Field Summary

Fields

Modifier and Type	Field and Description
static Long	boundsMultiplier (int) The multiplier for the bound point when determining the dynamic capacity of a region.
static Long	byteArraySize (int) The size for byte[] objects, used as values in regions that have MemLRUCapacityControllers installed.
static Long	endTaskSecToRun (int) The number of seconds to run the end task.
static Long	fillByteArray (boolean) Indicates if byte[] should be filled with bytes.
static Long	fixUseCacheLoader (boolean) If true, the test will read the value of useCacheLoader once and use that value throughout the test.
static Long	lowerLimitDelta (int) Specifies a lower limit on the number of bytes that must be present in a region (for memLRU) for eviction to occur.
static Long	LRUAllowance (int) Since eviction of objects by capacity controllers is "roughly" the least recently used object, this specifies how far an evicted object can be from the actual least recently used object.
static Long	maximumEntries (int) The size for byte[] objects, used as values in regions that have memory evictors installed.
static Long	maximumMegabytes Parameters for constructing a MemLRUCapacityController.
static Long	numToAddInTx (int) The number of objects to add to a region during a transactions.
static Long	randomCapacityChanges (boolean) True if dynamic capacity changes during the test should be random, false if they should gradually climb and fall.
static Long	upperLimitDelta (int) Specifies an upper limit on the number of bytes allowable as overage for memlru.
static Long	useCacheLoader (boolean) If true, the test will install a CacheLoader and do gets to fill the region, false if the test should do puts to fill the region.
static Long	useTransactions (boolean) True if the test should use transactions, false otherwise.

Field Detail

maximumEntries

public static Long maximumEntries

(int) The size for byte[] objects, used as values in regions that have memory evictors installed.

maximumMegabytes

public static Long maximumMegabytes

Parameters for constructing a MemLRUCapacityController. (int) The maximumMegabytes parameter for creating a new MemLRUCapacityController.

byteArraySize

public static Long byteArraySize

(int) The size for byte[] objects, used as values in regions that have MemLRUCapacityControllers installed.

fillByteArray

public static Long fillByteArray

(boolean) Indicates if byte[] should be filled with bytes.

upperLimitDelta

public static Long upperLimitDelta

(int) Specifies an upper limit on the number of bytes allowable as overage for memlru. This number is the number of bytes higher than the maximumMegabytes setting on the controller (ie. upperThreshold = maximumMegabytes + upperLimitDelta). The size of the region must not go over this threshold.

lowerLimitDelta

public static Long lowerLimitDelta

(int) Specifies a lower limit on the number of bytes that must be present in a region (for memLRU) for eviction to occur. This number is the number of bytes lower than the maximumMegabytes setting on the controller (ie. lowerThreshold = maximumMegabytes - lowerLimitDelta). Evictions must occur at this threshold or higher.

endTaskSecToRun

public static Long endTaskSecToRun

(int) The number of seconds to run the end task.

LRUAllowance

public static Long LRUAllowance

(int) Since eviction of objects by capacity controllers is "roughly" the least recently used object, this specifies how far an evicted object can be from the actual least recently used object. For example, a 3 means that an evicted object can be the 1st, 2nd or 3rd least recently used objects and the test will allow it.

useCacheLoader

public static Long useCacheLoader

(boolean) If true, the test will install a CacheLoader and do gets to fill the region, false if the test should do puts to fill the region.

fixUseCacheLoader

public static Long fixUseCacheLoader

(boolean) If true, the test will read the value of useCacheLoader once and use that value throughout the test. This is useful for specifying useCacheLoader with a ONEOF; setting this to true will read the ONEOF value once and use it throughout the entire test. A setting of false would get a potentially different value of useCacheLoader each time it is read in the test (if ONEOF is used), thus making the test randomly alternate between using a cache loader or not within one run.

boundsMultiplier

public static Long boundsMultiplier

(int) The multiplier for the bound point when determining the dynamic capacity of a region.

randomCapacityChanges

public static Long randomCapacityChanges

(boolean) True if dynamic capacity changes during the test should be random, false if they should gradually climb and fall.

useTransactions

public static Long useTransactions

(boolean) True if the test should use transactions, false otherwise.

numToAddInTx

public static Long numToAddInTx

(int) The number of objects to add to a region during a transactions. Currently used only in evict tests.
