DocumentCacheTest
public class DocumentCacheTest extends DrJavaTestCase (Code)
This used to extend GlobalModelTestCase, but now it extends just TestCase. Perhaps it should be changed back.


Field Summary
protected  File_tempDir
    


Method Summary
protected  voidcreateModel()
     Instantiates the GlobalModel to be used in the test cases.
protected  OpenDefinitionsDocumentopenFile(File f)
    
public  voidsetUp()
    
public  voidtearDown()
    
protected  FiletempFile()
     Create a new temporary file in _tempDir.
protected  FiletempFile(int i)
     Create a new temporary file in _tempDir.
public  voidtestCacheSize()
     A good warmup test case.
public  voidtestGetDDocFromCache()
    
public  voidtestMemoryLeak()
     There used to be a memory leak where various listeners, LeafElements, and other extraneous references from the model, definitions pane, and main frame would be preventing the definitions panes/documents from being GC'd at the correct times causing the entire program to run out of heap space when working with large numbers of files.
public  voidtestNewDocumentsInAndOutOfTheCache()
    
public  voidtestNoDDocInCache()
    
public  voidtestNumListeners()
    
public  voidtestOldDocumentsInAndOutOfTheCache()

Field Detail
_tempDir
protected File _tempDir(Code)





Method Detail
createModel
protected void createModel()(Code)
Instantiates the GlobalModel to be used in the test cases.



openFile
protected OpenDefinitionsDocument openFile(File f) throws IOException(Code)



setUp
public void setUp() throws Exception(Code)



tearDown
public void tearDown() throws Exception(Code)



tempFile
protected File tempFile() throws IOException(Code)
Create a new temporary file in _tempDir.



tempFile
protected File tempFile(int i) throws IOException(Code)
Create a new temporary file in _tempDir. Calls with the same int will return the same filename, while calls with different ints will return different filenames.



testCacheSize
public void testCacheSize()(Code)
A good warmup test case.



testGetDDocFromCache
public void testGetDDocFromCache() throws BadLocationException, IOException, OperationCanceledException(Code)



testMemoryLeak
public void testMemoryLeak() throws InterruptedException, IOException(Code)
There used to be a memory leak where various listeners, LeafElements, and other extraneous references from the model, definitions pane, and main frame would be preventing the definitions panes/documents from being GC'd at the correct times causing the entire program to run out of heap space when working with large numbers of files. This problem was agrivated when we added project facility and implemented the document cache (which was supposed to solve our memory problem but actually worsened it).

Adam and Jonathan went through great pains to remove these references, so don't break our work!!!




testNewDocumentsInAndOutOfTheCache
public void testNewDocumentsInAndOutOfTheCache() throws BadLocationException, IOException(Code)



testNoDDocInCache
public void testNoDDocInCache()(Code)



testNumListeners
public void testNumListeners()(Code)



testOldDocumentsInAndOutOfTheCache
public void testOldDocumentsInAndOutOfTheCache() throws BadLocationException, IOException(Code)



testReconstructor
public void testReconstructor() throws IOException(Code)
