Series Of Expressions

Series of Expressions:

If you need to check some expressions in the series, you can use these types of indicators.

Expression Series:

This indicator retunes false by default. It checks expr1 and if it turns to true, it waits for expr2. If expr2 turns to true, it goes and checks expr3 and so on. As the last expr turns to true, the output will be true. Note that indicator waits for expression as long as all previous expressions are true. If one of the previous expressions becomes false, it goes and checks that expression.

Expression Machine:

This indicator retunes false by default. It checks expr1 and if it turns to true, it waits for expr2. If expr2 turns to true, it goes and checks expr3 and so on. As the last expr turns to true, the output will be true. Note that indicator waits for expression and as it starts for checking expression N, it doesn’t care to previous expressions. It is like a machine that waits for an expression to go to the next state. In the new state, it doesn’t care about previous steps. As the last state becomes true, it returns true and goes for the first expression again.
