TransferDataSetManagerProvider

Background and Use Cases

FineReport traditionally requires local design before deployment to a server. For users without remote design capabilities, managing data connections and server-side datasets involves repetitive manual operations. Version 10.0 introduced dataset import/export functionality, and this interface enables custom dataset plugins to also support import/export.

Interface Definition

package com.fr.decision.fun;

import com.fr.stable.fun.mark.Mutable;

public interface TransferDataSetManagerProvider<T extends TableData>
        extends Mutable, TransferDataSetManager<T> {

    String XML_TAG = "TransferDataSetManagerProvider";
    int CURRENT_LEVEL = 1;
}

package com.fr.decision.webservice.v10.datasource.dataset.manage;

public interface TransferDataSetManager<T extends TableData> {

    Class<? extends TableData> getDataSetClass();

    String serialize(T t);

    T deserialize(String str);

    String[] getDependencyPaths(T t);
}

Supported Versions

Plugin Registration

Add the following node to plugin.xml:

<extra-decision>
    <TransferDataSetManagerProvider class="your class name"/>
</extra-decision>

How It Works

TransferDataSetFactory maintains a registry mapping dataset classes to their managers. For serialization, you can reuse existing readXML/writeXML implementations:

GeneralXMLTools.writeXMLableAsString(ds)
GeneralXMLTools.readStringAsXMLable(config, ds)

The getDependencyPaths method returns only the file paths required by the dataset's dependencies during export.
