Method Summary

Modifier and Type	Method	Description
void	addField(Object field, Column.CellFormatter formatter)	Adds a new cell to the output.
void	addGroupRow(int[] subtotalIndices, Object[] subtotals, int[] subtotalGroupFieldIndices, Object[] subtotalGroupFieldValues, int rowSize, Column.CellFormatter[] cellFormatters)	In case a report is exported using subtotals, this method is called whenever a group is finished and an aggregation row needs to be added.
void	close()	Informs the generator that the data is completely processed.
CompiledReport	getFormatInfo()	Returns an empty CompiledReport object to specify the type of report that is generated by this generator.
String[]	getFormats()
CompiledReport	getTableObject()	Is called upon completion to get the final report object.
void	initialize(OutputStream os, TableDefinition td, boolean withSubtotals, TableReport report, TableReport originalReport, Column.CellFormatter[] cellFormatters, ParameterSet parameters, User user, ReportExecutionConfig... configs)	Initializes the generator before the first data point is provided.
boolean	isCatchAll()	Returns true if this generator should be used if the format is not recognized.
void	nextRow()	Informs the generator that the current data row is finished and a new row is about to begin

public RSTableOutputGenerator()

Method Details

getFormats

public String[] getFormats()

Returns:

The generator's format

initialize

public void initialize(OutputStream os,
 TableDefinition td,
 boolean withSubtotals,
 TableReport report,
 TableReport originalReport,
 Column.CellFormatter[] cellFormatters,
 ParameterSet parameters,
 User user,
 ReportExecutionConfig... configs)
                throws IOException

Description copied from interface: TableOutputGenerator

Initializes the generator before the first data point is provided.

Specified by:

initialize in interface TableOutputGenerator

Overrides:

initialize in class TableOutputGeneratorImpl

Parameters:

os - The output stream to be used. If no output stream is provided (the object is null), then the report should be generated in memory.

Throws:

IOException

nextRow

public void nextRow()

Description copied from interface: TableOutputGenerator

Informs the generator that the current data row is finished and a new row is about to begin

addField

public void addField(Object field,
 Column.CellFormatter formatter)

Description copied from interface: TableOutputGenerator

Adds a new cell to the output.

Parameters:

field -

formatter -

close

public void close()

Description copied from interface: TableOutputGenerator

Informs the generator that the data is completely processed.

getTableObject

public CompiledReport getTableObject()

Description copied from interface: TableOutputGenerator

Is called upon completion to get the final report object. In case an outputstream is used (see TableOutputGenerator.initialize(OutputStream, TableDefinition, boolean, TableReport, TableReport, CellFormatter[], ParameterSet, User, ReportExecutionConfig...) the CompiledReport object should not contain actual report data.

Returns:

The finished report

getFormatInfo

public CompiledReport getFormatInfo()

Description copied from interface: ReportOutputGenerator

Returns an empty CompiledReport object to specify the type of report that is generated by this generator.

isCatchAll

public boolean isCatchAll()

Description copied from interface: ReportOutputGenerator

Returns true if this generator should be used if the format is not recognized.

Specified by:

isCatchAll in interface ReportOutputGenerator

Overrides:

isCatchAll in class TableOutputGeneratorImpl

addGroupRow

public void addGroupRow(int[] subtotalIndices,
 Object[] subtotals,
 int[] subtotalGroupFieldIndices,
 Object[] subtotalGroupFieldValues,
 int rowSize,
 Column.CellFormatter[] cellFormatters)

Description copied from interface: TableOutputGenerator

In case a report is exported using subtotals, this method is called whenever a group is finished and an aggregation row needs to be added.

Specified by:

addGroupRow in interface TableOutputGenerator

Overrides:

addGroupRow in class TableOutputGeneratorImpl
