Method Detail

addLongStat

void addLongStat(MetricDef metric,
                 long value)

Add a long value to the existing value. Creates the stat (with an initial value of zero) if the stat does not yet exist.

Parameters:

metric - the metric to update

value - the value to add to the existing value

addDoubleStat

void addDoubleStat(MetricDef metric,
                   double value)

Add a double value to the existing value. Creates the stat (with an initial value of zero) if the stat does not yet exist.

Parameters:

metric - the metric to update

value - the value to add to the existing value

setLongStat

void setLongStat(MetricDef metric,
                 long value)

Set a stat to the specified long value. Creates the stat if the stat does not yet exist.

Parameters:

metric - the metric to update

value - the value to set

setDoubleStat

void setDoubleStat(MetricDef metric,
                   double value)

Set a stat to the specified double value. Creates the stat if the stat does not yet exist.

Parameters:

metric - the metric to update

value - the value to set
