Parameters:

sKey - The key to be queried.

Returns:

The smallest value. Returns CGlobal.ILLEGAL_ULONG if no such key exists.

getAverage

@CheckForSigned
long getAverage(@Nullable
                             String sKey)

Parameters:

sKey - The key to be queried.

Returns:

The average value (=sum/invocationCount). Returns CGlobal.ILLEGAL_ULONG if no such key exists.

getMax

@CheckForSigned
long getMax(@Nullable
                         String sKey)
