Threshold
apama.analyticskit.blocks.core.Threshold
Compares the input value against the defined threshold value to detect whether the input breaches the threshold or whether it crosses the threshold.
A breach occurs when the direction has been set to 'Above' and the input value is greater than the defined threshold value, or when the direction has been set to 'Below' and the input value is less than the defined threshold, or when the direction has been set to 'Above or Equal' and the input value is greater than or equal to the defined threshold value, or when the direction has been set to 'Below or Equal' and the input value is less than or equal to the defined threshold value.
A pulse is sent when the defined threshold value is crossed from any direction.
