int getMaxValuesCount()

Returns maximum allowed count of values.

Returns:

Maximum allowed count of values.

getCalculatedTargetName

java.lang.String getCalculatedTargetName()

Returns a name of a target attribute for which statistics was calculated.

Returns:

Name of a target attribute. null if statistics for target attribute weren't calculated.
