Handling
enumerated types
The GetEnumItemValue and GetEnumItemName functions allow you to
convert the name of an enumerated value to an integer value, and to
convert an integer value to the name of an enumerated value.
This example gets the numeric value for the boolean! enumerated
value, then uses it to return the string value:
|
1 2 3 4 |
pblong lType = session->GetEnumItemValue("object", boolean" ); // returns 138 LPCTSTR szEnum = session->GetEnumItemName( "object", lType ); // returns "boolean" |
Notice that the second argument in the GetEnumItemValue call, the
enumerated value, must not have an appended exclamation mark (!).
To return an enumerated value from an extension to PowerScript, use
the SetLong function to set the value of the enumerated variable into
IPB_Value (you cannot use SetInt or SetShort).
To obtain an enumerated variable’s value, you can use GetInt or
GetShort as well as GetLong, as long as the value is in the appropriate
range. For example, if you attempt to use GetInt to obtain a value that is
more than 32767, the returned value is truncated.
