Package com.google.common.css.compiler.gssfunctions

Class GssFunctions.SelectFrom

java.lang.Object

com.google.common.css.compiler.gssfunctions.GssFunctions.SelectFrom

All Implemented Interfaces:

GssFunction

Enclosing class:

GssFunctions

public static class GssFunctions.SelectFrom
extends Object
implements GssFunction

Allows the equivalent of the ternary operator in GSS, using three @def statements 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;
