Instance members

• var capacity: Int

  The current capacity of the storage of this ByteBuffer, this is not constant and does not signify the number of bytes that have been written to this ByteBuffer.

• var debugDescription: String

  A String describing this ByteBuffer with some portion of the readable bytes dumped too. Example:

• var description: String

  A String describing this ByteBuffer. Example:

• var readableBytes: Int

  The number of bytes readable (readableBytes = writerIndex - readerIndex).

• var readableBytesView: ByteBufferView

  A view into the readable bytes of the ByteBuffer.

• var readerIndex: Int

  The reader index or the number of bytes previously read from this ByteBuffer. readerIndex is 0 for a newly allocated ByteBuffer.

  The current capacity of the underlying storage of this ByteBuffer. A COW slice of the buffer (e.g. readSlice(length: x)) will posses the same storageCapacity as the original buffer until new data is written.

• var writableBytes: Int

  The number of bytes writable until ByteBuffer will need to grow its underlying storage which will likely trigger a copy of the bytes.
