Define maximum zip file size

Globally

If many file attachments are to be exported, the created zip archive could be very large. That's why it's possible to configure the maximum file size globally:

plugin_customization.ini: define maximum zip file size globally

# Defines the maximum size of zip file for export. If there are too many media asset images to export, then several zip files may be
# exported, but each zip file can not be over this threshold.
# Default is 2147483648. ( = 2^31 = 2 gigabyte)
com.heiler.ppm.mediaasset.server/export.maxZipFileSize = 2147483648

Export template specific

Sometimes, the global maximum zip file size definition is not sufficient. The integration of various web shops may require more configuration options.

Since PIM 7.0.05.14 and 7.1.01.00, you can use a new programmatical way to set the maximum zip file size for a single export template.

Implement a custom export function that can set the maximum zip file size to the mime export context:

Custom export function to set maximum zip file size

public class SetZipFileSizeFunction extends FunctionBaseImpl
{
  public SetZipFileSizeFunction()
  {
    super( "SetZipFileSize" );
    // TODO set function description
  }
  @Override
  public int getMinParameterCount()
  {
    return 1;
  }
  @Override
  public int getMaxParameterCount()
  {
    return 1;
  }
  @Override
  public Object execute( Object[] parameters, Map context ) throws CoreException
  {
    if ( parameters != null && parameters.length == 1 && context != null )
    {
      // TODO handle ConversionException
      Long maxFileSizeToSet = ConvertUtils.getInstance()
                                          .convert( parameters[ 0 ], Long.class );
      // TODO check context: not null, mimeExportInfo not null
      MimeExportInfo mimeExportInfo = ( MimeExportInfo ) context.get( MimeExportInfo.MIME_EXPORT_INFO );
      mimeExportInfo.setOptionMaxZipFileSize( maxFileSizeToSet );
      // no output
      return StringUtils.EMPTY;
    }
    String message = StringUtils.replace( Messages.getString( "function.error.wrongparams" ), "{functionname}", //$NON-NLS-1$ //$NON-NLS-2$
                                          this.name );
    IStatus status = new StatusExt( Categories.SYSTEM, IStatus.ERROR, ExportCorePlugin.PLUGIN_ID,
                                    ExportErrorCodes.ERR_EXPORT_FCT_WRONG_PARAM_COUNT, message, null );
    throw new CoreException( status );
  }
}

Call the custom export function once in an export template:

Export template: call custom function once

{?SetZipFileSize "52428800"} {! 50 MB = 52428800 Bytes}
