Method Detail

getSum

@Nullable
BigInteger getSum(@Nullable
                  String sKey)

Parameters:

sKey - The key to be queried.

Returns:

The sum of aggregated values. null if no such key exists.

getMin

@CheckForSigned
long getMin(@Nullable
            String sKey)

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)

Parameters:

sKey - The key to be queried.

Returns:

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