@Override
    public String getFormattedContent(int indentLevel, CompilationUnit compilationUnit) {
        return this.innerInterface.getFormattedContent(indentLevel, compilationUnit);
    }
@Override
    public String getFormattedContent(int indentLevel, CompilationUnit compilationUnit) {
        return this.innerInterface.getFormattedContent(indentLevel, compilationUnit);
    }
重写获取Java内容方法，调用InnerInterface的实现

@param indentLevel
@param compilationUnit
@return
