Constructor Details

DataCompressor

public DataCompressor(int size)

There are 3 ways to write primitves:

Direct Unsafe Bytes

byte[] bytes = new byte[4]; UNSAFE.putIntUnaligned(bytes, ARRAY_BASE_OFFSET, i, true); SCOPED_MEMORY_ACCESS.putIntUnaligned(null, bytes, 0, i, true);

ByteBuffer

Using ByteBuffer.putInt(int), etc...

ByteArray Util

The class jdk.internal.util.ByteArray, is used by DataOutputStream, however since it's an internal JDK class, we cannot use it directly. The only bad thing about this is the fact that there is an internal counter inside DataOutputStream which is unnecessary for our case.

Bitwise Operatons

Direct bitwise operations are also possible which is what older versions of Java such as JDK 7 used.
