TransformedInputRow

public TransformedInputRow(InputRow row,
 Map<String,RowFunction> transforms)

Method Details

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 column)

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 converts all values to strings before returning them.

Specified by:

getRaw in interface Row

Parameters:

column - 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, null will be returned. 2. If the column has string value, an attempt is made to parse this value as a number.

Specified by:

getMetric in interface Row

getBaseRow

public InputRow getBaseRow()

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

compareTo

public int compareTo(Row o)

Specified by:

compareTo in interface Comparable<Row>

toString

public String toString()

Overrides:

toString in class Object
