The Required in Search is giving the following error
[PXSelector(typeof(Search<EPEmployeePosition.employeeID,
Where<EPEmployeePosition.positionID,
Equal<Required<EPEmployeePosition.positionID>>>>.Select(this,'DEV')))]
error CS1012: Too many characters in character literal
error CS1026: ) expected
error CS1003: Syntax error, ']' expected
error CS1519: Invalid token ')' in class, struct, or interface member
declaration
error CS1012: Too many characters in character literal
Can someone let me know how to specify string constant in Search<>
Proper way to achieve this would be with a string constant:
private class Dev : Constant<string>
{
public Dev() : base("DEV")
{
}
}
[PXSelector(typeof(Search<EPEmployeePosition.employeeID,
Where<EPEmployeePosition.positionID,
Equal<Dev>>>))]

Given
open class BaseClass<T: Any>(...) { ... }
class MySubclass<String>(...) : BaseClass<String>(...) { ... }
I get the error
Type argument is not within its bounds
Expected: Any
Found: String
Android Studio offers me Add 'kotlin.Any' as upper bound for String which leads to
// Note the <String: Any> instead of <String>
class MySubclass<String: Any>(...) : BaseClass<String>(...)
But I don't understand why <String> isn't fine but <String: Any> is?
You need to type just
class MySubclass(...) : BaseClass<String>(...) { ... }
Where you put <String> right after MyClass, you've defined a generic type for your subclass named String. And since it has the same name as the actual class String, it's confusing. Usually a single capital letter is used for a generic type. What you wrote would be equivalent to:
class MySubclass<T>: BaseClass<T>()
Which is not allowed because your type is possibly an Any?, which wouldn't satisfy the requirement that the type extend from non-nullable Any.
<String: Any> works because it's like defining a type <T: Any>, which enables it to fit your non-nullable requirement in the base class.
I must be losing it. This class gives an error stating 'Syntax error at '}' on the last line of the file when running puppet agent. Am I missing a brace or other obvious issue?
class roles::webserver::na {
class { 'profiles::webserver::ourwebserver':
market => 'na'
}
Class['profiles::webserver::ourwebserver']
}
..not sure if it helps diagnose, but ourwebserver starts out like so:
class profiles::webserver::ourwebserver($market) {
...
Looks like the problem was with the Class['profiles::webserver::ourwebserver'] bit, apparently with only one class the ordering statement above isn't needed.
``I am learning how to loadImage in cinder.
I used loadImage function defined in ImageIo.h file,
but When I build my code it gives the following error
c:\users\user\particle\src\particleapp.cpp(30): error C2440: 'initializing' : cannot convert from 'ParticleApp *' to 'cinder::app::AppBasic *'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
How to resolve it ?
Trying to guess without seeing your code.
But have you added the parent class type to your ParticleApp class?
Where you declare
class ParticleApp { ... }
you should do:
class ParticleApp : public cinder::app::AppBasic { ... }
How can I get rid of the default ANTLR recognition error?
I want to write another message using my own error class instead of ANTLR's error.
I mean is there any possibility that some ANTLR error classes can be extended in order to display my own message?
More clearly, I do not want to see the following error message in my console :
token recognition error at:
If you simply want to suppress the messages, you can call lexer.removeErrorListeners(). However, a better approach is writing your lexer rules such that all possible input is tokenized, with the following rule at the end of the lexer. This will cause all error reporting to go through the parser instead of both the parser and lexer.
// handle characters which failed to match any other token
ErrorCharacter : . ;
In order to create a custom error handler you can extend the BaseErrorListener class and override the syntaxError method, e.g.:
public class MyErrorListener extends BaseErrorListener {
#Override
public void syntaxError( Recognizer<?, ?> recognizer, Object offendingSymbol, int line, int charPositionInLine,
String msg, RecognitionException e ) {
// method arguments should be used for more detailed report
throw new RuntimeException("syntax error occurred");
}
}
Now when you create a lexer and a parser you should remove the default error listeners and attach your custom one:
MyErrorListener errorListener = new MyErrorListener();
Lexer lexer = new MyLexer( ... );
lexer.removeErrorListeners();
lexer.addErrorListener( errorListener );
CommonTokenStream tokens = new CommonTokenStream( lexer );
Parser parser = new MyParser( tokens );
parser.removeErrorListeners();
parser.addErrorListener( errorListener );
The default message "line x:x token recognition error at: 'xxx'" comes from the default ConsoleErrorListener class. If you don't remove it using lexer/parser.removeErrorListeners() and only add your custom one it will still be triggered.
The error handling strategies are thoroughly described in a dedicated chapter of The Definitive ANTLR4 Reference book (mentioned on the ANTLR4 Documentation page). I currently have no access to the book itself, so would be grateful if someone edits this answer with a concrete page number of the book. Also, I couldn't find a related guide on the ANTLR4 doc page, so if it exists - a link would be helpful, too.
I am using simpldb and am trying to save rahul' mehta in simpledb but it is giving me error below :
Code :
function htmlEscape(text) {
return text.replace(/&/g,'&').
replace(/</g,'<').
replace(/"/g,'"').
replace(/'/g,''');
}
console.log(params.filename);
if (params.filename!=undefined) params.filename=htmlEscape(params.filename);
console.log(sys.inspect(params));
sdb.putItem(domain, params.objectid, params, function( error ) {
});
Output :
rahul' mehta
{
filename: 'rahul' mehta',
}
Error :
{"event":"error","errno":"InvalidQueryExpression","message":"The specified query expression syntax is not valid.","queueno":7}
Why this error is coming , how can i solve it ?
This error is because you are trying to run Amazon SimpleDB SELECT Query and syntax of that query is wrong. This may be because in query -- Attribute Value -- must be unclosed with single quotes i.e. 'Attribute Value', and again if -- Domain Name -- and -- Attribute Name -- contains any special characters then they must be unclosed with acute i.e Domain Name OR Attribute Name. I think you are able to save rahul' mehta but when you are trying to get that saved attribute-value, you are getting this error. http://www.sdbexplorer.com/
