Constructor Detail

DesignEngineImpl

public DesignEngineImpl(DesignConfig config)

Constructs a DesignEngine with the given platform config.

Parameters:

config - the platform config.

Method Detail

newSessionHandle

public SessionHandle newSessionHandle(com.ibm.icu.util.ULocale locale)

Creates a new design session handle. The application uses the handle to open, create and manage designs. The session also represents the user and maintains the user's locale information.

Specified by:

newSessionHandle in interface IDesignEngine

Parameters:

locale - the user's locale. If null, uses the system locale.

Returns:

the design session handle

getMetaData

public IMetaDataDictionary getMetaData()

Gets the meta-data of the design engine.

Specified by:

getMetaData in interface IDesignEngine

Returns:

the meta-data of the design engine.

registerMetaLogger

public void registerMetaLogger(IMetaLogger newLogger)

Registers a IMetaLogger to record initialization errors. The logger will be notified of the errors during meta-data initialization. The meta-data system will be initialized once (and only once). Loggers should be registered before the first time a session is created so that it can be notified of the logging actions.

Specified by:

registerMetaLogger in interface IDesignEngine

Parameters:

newLogger - the MetaLogger to be registered.

removeMetaLogger(IMetaLogger)

removeMetaLogger

public boolean removeMetaLogger(IMetaLogger logger)

Removes a IMetaLogger. This method will remove the logger from the list and close the logger if it has already been registered. The logger will no longer be notified of the errors during metadata initialization. Returns true if this logger manager contained the specified logger.

Specified by:

removeMetaLogger in interface IDesignEngine

Parameters:

logger - the MetaLogger to be removed.

Returns:

true if this logger manager contained the specified logger.
