Constructor Detail

Threshold

public Threshold(java.util.Map<java.lang.String,java.lang.String> query)

Constructs a threshold config object from a URI string

Parameters:

query - String-String map containing the fields from the URI string

Threshold

public Threshold(java.lang.Number limit,
         Threshold.OutputMode mode,
         java.lang.Number hysteresis)

Constructs a threshold config object, setting the hysteresis distance

Parameters:

limit - Boundary the data must cross

mode - Operation mode for the processor

hysteresis - Minimum distance between the limit and value to signal a successful crossing. Use with data that may frequently oscillate around the threshold limit.

Threshold

public Threshold(java.lang.Number limit,
         Threshold.OutputMode mode)

Constructs a threshold config object

Parameters:

limit - Boundary the data must cross

mode - Operation mode for the processor
