Interface ByteBuffersProvider

  • All Superinterfaces:
    io.netty.util.ReferenceCounted
    All Known Implementing Classes:
    InboundReadResponse, WriteRequest
    public interface ByteBuffersProvider
extends io.netty.util.ReferenceCounted
    This interface pulls out the two methods necessary to support the write.

    The reason for doing so is to avoid an additional buffer copy in translating a ThirdParty read request response into a write request.

      • logMetrics

        static void logMetrics​(java.lang.String when,
                       io.netty.buffer.ByteBufAllocator allocator,
                       org.slf4j.Logger logger,
                       java.lang.String level)
        For monitoring memory usage by Netty allocators. This method is best guarded by a conditional checking logger level activation.
        Parameters:
        when - info concerning the site of the call
        allocator - e.g., from the context
        logger - to use
        level - to log at (only supports "INFO", "DEBUG", "TRACE")

      • toByteBuffers

        java.nio.ByteBuffer[] toByteBuffers()
        Returns:
        NIO buffer array produced from the Netty ByteBuf.

      • getWriteOffset

        long getWriteOffset()
        Returns:
        the current offset to the buffer or channel receiving the written bytes.
