Class ByteBlockPool

The first level size for new slices

An array holding the level sizes for byte slices.

An array holding the offset into the LEVEL_SIZE_ARRAY to quickly navigate to the next slice level.

Current head buffer

Array of buffers currently used in the pool. Buffers are allocated if needed don't modify this outside of this class.

Current head offset

Where we are in head buffer

Creates a new byte slice with the given starting size and returns the slices offset in the pool.

Appends the bytes in the provided BytesRef at the current position.

Allocates a new slice with the given size.

Advances the pool to its next buffer. This method should be called once after the constructor to initialize the pool. In contrast to the constructor a Reset() call will advance the pool to its first buffer immediately.

Reads bytes bytes out of the pool starting at the given offset with the given length into the given byte array at offset off.

Note: this method allows to copy across block boundaries.

Resets the pool to its initial state reusing the first buffer and fills all buffers with 0 bytes before they reused or passed to RecycleByteBlocks(Byte[][], Int32, Int32). Calling NextBuffer() is not needed after reset.

Expert: Resets the pool to its initial state reusing the first buffer. Calling NextBuffer() is not needed after reset.
