Make use of DSL Grammar
Using DSL grammar, you can combine different behaviours in intuitive ways to bring out a functionality while creating custom profiler rules.
The two dummy behaviours available in this framework are as follows:
falseIdentity- Always evaluates to false, regardless of the input.trueIdentity- Always evaluates to true, regardless of the input.
These two behaviors are used in the following examples and descriptions.
Binary AND operator
Keyword: and
And works the same way it does it other languages. Hence following observations.
falseIdentity and trueIdentity == falseIdentityfalseIdentity and falseIdentity == falseIdentitytrueIdentity and trueIdentity == trueIdentitytrueIdentity and falseIdentity == falseIdentityHere we are using == to show their equality.
Binary OR operator
The or operator works the same way it does it other languages.
falseIdentity or trueIdentity == trueIdentityfalseIdentity or falseIdentity == falseIdentitytrueIdentity or trueIdentity == trueIdentitytrueIdentity or falseIdentity == trueIdentityLet's expand our DSL to use or as follows.
val rule1= falseIdentity and trueIdentity and trueIdentityval rule2= trueIdentity and trueIdentity and trueIdentityval rule3=rule1 and rule2rule3 or trueIdentityThe above expression evaluates to true.
