public boolean isSubReportExecutable()

returnFromSubReport

public ProcessState returnFromSubReport(LayoutProcess layoutProcess)
                                 throws ReportProcessingException

Throws:

ReportProcessingException

restart

public ProcessState restart()
                     throws ReportProcessingException

Throws:

ReportProcessingException

getErrorHandler

public ReportProcessingErrorHandler getErrorHandler()

Specified by:

getErrorHandler in interface ReportState

setErrorHandler

public void setErrorHandler(ReportProcessingErrorHandler errorHandler)

Specified by:

setErrorHandler in interface ReportState

setSequenceCounter

public void setSequenceCounter(int sequenceCounter)

getSequenceCounter

public int getSequenceCounter()

getCurrentSubReportMarker

public InlineSubreportMarker getCurrentSubReportMarker()

Specified by:

getCurrentSubReportMarker in interface ReportState

isInlineProcess

public boolean isInlineProcess()

Specified by:

isInlineProcess in interface ReportState

getSubreportProcessingType

Specified by:

clone in interface ReportState

Overrides:

clone in class Object

Throws:

CloneNotSupportedException

getAdvanceHandler

setAdvanceHandler

public void setAdvanceHandler(AdvanceHandler advanceHandler)

advance

public final ProcessState advance()
                           throws ReportProcessingException

Throws:

                          throws ReportProcessingException

Throws:

ReportProcessingException
