public boolean isContiguous()

Overrides io.netty.buffer.ByteBuf.isContiguous.

Doc from io.netty.buffer.ByteBuf.isContiguous.

Returns true if this ByteBuf implementation is backed by a single memory region. Composite buffer implementations must return false even if they currently hold ≤ 1 components. For buffers that return true, it's guaranteed that a successful call to discardReadBytes() will increase the value of maxFastWritableBytes() by the current readerIndex.

This method will return false by default, and a false return value does not necessarily mean that the implementation is composite or that it is not backed by a single memory region.

public ByteBuffer nioBuffer(int index, int length)

Implements abstract io.netty.buffer.ByteBuf.nioBuffer.

Doc from io.netty.buffer.ByteBuf.nioBuffer.

Exposes this buffer's sub-region as an NIO ByteBuffer. The returned buffer either share or contains the copied content of this buffer, while changing the position and limit of the returned NIO buffer does not affect the indexes and marks of this buffer. This method does not modify readerIndex or writerIndex of this buffer. Please note that the returned NIO buffer will not see the changes of this buffer if this buffer is a dynamic buffer and it adjusted its capacity.

Returns the reference count of this object. If 0, it means this object has been deallocated.
