org.javarosa.core.util.MemoryUtils

public class MemoryUtils
extends Object

J2ME suffers from major disparities in the effective use of memory. This class encompasses some hacks that sadly have to happen pertaining to high memory throughput actions. This was implemented in a hurry, and urgently needs a major refactor to be less... hacky, static, and stupid.

printMemoryTest

public static void printMemoryTest()

Prints a memory test debug statement to stdout. Requires memory printing to be enabled, otherwise is a no-op

printMemoryTest

public static void printMemoryTest(String tag)

Prints a memory test debug statement to stdout with a tag to reference Requires memory printing to be enabled, otherwise is a no-op

Parameters:

tag -

printMemoryTest

public static void printMemoryTest(String tag,
                                   int pause)

Prints a memory test debug statement to stdout with a tag to reference. After printing the message the app waits for Pause milliseconds to allow profiling Requires memory printing to be enabled, otherwise is a no-op

Parameters:

tag -

pause -

profileMemory

public static void profileMemory()

Experimental. This method builds a profile of what the current memory allocation looks like in the current heap. You must initialize the profiler once in your app (preferably immediately upon entering) to pre-allocate the space for the profile.
