Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Is it impossible to have two files whose name is same prefix?

I want to separate interface and class file like Pimpl pattern. In "TestObject.h", class code is like this,

 class ITestObject
 {
 public:
     virtual void DoSomething() = 0;
 };

and In "TestObjectImpl.h", class code is like this,

 #include "TestObject.h"
 #include "TestObjectImpl.generated.h"
 
 UCLASS()
 class UTestObject : public UObject, public ITestObject
 {
     GENERATED_BODY()
 public:
     void DoSomething() override {}
 };

Then, this kinds of error occur.

Class 'UTestObject' contains a dependency (#include or base class) to itself. I found a similar question at here. https://answers.unrealengine.com/questions/305304/cannot-include-file-with-the-same-name-but-other-d.html I guess it's some magic of UHT, but I don't know how to workaround.

The class name should be changed. After chaning UTestObject to UTestObjectImpl, compiling is success. I guess UE4 treat UTestObject and ITestObject as same class name. :(
