What is the If{{expression}} else (Operator Brick)?
This Brick, designed for decision-making, helps determine actions based on specific conditions. For example, it directs what to do depending on whether data meets certain criteria, ensuring different paths or actions for different situations.
Use the branch at the bottom when the command matches if; otherwise, use the branch on the right when the command matches else.
If{{expression}} else Brick Parameters
-
Label: This is where the user can provide a name for the brick.
-
Expression: In
Vector Remap Language (VRL), define the value that needs matching with the data passing through this brick. If the match holds true, it follows one path; if not, it proceeds along a different path.-
Example
string!(%data.value) == "success"
`string!(%data.value)`: Converts `%data.value` into a string for comparison.
`== "success"`: Checks if the string representation of `%data.value` equals `"success"`.
In this example:
`%data.value` represents some variable or data attribute.
The expression checks if `%data.value` is equal to `"success"` after converting it into a string.
This can be used in conditional statements or expressions to control the flow of logic based on the value of `%data.value`.
