Method Detail

getTimestampFromEpoch

long getTimestampFromEpoch()

Returns the timestamp from the epoch in milliseconds. If the event happened _right now_, this would return the same thing as System.currentTimeMillis();

Returns:

the timestamp from the epoch in milliseconds.

getTimestamp

org.joda.time.DateTime getTimestamp()

Returns the timestamp from the epoch as an org.joda.time.DateTime. If the event happened _right now_, this would return the same thing as new DateTime();

Returns:

the timestamp from the epoch as an org.joda.time.DateTime object.

getDimension

List<String> getDimension(String dimension)

Returns the list of dimension values for the given column name.

Parameters:

dimension - the column name of the dimension requested

Returns:

the list of values for the provided column name

getRaw

Object getRaw(String dimension)

Returns the raw dimension value for the given column name. This is different from #getDimension which all values to strings before returning them.

Parameters:

dimension - the column name of the dimension requested

Returns:

the value of the provided column name

getFloatMetric

float getFloatMetric(String metric)

Returns the float value of the given metric column.

Parameters:

metric - the column name of the metric requested

Returns:

the float value for the provided column name.

getLongMetric

long getLongMetric(String metric)

Returns the long value of the given metric column.

Parameters:

metric - the column name of the metric requested

Returns:

the long value for the provided column name.
