Method Detail

createCache

protected abstract BaseCache<java.lang.Integer,java.lang.Object> createCache()

Creates a cache instance.

Returns:

A Cache instance

createCache

protected abstract BaseCache<java.lang.Integer,java.lang.Object> createCache(int capacity)

Creates a cache instance.

Parameters:

capacity - Initial capacity

Returns:

A Cache instance

createCache

protected abstract BaseCache<java.lang.Integer,java.lang.Object> createCache(int capacity,
                                                                             float factor)

Creates a cache instance.

Parameters:

capacity - Initial capacity

factor - Load factor

Returns:

A Cache instance

createCache

protected abstract BaseCache<java.lang.Integer,java.lang.Object> createCache(int capacity,
                                                                             float factor,
                                                                             int level)

Creates a cache instance.

Parameters:

capacity - Initial capacity

factor - Load factor

level - Concurrency level

Returns:

A Cache instance

testGet

public final void testGet()

Test for Cache.get(Object).

testRemove

public final void testRemove()

Test for Cache.remove(Object).

testPurge

public final void testPurge()

Tests that the cache has the correct number of items after a purge().

testUnsupported

public final void testUnsupported()

Test for unsupported methods in BaseCache.

testRemoveAndPut

public final void testRemoveAndPut()

Tests that the following sequence:

• cache.put(key, x)
• cache.remove(key)
• cache.put(key, y)

Is safe. This is, after a purge(), the cache MUST still maintain the association [key, y].

testObjectMethods

public final void testObjectMethods()

Test for some methods inherited from Object.

testProfiler

public final void testProfiler()

Test for CacheProfiler.

forcePurge

protected final void forcePurge()

Utility method that forces caches to be purged by demanding a huge amount of memory.

check

protected final void check(long[] a1,
                           long[] a2)

Tests two arrays for equality.

Parameters:

a1 - Left array

a2 - Right array

check

protected final void check(double[] a1,
                           double[] a2)

Tests two arrays for equality.

Parameters:

a1 - Left array

a2 - Right array
