TableDataBuildProvider

Background and Use Cases

This interface is suited for dataset execution monitoring and transformation scenarios — for example, converting large numbers of the same dataset type into a more optimized and secure dataset type for computation, or implementing unified parameter pre-processing and execution monitoring across all datasets.

Interface Definition

package com.fr.stable.fun;

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

public interface TableDataBuildProvider<T extends TableData> extends Mutable {

    int CURRENT_LEVEL = 1;
    String MARK_STRING = "TableDataBuildProvider";

    boolean matchPattern(String tdClassName);
    Class<? extends TableData> getAttrClass();
    Class<T> getBuildClass();
    T newInstance() throws Exception;
}

Supported Versions

Plugin Registration

Add the following node in plugin.xml:

<extra-core>
    <TableDataBuildProvider class="your class name"/>
</extra-core>

How It Works

This interface takes effect during the XML-to-object deserialization process when a template file loads its dataset configuration. The system retrieves all registered dataset conversion providers, identifies datasets that need transformation via matchPattern, then calls newInstance to create a new dataset instance.
