Code Style

• Indent code with TAB having width of 4 characters
• Code line width: 100 characters
• Long line example:

nextSubTask = new BasicPartialMutableDataIoTask<>(
    ioType, nextPart, srcPath, dstPath, equalPartsCount, this
);

• If something may be declared as final it should be declared as final
• The sole class implementing the interface X usually has a name BasicX
• Take care about the performance:
  • Avoid frequent objects instantiation
  • Avoid unnecessary frequent allocation
  • Avoid I/O threads blocking
  • Use thread locals (encryption, string builders)
