Field Summary

Fields

Modifier and Type	Field and Description
static java.lang.Long	boundsMultiplier (int) The multiplier for the bound point when determining the dynamic capacity of a region.
static java.lang.Long	byteArraySize (int) The size for byte[] objects, used as values in regions that have MemLRUCapacityControllers installed.
static java.lang.Long	endTaskSecToRun (int) The number of seconds to run the end task.
static java.lang.Long	fillByteArray (boolean) Indicates if byte[] should be filled with bytes.
static java.lang.Long	fixUseCacheLoader (boolean) If true, the test will read the value of useCacheLoader once and use that value throughout the test.
static java.lang.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 java.lang.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 java.lang.Long	maximumEntries (int) The size for byte[] objects, used as values in regions that have memory evictors installed.
static java.lang.Long	maximumMegabytes Parameters for constructing a MemLRUCapacityController.
static java.lang.Long	numToAddInTx (int) The number of objects to add to a region during a transactions.
static java.lang.Long	randomCapacityChanges (boolean) True if dynamic capacity changes during the test should be random, false if they should gradually climb and fall.
static java.lang.Long	upperLimitDelta (int) Specifies an upper limit on the number of bytes allowable as overage for memlru.
static java.lang.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 java.lang.Long	useTransactions (boolean) True if the test should use transactions, false otherwise.

Field Detail

maximumEntries

public static java.lang.Long maximumEntries

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

maximumMegabytes

public static java.lang.Long maximumMegabytes

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

byteArraySize

public static java.lang.Long byteArraySize

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

fillByteArray

public static java.lang.Long fillByteArray

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

upperLimitDelta

public static java.lang.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 java.lang.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 java.lang.Long endTaskSecToRun

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

LRUAllowance

public static java.lang.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 java.lang.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 java.lang.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 java.lang.Long boundsMultiplier

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

randomCapacityChanges

public static java.lang.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 java.lang.Long useTransactions

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

numToAddInTx

public static java.lang.Long numToAddInTx

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