Method Details

getItemCount

public int getItemCount(int series,
 Map<Integer,List<ValidObservation>> seriesNumToObSrcListMap)

The number of JD items is the size of the mapped series list.

Specified by:

getItemCount in interface ICoordSource

Parameters:

series - The series of interest.

Returns:

The number of items in this series.

getXCoord

public double getXCoord(int series,
 int item,
 Map<Integer,List<ValidObservation>> seriesNumToObSrcListMap)

Get the Julian Day associated with the specified series and item.

Specified by:

getXCoord in interface ICoordSource

Parameters:

series - The series of interest.

item - The target item.

seriesNumToObSrcListMap - A mapping from series number to a list of observations.

Returns:

The X coordinate (Julian Day).

getXCoord

public double getXCoord(int item,
 List<ValidObservation> obs)

Get the JD coordinate value associated with the specified item.

Specified by:

getXCoord in interface ICoordSource

Parameters:

item - The target item.

obs - A list of observations.

Returns:

The JD.

getActualYItemNum

public int getActualYItemNum(int series,
 int item,
 Map<Integer,List<ValidObservation>> seriesNumToObSrcListMap)

The actual item number for the Y coordinate is in fact, just item in this case.

Specified by:

getActualYItemNum in interface ICoordSource

Parameters:

series - The series of interest.

item - The target item.

seriesNumToObSrcListMap - A mapping from series number to a list of observations.

Returns:

The actual Y item number.

getValidObservation

public ValidObservation getValidObservation(int series,
 int item,
 Map<Integer,List<ValidObservation>> seriesNumToObSrcListMap)

Given a series and item number, return the corresponding observation.

Specified by:

getValidObservation in interface ICoordSource

Parameters:

series - The series number.

item - The item within the series.

seriesNumToObSrcListMap - A mapping from series number to a list of observations.

Returns:

The valid observation.

Throws:

IllegalArgumentException - if series or item are out of range.

getUnit

public String getUnit()

Description copied from interface: ICoordSource

Return the time unit.

Specified by:

getUnit in interface ICoordSource

Returns:

the time unit string.
