| Create PsiJavaFile from PsiFile(plain text) | |
| Hi, | |
| I apologize if this is really basic but, after much searching in the forums, I still haven't found the answer. I have some java source files that exist within my project's content root but outside of any source paths. When examining the virtual files associated to each of the java files, they are all identifed as PsiFile(plain text), and their language is TEXT. | |
| How can I turn such a reference into a PsiJavaFile reference so that I can manipulate/query its structure? The ultimate goal is to obtain the package of the file so that I can resolve the proper parent folder and add it to the source path. | |
| Thank you very much, | |

| Re: Create PsiJavaFile from PsiFile(plain text) | |
| Thanks Maxim, it worked great. | |
| For the sake of completeness on this post, I offer this example code block which, given a "whatever.java" virtual file, will parse it into a PsiJavaFile if it's not already one. | |
| if ( !virtualFile.isDirectory() && "java".equalsIgnoreCase(virtualFile.getExtension()) ) | |
| { | |
| PsiManager psiMgr = PsiManager.getInstance(mProject); | |
| PsiFile file = psiMgr.findFile(virtualFile); | |
| if ( !(file instanceof PsiJavaFile) ) | |
| { | |
| PsiJavaFile jFile = PsiJavaFile)psiMgr.getElementFactory().createFileFromText("temp.java", file.getText()); | |
| // do whatever you want with your PsiJavaFile | |
| } | |
| } | |
| The file "temp.java" is not created anywhere, it's simply a token name. The extension of the name, however, is important since it will indicate to the factory which parser to use. | |
| Regards, | |

How do I create one?
The PsiFileFactory .getInstance(project).createFileFromText() method creates an in-memory PSI file with the specified contents. To save the PSI file to disk, use the PsiDirectory .add() method.
