getDataDefinitionsForGrouping(Series series)
Provides a list of data definitions for grouping. |
java.lang.String |
getExpectedStringFormat()
|
java.util.Locale |
getLocale()
Deprecated. use getULocale() instead. |
java.lang.Object |
getMaximum(DataSet ds)
Causes implementation specific data set processor classes to compute the maximum value in a data set of a specific series type. |
java.lang.Object |
getMinimum(DataSet ds)
Causes implementation specific data set processor classes to compute the minimum value in a data set of a specific series type. |
com.ibm.icu.util.ULocale |
getULocale()
Provides the locale to device renderer implementations as needed to retrieve localized resources for presentation. |
DataSet |
populate(java.lang.Object oResultSetDef,
DataSet ds)
Populates a data set with data element values retrieved from a result set created as a result of query execution |
java.lang.String |
toString(java.lang.Object[] columnData)
Attempts to format a column of data to string. |

DataSet fromString(java.lang.String sDataSetRepresentation, DataSet ds) throws ChartException
sDataSetRepresentation
- A line of text containing a list of data element values that
may be parsed.ds
- An existing data set (or null for a new one) that needs to be
filled with data elements created by parsing the line of text
as per the expected string format.
ChartException
java.lang.String toString(java.lang.Object[] columnData) throws ChartException
columnData
- array of column data. All elements have same class type.
ChartException
java.lang.String getExpectedStringFormat()
DataSet populate(java.lang.Object oResultSetDef, DataSet ds) throws ChartException
oResultSetDef
- An instance of a generic result set that is host application
specific. For BIRT, the result set class is ResultSetDataSetds
- An existing data set (or null for a new one) that needs to be
filled with with data elements extracted from the result set
definition
ChartException
java.lang.Object getMinimum(DataSet ds) throws ChartException
ds
- The data set for which the minimum value needs to be computed
ChartException
java.lang.Object getMaximum(DataSet ds) throws ChartException
ds
- The data set for which the maximum value needs to be computed
ChartException
java.util.Locale getLocale()
getULocale()
instead.
