Class SegmentInputRow

java.lang.Object

io.druid.indexer.hadoop.SegmentInputRow

All Implemented Interfaces:

InputRow, Row, Comparable<Row>

public class SegmentInputRow
extends Object
implements InputRow

SegmentInputRow serves as a marker that these InputRow instances have already been combined and they contain the columns as they show up in the segment after ingestion, not what you would see in raw data. It must only be used to represent such InputRows.

                       List<String> dimensions)

Method Detail

getDimensions

public List<String> getDimensions()

Description copied from interface: InputRow

Returns the dimensions that exist in this row.

Specified by:

getDimensions in interface InputRow

Returns:

the dimensions that exist in this row.

getTimestampFromEpoch

public long getTimestampFromEpoch()

Description copied from interface: Row

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

Specified by:

getTimestampFromEpoch in interface Row

Returns:

the timestamp from the epoch in milliseconds.

getTimestamp

public org.joda.time.DateTime getTimestamp()

Description copied from interface: Row

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();

Specified by:

getTimestamp in interface Row

Returns:

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

getDimension

public List<String> getDimension(String dimension)

Description copied from interface: Row

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

Specified by:

getDimension in interface Row

Parameters:

dimension - the column name of the dimension requested

Returns:

the list of values for the provided column name

getRaw

public Object getRaw(String dimension)

Description copied from interface: Row

Returns the raw dimension value for the given column name. This is different from Row.getDimension(java.lang.String) which all values to strings before returning them.

Specified by:

getRaw in interface Row

Parameters:

dimension - the column name of the dimension requested

Returns:

the value of the provided column name

getMetric

public Number getMetric(String metric)

Description copied from interface: Row

Returns the metric column value for the given column name. This method is different from Row.getRaw(java.lang.String) in two aspects: 1. If the column is absent in the row, numeric zero is returned, rather than null. 2. If the column has string value, an attempt is made to parse this value as a number.

Specified by:

getMetric in interface Row

compareTo

public int compareTo(Row row)

Specified by:

compareTo in interface Comparable<Row>

toString

public String toString()

Overrides:

toString in class Object
