### Question:
NetworkBuffer extends AbstractReferenceCountedByteBuf implements Buffer { @Override public boolean isBuffer() { return isBuffer; } NetworkBuffer(MemorySegment memorySegment, BufferRecycler recycler);  NetworkBuffer(MemorySegment memorySegment, BufferRecycler recycler, boolean isBuffer);  NetworkBuffer(MemorySegment memorySegment, BufferRecycler recycler, boolean isBuffer, int size); @Override boolean isBuffer(); @Override void tagAsEvent(); @Override MemorySegment getMemorySegment(); @Override int getMemorySegmentOffset(); @Override BufferRecycler getRecycler(); @Override void recycleBuffer(); @Override boolean isRecycled(); @Override NetworkBuffer retainBuffer(); @Override ReadOnlySlicedNetworkBuffer readOnlySlice(); @Override ReadOnlySlicedNetworkBuffer readOnlySlice(int index, int length); @Override int capacity(); @Override int getMaxCapacity(); @Override int getReaderIndex(); @Override void setReaderIndex(int readerIndex); @Override int getSize(); @Override void setSize(int writerIndex); @Override ByteBuf capacity(int newCapacity); @Override ByteOrder order(); @Override ByteBuf unwrap(); @Override boolean isDirect(); @Override ByteBuf getBytes(int index, ByteBuf dst, int dstIndex, int length); @Override ByteBuf getBytes(int index, byte[] dst, int dstIndex, int length); @Override ByteBuf getBytes(int index, ByteBuffer dst); @Override ByteBuf getBytes(int index, OutputStream out, int length); @Override int getBytes(int index, GatheringByteChannel out, int length); @Override int getBytes(int index, FileChannel out, long position, int length); @Override ByteBuf setBytes(int index, ByteBuf src, int srcIndex, int length); @Override ByteBuf setBytes(int index, byte[] src, int srcIndex, int length); @Override ByteBuf setBytes(int index, ByteBuffer src); @Override int setBytes(int index, InputStream in, int length); @Override int setBytes(int index, ScatteringByteChannel in, int length); @Override int setBytes(int index, FileChannel in, long position, int length); @Override ByteBufAllocator alloc(); @Override void setAllocator(ByteBufAllocator allocator); @Override ByteBuf copy(int index, int length); @Override ByteBuf readBytes(int length); @Override int nioBufferCount(); @Override ByteBuffer getNioBufferReadable(); @Override ByteBuffer getNioBuffer(int index, int length); @Override ByteBuffer nioBuffer(int index, int length); @Override ByteBuffer internalNioBuffer(int index, int length); @Override ByteBuffer[] nioBuffers(int index, int length); @Override boolean hasArray(); @Override byte[] array(); @Override int arrayOffset(); @Override boolean hasMemoryAddress(); @Override long memoryAddress(); @Override String toString(); @Override ByteBuf asByteBuf();  }### Answer:
@Test public void testDataBufferIsBuffer() { assertFalse(newBuffer(1024, 1024, false).isBuffer()); }
@Test public void testEventBufferIsBuffer() { assertFalse(newBuffer(1024, 1024, false).isBuffer()); }
