Groovy supports the usual if - else syntax from Java
x = false y = false if ( !x ) { x = true } assert x == true if ( x ) { x = false } else { y = true } assert x == y Groovy also supports the ternary operator
y = 5 x = (y > 1) ? "worked" : "failed" assert x == "worked" switch statementThe switch statement in Groovy is backwards compatible with Java code; so you can fall through cases sharing the same code for multiple matches. One difference though is that the Groovy switch statement can handle any kind of switch value and different kinds of matching can be performed.
x = 1.23 result = "" switch ( x ) { case "foo": result = "found foo" // lets fall through case "bar": result += "bar" case [4, 5, 6, 'inList']: result = "list" break case 12..30: result = "range" break case Integer: result = "integer" break case Number: result = "number" break default: result = "default" } assert result == "number" Switch supports the following kinds of comparisons
How switch worksThe case statement performs a match on the case value using the isCase(switchValue) method, which defaults to call equals(switchValue) but has been overloaded for various types like Class or regex etc. So you could create your own kind of matcher class and add an isCase(switchValue) method to provide your own kind of matching. |
