fun match(vararg expressions: Expression): Expression

Selects the output whose label value matches the input value, or the fallback value if no match is found. The input can be any expression (e.g. ["get", "building_type"]). Each label must be either:

  • a single literal value; or

  • an array of literal values, whose values must be all strings or all numbers (e.g. [100, 101] or ["c", "b"]). The input matches if any of the values in the array matches, similar to the "in" operator. Each label must be unique. If the input type does not match the type of the labels, the result will be the fallback value.
