10]

• The difference between deepCopy being true and false

  let klBuffer1 = KLBuffer.alloc(10);
  klBuffer1.ucharArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
  let klBuffer2 = KLBuffer.alloc(5, klBuffer1.ucharPtr[5], true);
  klBuffer2.ucharArray = [1,2,3,4,5];
  console.log(klBuffer1.ucharArray); //[1,2,3,4,5,6,7,8,9,10]

  let klBuffer3 = KLBuffer.alloc(5, klBuffer1.ucharPtr[5], false);
  klBuffer3.ucharArray = [1,2,3,4,5];
  console.log(klBuffer1.ucharArray); //[1,2,3,4,5,1,2,3,4,5]

  console.log(klBuffer1.ptrVal, klBuffer2.ptrVal, klBuffer3.ptrVal);
