  org.eclipse.birt.report.engine.api.ReportEngine

All Implemented Interfaces:

IReportEngine

public class ReportEngine

extends java.lang.Object

implements IReportEngine

This is a wrapper class for the IReportEngine. The new user should use the IReportEngineFactory to create the IReportEngine instead of use this class directly.

protected IReportEngine engine

Constructor Detail

ReportEngine

public ReportEngine(EngineConfig config)

Constructor. If config is null, engine derives BIRT_HOME from the location of the engine jar file, and derives data driver directory as $BIRT_HOME/drivers. For a simple report with no images and links, engine will run without complaining. If the report has image/chart defined, the engine has to be configured with relevant image and chart handlers.

Parameters:

config - an engine configuration object used to configure the engine

Method Detail

getRootScope

public java.lang.Object getRootScope()

get the root scope used by the engine

Specified by:

getRootScope in interface IReportEngine

Returns:

changeLogLevel

public void changeLogLevel(java.util.logging.Level newLevel)

Change the log level to newLevel

Specified by:

changeLogLevel in interface IReportEngine

Parameters:

newLevel - - new log level

getConfig

returns the engine configuration object

Specified by:

getConfig in interface IReportEngine

Returns:

the engine configuration object
