Expression Dependencies - Threshold Replacement

Overview

• We can a combination of an Expression and a Schedule Instance Property to function like a Threshold.
• Remember: Properties are Strings and NOT Integers

Usage

• It is necessary to convert a Property to Integer for an Expression to be true

Example

• We need to count something but don't want to use a Threshold
• We can use a Schedule Instance and a $PROPERTY:SET event to increment the SI value
  • SI: FILECOUNT with a Value of 0
  • Event: $PROPERTY:SET,SI.FILECOUNT,[[=ToInt([[SI.FILECOUNT]]) + 1]]
• This confines the count to this instance of the Schedule and doesn't require a reset at the end of the process
• We can then use ToInt([[SI.FILECOUNT]]) == N as an Expression Dependency
