    • Method Detail

      • 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:
        Buffer.retainBuffer()

      • 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:
        Buffer.recycleBuffer()

      • readOnlySlice

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

        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
        Parameters:
        index - the index to start from
        length - the length of the slice
        Returns:
        a read-only sliced buffer
