FileContentEditorProvider

Background and Use Cases

This interface is used to modify frontend functionality in FanRuan products that lacks standard plugin interfaces. Common use cases include: chart JS modifications, widget UI adjustments, and business event tracking injection.

Interface Definition

package com.fr.stable.fun;

import com.fr.stable.fun.mark.Mutable;
import com.fr.web.file.RequestFileGroup;
import com.fr.web.file.RequestFileSource;

public interface FileContentEditorProvider extends Mutable {

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

    boolean accept(RequestFileSource fileSource);
    String modify(RequestFileSource fileSource);
    boolean accept(RequestFileGroup fileGroup);
    String compose(RequestFileGroup fileGroup, String separator);
}

• RequestFileSource: Contains content, path, and HttpServletRequest attributes, with getter/setter methods and a static factory method build
• RequestFileGroup: Manages a list of RequestFileSource objects, providing methods to retrieve file sources, check format availability, and concatenate content

Supported Versions

Plugin Registration

Add the following node in plugin.xml:

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

How It Works

This interface intercepts resource file requests (op=emb, op=resource, /file paths). It retrieves registered provider instances via PluginModule to apply modifications to JS/CSS content.
