getCacheLevelInfo	back to summary
public static CacheLevelInfo getCacheLevelInfo(int index) Get the CPU cache level information for a cache level. The `index` argument must be greater than zero and less than the number of levels returned by `getLevelEntryCount()`. Parameters index:int the cache level index Returns:CacheLevelInfo the CPU cache level information

public static CacheLevelInfo getCacheLevelInfo(int index)

Get the CPU cache level information for a cache level. The index argument must be greater than zero and less than the number of levels returned by getLevelEntryCount().

Parameters

index:int: the cache level index

Returns:CacheLevelInfo

the CPU cache level information

getLevelEntryCount	back to summary
public static int getLevelEntryCount() Get the number of CPU cache level entries. If no cache information could be gathered, 0 is returned. Returns:int the number of CPU cache levels, or 0 if unknown

getLevelEntryCount

back to summary

public static int getLevelEntryCount()

Get the number of CPU cache level entries. If no cache information could be gathered, 0 is returned.

Returns:int: the number of CPU cache levels, or 0 if unknown

getSmallestDataCacheLineSize	back to summary
public static int getSmallestDataCacheLineSize() Get the smallest known data cache line size. If no cache line sizes are known, 0 is returned. Note that smaller cache lines may exist if one or more cache line sizes are unknown. Returns:int the smallest cache line size, or 0 if unknown

getSmallestDataCacheLineSize

back to summary

public static int getSmallestDataCacheLineSize()
