Method Detail

addField

public void addField(java.lang.Object field,
                     Column.CellFormatter formatter)
              throws java.io.IOException

Description copied from interface: TableOutputGenerator

Adds a new cell to the output.

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Description copied from interface: TableOutputGenerator

Informs the generator that the data is completely processed.

Throws:

java.io.IOException

getFormats

public java.lang.String[] getFormats()

Returns:

The generator's format

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 #initialize(OutputStream, TableDefinition, boolean, TableReport, TableReport, CellFormatter[], ParameterSet, User, ReportExecutionConfig...) the CompiledReport object should not contain actual report data.

Returns:

The finished report

initialize

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

java.io.IOException

nextRow

public void nextRow()
             throws java.io.IOException

Description copied from interface: TableOutputGenerator

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

Throws:

java.io.IOException

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.
