  • Method Details

    • isBuffer

      public boolean isBuffer()
      Description copied from interface: Buffer
      Returns whether this buffer represents a buffer or an event.
      Specified by:
      isBuffer in interface Buffer
      Returns:
      true if this is a real buffer, false if this is an event

    • getMemorySegment

      public org.apache.flink.core.memory.MemorySegment getMemorySegment()
      Description copied from interface: Buffer
      Returns the underlying memory segment. This method is dangerous since it ignores read only protections and omits slices. Use it only along the Buffer.getMemorySegmentOffset().

      This method will be removed in the future. For writing use BufferBuilder.

      Specified by:
      getMemorySegment in interface Buffer
      Returns:
      the memory segment backing this buffer

    • getMemorySegmentOffset

      public int getMemorySegmentOffset()
      Description copied from interface: Buffer
      This method will be removed in the future. For writing use BufferBuilder.
      Specified by:
      getMemorySegmentOffset in interface Buffer
      Returns:
      the offset where this (potential slice) Buffer's data start in the underlying memory segment.

    • getRecycler

      public BufferRecycler getRecycler()
      Description copied from interface: Buffer
      Gets the buffer's recycler.
      Specified by:
      getRecycler in interface Buffer
      Returns:
      buffer recycler

    • setRecycler

      public void setRecycler(BufferRecycler bufferRecycler)
      Description copied from interface: Buffer
      Sets the buffer's recycler.

      Note that updating the recycler is an unsafe operation and this method cannot guarantee thread safety. It is important for the caller to fully understand the consequences of calling this method. Incorrectly updating the buffer recycler can result in a leak of the buffer due to using a wrong recycler to recycle buffer. Therefore, be careful when calling this method.

      Specified by:
      setRecycler in interface Buffer
      Parameters:
      bufferRecycler - the new buffer recycler

    • recycleBuffer

      public void recycleBuffer()
      Description copied from interface: Buffer
      Releases this buffer once, i.e. reduces the reference count and recycles the buffer if the reference count reaches 0.
      Specified by:
      recycleBuffer in interface Buffer
      See Also:

    • isRecycled

      public boolean isRecycled()
      Description copied from interface: Buffer
      Returns whether this buffer has been recycled or not.
      Specified by:
      isRecycled in interface Buffer
      Returns:
      true if already recycled, false otherwise

    • retainBuffer

      public NetworkBuffer retainBuffer()
      Description copied from interface: Buffer
      Retains this buffer for further use, increasing the reference counter by 1.
      Specified by:
      retainBuffer in interface Buffer
      Returns:
      this instance (for chained calls)
      See Also:

    • readOnlySlice

      public ReadOnlySlicedNetworkBuffer readOnlySlice()
      Description copied from interface: Buffer
      Returns a read-only slice of this buffer's readable bytes, i.e. between Buffer.getReaderIndex() and Buffer.getSize().

      Reader and writer indices as well as markers are not shared. Reference counters are shared but the slice is not retained automatically.

      Specified by:
      readOnlySlice in interface Buffer
      Returns:
      a read-only sliced buffer

    • readOnlySlice

      public ReadOnlySlicedNetworkBuffer readOnlySlice(int index, int length)
      Description copied from interface: Buffer
      Returns a read-only slice of this buffer.

      Parameters:
      index - the index to start from
      length - the length of the slice
