java.nio.ByteBuffer related utilities.

Buffer, FixedBuffer and AutoBuffer

• Buffer a buffer inspired from java.nio.ByteBuffer.
  • FixedBuffer: a buffer with fixed size.
  • AutoBuffer: a buffer grows when required.
  • Buffers: factory methods for Buffer.

FixedBuffer

FixedBuffer is an abstraction similar to java.nio.ByteBuffer. Refer to FixedBuffer to find out details.

AutoBuffer

There are 3 types of auto buffer:

• Arithmetic Progression (AP): grows following AP sequences, with initial capacity and difference.
  • Factory method: Buffers.apAutoBuffer(Allocator allocator, int initCapacity, int difference)
• Geometric Progression (GP): grows following GP sequences, with initial capacity and ratio.
  • Factory method: Buffers.gpAutoBuffer(Allocator allocator, int initCapacity, double ratio)
• Power of 2 (POW2): grows with double capacity.
  • Factory method: Buffers.pow2AutoBuffer(Allocator allocator, int initCapacity)

Allocator

• Allocator allocator for Buffer.
  • FixedBufferAllocator: allocator for FixedBufferAllocator.
• Allocators: factory methods for Allocator.
  • Allocator from pool: Allocators.fromPool(IntFunction<FixedBufferPool> poolFactory)

Pool

• Pool pool for Buffer.
  • FixedBufferPool pool for FixedBufferAllocator.
• Pools factory methods for Pool.
  • Pool from allocator:
    • Pools.fromAllocator(FixedBufferAllocator allocator, int bufferCapacity)
    • Pools.fromAllocator(FixedBufferAllocator allocator, int bufferCapacity, int initSize)
