- All Implemented Interfaces:
GssFunction
- Enclosing class:
- GssFunctions
public static class GssFunctions.SelectFrom extends java.lang.Object implements GssFunction
Allows the equivalent of the ternary operator in GSS, using three@defstatements as inputs. This GSS:@def MYDEF selectFrom(FOO, BAR, BAZ);implies:
MYDEF = FOO ? BAR : BAZ;So this gss:
@def FOO true;then implies:
MYDEF = BAR;
