Method Details

getColumnIndex

public int getColumnIndex(String colName)

Returns the index of the given column, case-insensitive

Specified by:

getColumnIndex in interface Dataset

Parameters:

colName - the name of the column to look upw

Returns:

the index of the column

Throws:

ArrayIndexOutOfBoundsException - if the column doesn't exist

getColumnCount

public int getColumnCount()

Description copied from interface: Dataset

Returns the number of columns.

Specified by:

getColumnCount in interface Dataset

getColumnNames

public List<String> getColumnNames()

Description copied from interface: Dataset

Returns an unmodifiable list of this dataset's column names, in order.

Specified by:

getColumnNames in interface Dataset

getColumnName

public String getColumnName(int col)

Description copied from interface: Dataset

Returns the name of the given column.

Specified by:

getColumnName in interface Dataset

getColumnTypes

public List<Class<?>> getColumnTypes()

Description copied from interface: Dataset

Returns an unmodifiable list of this dataset's column types, in order.

Specified by:

getColumnTypes in interface Dataset

getColumnType

public Class<?> getColumnType(int col)

Description copied from interface: Dataset

Returns the type of the given column.

Specified by:

getColumnType in interface Dataset

setColumnNames

protected void setColumnNames(List<String> list)

setColumnTypes

protected void setColumnTypes(List<Class<?>> list)

setDirty

protected void setDirty()

getPrimitiveValueAt

public double getPrimitiveValueAt(int row,
 int col)

If the given column is a numeric type or a Date, then the value will be returned as a double. The Chart uses this functionality to provide a seamless interface with the optimized dataset.

Specified by:

getPrimitiveValueAt in interface Dataset

getValueAt

public Object getValueAt(int row,
 String colName)

Returns the value at the given row and at a column named colName. Column name matching is case insensitive.

Specified by:

getValueAt in interface Dataset

getQualityAt

public QualityCode getQualityAt(int row,
 int col)

Description copied from interface: Dataset

Returns the quality of the value at the given location.

Specified by:

getQualityAt in interface Dataset

hasQualityData

public boolean hasQualityData()

Description copied from interface: Dataset

Whether this dataset has any quality data to report. If false, getQualityAt is expected to return QualityCode.Good.

Specified by:

hasQualityData in interface Dataset

See Also:

• Dataset.getQualityAt(int, int)

getBulkQualityCodes

public QualityCode[][] getBulkQualityCodes()

getAsXML

@Deprecated
public String getAsXML()

Deprecated.

Returns the data of the dataset as a Base64-encoded zipped XML string

convertToQualityCodes

protected static QualityCode[][] convertToQualityCodes(DataQuality[][] dataQualities)
