    public class AnalogFanCompressor
extends java.lang.Object
implements ValueCompressor
    This compressor implements the SLIM1 algorithm.

    • Constructor Detail

      • AnalogFanCompressor

        public AnalogFanCompressor​(double tolerance,
                           DataType dType)

    • Method Detail

      • setTolerance

        public void setTolerance​(double val)

      • resetStats

        protected void resetStats()

      • putValue

        public java.util.List<QualifiedValue> putValue​(QualifiedValue inValue)
        Description copied from interface: ValueCompressor
        Places a value into the compressor to be processed. Any available processed values are returned. Will return an empty list if no values should be emitted (will not return null).

        Important: For performance reasons, the list returned may be the same object between calls. Therefore, it should not be held onto. The values should be utilized directly after calling this function.

      • slope

        protected float slope​(double newValue,
                      long newTime)

      • flush

        public java.util.List<QualifiedValue> flush()
        Description copied from interface: ValueCompressor
        Tells the compressor to return any values it can. Can be used before shutdown, or when the max-age has been reached in order to force values to be written.

        Important: For performance reasons, the list returned may be the same object between calls. Therefore, it should not be held onto. The values should be utilized directly after calling this function.
