FileCompressionMethod Property
This property specifies the compression method used for the individual file.
Syntax
sevenzip.getFileCompressionMethod(index, [callback]) sevenzip.setFileCompressionMethod(index, fileCompressionMethod, [callback])
Possible Values
0 (cmszLzma), 1 (cmszBzip2), 2 (cmszDelta), 3 (cmszCopy), 4 (cmszDeflate), 5 (cmszLzma2)
Default Value
0
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for the getFileCompressionMethod([callback]) method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
The callback for the setFileCompressionMethod([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This property specifies the compression method used for the individual file. The compression method set here is applicable to this file only. Possible values are:
Value | Method |
cmszLzma (0 - default) | LZMA |
cmszBzip2 (1) | BZip2 |
cmszDelta (2) | Delta |
cmszCopy (3) | Copy (no compression) |
cmszDefalte (4) | Deflate |
cmszDefalte (5) | LZMA2 |
If this property is not set, the method specified by the CompressionMethod property will be used. Note that different files in the archive may use different compression methods.
The size of the array is controlled by the FileCount property.
This property is not available at design time.
