Field Detail

rnd

private static final java.util.Random rnd

Private source of OK pseudo-random numbers.

Constructor Detail

MemoryToolsTest

public MemoryToolsTest(java.lang.String name)

Method Detail

testBasicGCInteractions

public static void testBasicGCInteractions()

Tests some interactions with the GC system. At least attempts to show that the interactions are not immediately toxic.

testRunMemoryIntensiveOperation

public void testRunMemoryIntensiveOperation()

Simple test of runMemoryIntensiveOperation(). Tests that:

Tasks are always run if we claim to have unlimited memory.
Tasks are always run if we require very limited memory.
Tasks are never run if we demand enormous memory and memory is not unlimited.

TODO: add test that we can run these concurrently without difficulty.

testIntern

public void testIntern()

Test our intern() for various supported data types. This also tests refusal to intern various mutable data types.

testSimpleLRUMapAutoSizeForHitRate

public static void testSimpleLRUMapAutoSizeForHitRate()

Test behaviour of SimpleLRUMapAutoSizeForHitRate.

testSimpleProbabilisticCache

public static void testSimpleProbabilisticCache()

Test behaviour of SimpleProbabilisticCache.
