Read the clipboard data in chunks and save it to a tmp log file.If we do decide to change the implementation so that we can handle the message in a more performant way, the fix above would not apply anymore since we would not be running out of memory, but there would be other changes in the application that we would need to make: This way the the application fails gracefully, not showing the exception stack trace.
Java parse text clipboard how to#
Display a message to inform the end user that the data in the clipboard exceeds the memory limit configured for the application, and explain the steps on how to configure the limit. The following examples show how to use can vote up the ones you like or vote down the ones you dont like, and go to the original project or source file by following the links above each example.In general, each read request made of a Reader causes a corresponding. The default is large enough for most purposes. The buffer size may be specified, or the default size may be used. It does buffer for efficient reading of characters, arrays, and lines. The pro is that we can handle it the same way than any other log file, though I tried loading the 80Mb file that I created into OLV and it also slapped me with an OutOfMemoryError, which means that we are loading the whole file into memory when we are parsing it, and that also need to be improved. This method reads text from a character-input stream. See solution number 1 (I thought I had another one, really) Best Java code snippets using .getString (Showing top 8 results out of 315) getString if (text.length() > 2 & text.charAt(0).That way can support larger amounts of data pasted from the clipboard without having to modify the memory allocated for the java process. The tmp file would need to be deleted on exit. We could change the implementation to read the clipboard data in chunks and save it into a temporary file in disk, then we treat it as any other file.I don't think there is anything documented regarding on how much data we should be able to handle in the "Paste clipboard" functionality, but I have 2 possible solutions: Local Clipboard s are visible only within a single Java application. It corresponds to the usual idea of sharing data between otherwise independent applications running on the same computer. The following example uses the system Clipboard.
Java parse text clipboard full#
Once I changed that to the value in the example above, I was able to paste the full log. In Java, there are actually two kinds of Clipboard - system and local. The default value is -Xmx1024m and with that value I was able to reproduce your problem.
