7Zip解压支持库,
支持LZMA/BCJ*算法

创建7Zip解压对象

sevenZip.decoder2()

创建7Zip解压对象,

返回对象:sevenZipDecoder2Object

sevenZipDecoder2Object 成员列表

sevenZipDecoder2Object.close()

关闭对象

sevenZipDecoder2Object.count()

返回文件数

sevenZipDecoder2Object.each()

for path,isDir,time,size64 in sevenZipDecoder2Object.each(){
    /*遍历压缩包中的所有文件或目录,  
path 参数为相对路径,  
isDir 参数指定当前路径是否目录,  
time 参数为文件修改时间,  
size64 参数为文件大小，math.size64 对象*/
}

sevenZipDecoder2Object.extract("解压路径")

解压文件到指定目录,
目录不存在则自动创建该目录

sevenZipDecoder2Object.extractPrepareOperation

sevenZipDecoder2Object.extractPrepareOperation = function(askExtractMode,itemIndex,filepath,isDir){
    /*准备解压时回调此函数,filepath参数为当前解压的文件路径*/
}

sevenZipDecoder2Object.extractSetCompleted

sevenZipDecoder2Object.extractSetCompleted = function(lowSize,hiSize,percent){
    io.print("已解压",math.formatSize(lowSize,hiSize)," %" + percent )
    /*解压完成时回调此函数,percent为表示解压进度的百分比数值*/
}

sevenZipDecoder2Object.extractSetOperationResult

sevenZipDecoder2Object.extractSetOperationResult = function(opRet){
    /*这里可以获取操作结果*/
    if( opRet == 0/*kOK*/ ){

    }
    elseif( opRet == 1/*kUnSupportedMethod*/ ){
        io.print("Unsupported Method")
    }
    elseif( opRet == 0/*kDataError*/ ){
        io.print("CRC Failed")
    }
    elseif( opRet == 0/*kCRCError*/ ){
        io.print("Data Error")
    }
    else {
        io.print("Unknown Error")
    }
}

sevenZipDecoder2Object.extractSetTotal

sevenZipDecoder2Object.extractSetTotal = function(lowSize,hiSize){
    var size64 = math.size64(lowBytes,hiBytes);
    io.print("压缩包大小",size64.format() )
    /*返回 _S_FALSE 取消解压*/
}

sevenZipDecoder2Object.getItemBoolean(文件索引,_kpid)

文件索引自1开始,返回属性布尔值
参数2使用_kpid前缀的常量表示属性索引

sevenZipDecoder2Object.getItemNumber(文件索引,_kpid)

文件索引自1开始,返回属性数值
参数2使用_kpid前缀的常量表示属性索引

sevenZipDecoder2Object.getItemSize64()

返回对象:mathSize64Object

sevenZipDecoder2Object.getItemSize64(文件索引,_kpidSize)

文件索引自1开始,返回文件大小

sevenZipDecoder2Object.getItemString(文件索引,_kpid)

文件索引自1开始,返回属性字符串值
参数2使用_kpid前缀的常量表示属性索引

sevenZipDecoder2Object.getItemTime(文件索引,_kpid)

文件索引自1开始,返回属性时间值
参数2使用_kpid前缀的常量表示属性索引

sevenZipDecoder2Object.open("7z压缩包路径",是否测试模式)

打开压缩包,
成功返回true,失败返回false以及错误信息

sevenZipDecoder2Object.openSetCompleted

sevenZipDecoder2Object.openSetCompleted = function(files,lowBytes,hiBytes,percent){
    io.print("已打开",math.size64(lowBytes,hiBytes).format() ," %" + percent)
    /*打开压缩包回调此函数,percent为表示打开进度的百分比数值*/
}

sevenZipDecoder2Object.openSetTotal

sevenZipDecoder2Object.openSetTotal = function(files,lowBytes,hiBytes){
    var size64 = ..math.size64(lowBytes,hiBytes);
    /*返回 _S_FALSE 取消解压*/
}

sevenZipDecoder2Object.printError

sevenZipDecoder2Object.printError = function(name,message){
    /*解压时调用此函数显示错误信息*/
    io.print("出错了", name,message ) 
}

sevenZipDecoder2Object.size64()

返回解压后大小

返回对象:mathSize64Object
