Progress Unknown Values
The Progress unknown value (?) is mapped to a Java object with a null value. However, the
int
,boolean
, andlong
data types are intrinsic types, not Java classes. So, the null value does not belong to the set of values they support. If a proxy is generated to support Progress unknown values, parameters that would otherwise be intrinsic data types are instead generated as Java classes. For example, ProxyGen generates anInteger
parameter instead of anint
, aBoolean
parameter instead of aboolean
, and aLong
parameter instead oflong
.The following is an example of a proxy method signature that does not support Progress unknown values for the lst and 3rd parameter:
This is an example of a proxy method that allows all the parameter values to have unknown values:
