Function Documentation

zfvalueSwitch()

template<typename T_KeyV, typename T_Key, typename T_Hash, typename T_Equal>

zfindex zfvalueSwitch	(	T_KeyV const &	v,
		zfvalueSwitchData< T_Key, T_Hash, T_Equal > const &	data )

util to switch-case on any value type

switch(zfvalueSwitch(v, zfvalueSwitchData<zfstring>()
        .v("111")
        .v("222")
        )) {
    case 0:
        ZFLog("case 111");
        break;
    case 1:
        ZFLog("case 222");
        break;
    default:
        ZFLog("default");
        break;
}

or, store pre initialized switch data for better performance:

// the data can be stored for reuse
zfvalueSwitchData<zfstring> m = zfvalueSwitchData<zfstring>()
    .v("111")
    .v("222")
    ;
 
switch(zfvalueSwitch(v, m)) {
    case 0:
    ...
}
