  • Constructor Details

    • CodeReaderCache

      public CodeReaderCache(int size)
      Deprecated.
      Creates a CodeReaderCache and sets the size of the CodeReaderCache in MB. Creating a new CodeReaderCache also adds an UpdateCodeReaderCacheListener to the workspace so that when a resource is changed then the CodeReader for that resource is removed from this cache.
      Parameters:
      size - initial size of the CodeReaderCache in terms of MB

  • Method Details

    • finalize

      protected void finalize() throws Throwable
      Deprecated.
      Overrides:
      finalize in class Object
      Throws:
      Throwable

    • get

      public CodeReader get(String key)
      Deprecated.
      Get a CodeReader from the cache. The key is the char[] filename of the CodeReader to retrieve.
      Specified by:
      get in interface ICodeReaderCache
      Parameters:
      key - the path of the CodeReader to retrieve
      Returns:
      the CodeReader corresponding to the path specified by the key

    • get

      public CodeReader get(String key, IIndexFileLocation ifl) throws org.eclipse.core.runtime.CoreException, IOException
      Deprecated.
      Description copied from interface: ICodeReaderCache
      Retrieves the CodeReader corresponding to the key specified that represents the path for that CodeReader. If no CodeReader is found in the cache then a new CodeReader is created for the ifl and then returned.
      Specified by:
      get in interface ICodeReaderCache
      Parameters:
      key - the path corresponding to the CodeReader, generally: fileToParse.getLocation().toOSString()
      Returns:
      the CodeReader corresponding to the path specified by the key
      Throws:
      IOException
      org.eclipse.core.runtime.CoreException

    • remove

      public CodeReader remove(String key)
      Deprecated.
      Removes the CodeReader from the cache corresponding to the path specified by the key and returns the CodeReader that was removed. If no CodeReader is removed then null is returned.
