I defined a property in the constructor of my class the following way:
class Step(val message:String = "")
When I try access to message value from Java code y get a visbility error. Why?
I have these classes.
class Author{
Person person
}
class Person{
String lastName
String firstName
String middleName
}
I'd like to query Person and Author.
def persons = Person.findAllByLastNameiLike("${a}")
but it seems I can't do
def authors = Author.findAllByPerson(persons)
Any ideas how I'd do this?
I would like to create a base class that is somewhat generic for all of my entities. The class would have methods like Save(), Delete(), GetByID() and some other basic functionality and properties. I have more experience with Linq to SQL and was hoping to get some good examples for something similar in the EF. Thank you.
Hi
We can resrict the creation of object of a class by making it's constructor private.
But this constructor could still be called from within the class.
is there anyway to prevent this in Java?
Thnx.
Given the Thread class with it current method.
Now inside a test, I want to do this:
def test_alter_current_thread
Thread.current = a_stubbed_method
# do something that involve the work of Thread.current
Thread.current = default_thread_current
end
Basically, I want to alter the method of a class inside a test method and recover it after that.
I know it sound complex for another language, like Java & C# (in Java, only powerful mock framework can do it). But it's ruby and I hope such nasty stuff would be available
Flash has a scrollbar class, documented here:
http://help.adobe.com/en_US/AS3LCR/Flash_10.0/fl/controls/ScrollBar.html
However, besides listing functions and variables, there's no real explanation of how to hook an instance of this class to a textfield.
Everything I've tried either ends up in errors or the scrollbar not showing. The documentation lacks a clear way of how you should bind the textfield and the scrollbar toghether, and CS4 isn't providing any help either.
Can someone explain, or link to an example of how scrollbars work with textfield?

When creating a mixed mode class, on compilation the header file complains that it needs to be complied with the /clr switch as it is a mixed mode class, however, I can't see any option to specifically compile that header with /clr from visual studio, and I don't want to set the entire project with a /clr flag,
Does anyone know how I can specify that this header file is compiled correctly with /clr?
Thanks in advance!
Suppose you want to throw Exception like this:
'Project with the provided ID cannot be assigned.'
and you don't want to write your custom Exception class. What predefined Exception class would you use for this?
(I'm talking about all classes inheriting from Exception)
Hi
I new to python and I read from someone else of the example code below:
class A:
def current(self):
data = Data(a=a,b=b,c=c)
return data
class B(A):
#something here
#print data a b c
How do I print out the data a, b, and c?
I have a jython servlet as part of a large application running in tomcat5. I tested a few Spring Framework classes and create the objects in the Jython servlet. When I try to create objects of classes in the application I catch an Exception message "No visible constructors for class". These java classes do have a public constructor class, such as:
public SchoolImpl() {
}
I create the object in python:
from com.dc.sports.entity import SchoolImpl
...
school = SchoolImpl()
What am I doing wrong?
How do I go from a Class object to a list of enums generically?
i.e.
public static <T extends Enum> List<T> getList(Class<T> clazz)
I cant find a way to get to the values() method
Hey all, I'm working on building my own string class with very basic functionality. I am having difficulty understand what is going on with the basic class that I have define, and believe there is some sort of error dealing with the scope occurring. When I try to view the objects I created, all the fields are described as (obviously bad pointer). Also, if I make the data fields public or build an accessor method, the program crashes. For some reason the pointer for the object is 0xccccccccc which points to no where.
How can a I fix this? Any help/comments are much appreciated.

Let's assume I have a class ClassWithMember
class ClassWithMember
{
int myIntMember = 10;
}
How do I get the default value 10 of the myIntMember member by System.Type?
I'm currently struggling around with reflections by all I retreive is the default value of int (0) not the classes default member (10)..
How do I create a Zend_Db_Table which returns a different class for each row.?
Example
UserTable has id,name and type
Type contains class names (admin,client,etc...)
The classes admin, client are all subclasses of user
If I call fetch I need to get a admin or client object depending on the corresponding value in the db.
I have a page that has the following div structure:
<div id="name" class="class_name">
How would I style the class?
Like this?
#name .class_name
name .class_name
#name class_name
?
Hello, I want to do a class thats accepts anything ordered and prints greater. (I'm just learning so I know it's a bit useless)
class PrinterOfGreater[T extends Ordered](val a:T, val b:T){println(a > b)}
I know that it can't be written by this style in scala, but I don't know how to write it properly... Do anybody know?
I have a variable called $theclass and it's a string "Home_class". How can I define a class out of that string? The reason I need to do this is that the variable will change and I want to be able to declare the class that the variable is equal to. Is this possible?
Thanks for any help.
What is the difference between the following class methods?
Is it that one is static and the other is not?
Class Test(Object):
def method_one(self):
print "Called method_one"
def method_two():
print "Called method_two"
a_test = Test()
a_test.method_one()
a_test.method_two()
Hi,
Is some one able to explain why header files have something like this?
class foo; // This here?
class bar
{
bar();
};
Do you need an include statement when using this?
Thanks.
I want to know how can we open a file dialog from withing a class module in vb6. I know how to do in forms, but I have to open it from within a class module.
Why on earth won't this compile? Scala 2.8.0RC3:
Java
public interface X {
void logClick(long ts, int cId, String s, double c);
}
Scala
class Y extends X {
def logClick(ts: Long, cId: Int,sid: java.lang.String,c: Double) : Unit = {
...
}
}
Error
class Y needs to be abstract, since method logClick in trait X of type
(ts: Long,cId: Int,s: java.lang.String,c: Double)Unit is not defined
It is possible to call methods on a class whose interface is not exposed through an .idl file?
Im my particular case I'd like to use the @mozilla.org/gfx/fontmetrics;1 class, whose interface nsIFontMetrics doesn't have a correspondent .idl file.
