XTMFragmentExporter

public XTMFragmentExporter(String tmid)

Method Detail

setLocatorHandler

public void setLocatorHandler(XTMFragmentExporter.LocatorHandlerIF locator_handler)

EXPERIMENTAL: Sets the locator handler. Currently only used for occurrences.

setUseLocalIds

public void setUseLocalIds(boolean use_local_ids)

PUBLIC: Controls whether or not internal references of the form '#id' will be used. TMRAP cannot use this, whereas when self-contained XTM fragment files are produced this should be used.

getUseLocalIds

public boolean getUseLocalIds()

PUBLIC: Whether or not internal references of the form '#id' will be exported.
