Dear list,
I am trying to return a distinct list of objects via the
EOFetchSpecification. I¹ve always had good luck with the simple
³EOFetchSpecification spec = new EOFetchSpecification("myentity", qualifier,
null);² statement. But when I try adding a boolean to the ŒusesDistinct¹
parameter of the constructor I get an error. ie. neither of these work:
EOFetchSpecification spec = new EOFetchSpecification("SyncShared",
qualifier, myOrderings, boolTrue);
-or-
EOFetchSpecification spec = new EOFetchSpecification("SyncShared",
qualifier, null, boolTrue);
The API does list this forth parameter as a boolean (true means distinct,
false otherwise).
public EOFetchSpecification(String entityName,
EOQualifier qualifier,
NSArray sortOrderings,
boolean usesDistinct,
boolean isDeep,
NSDictionary hints)
Here is the error I get when I try to build:
syncaccountcreate.java:42: cannot resolve symbol
symbol : constructor EOFetchSpecification
(java.lang.String,com.webobjects.eocontrol.EOQualifier,com.webobjects.founda
tion.NSArray,boolean)
Thanks for any guidance, and for pointing out what my be painfully simple.
:)

Your trying to call a method that does not exist. The error above is
telling you that you have the wrong arguments in your method call. Your
method call arguments are:
String,
EOQualifier,
NSArray,
boolean
But the signature you have listed from the api has five arguments.
String,
EOQualifier,
NSArray,
boolean,
NSDictionary
