FileInfo

public FileInfo(org.w3c.dom.Element elem)
         throws java.lang.Exception

Construct a 'FileInfo' object from the information contained in the org.w3c.dom.Element object.

Parameters:

elem - org.w3c.dom.Element object

Throws:

java.lang.Exception

FileInfo

public FileInfo(java.lang.String name,
        oracle.lite.web.ifs.OSFile file)

Construct a FileInfo object from a 'Oracle Lite File' object.

Parameters:

name - File name

file - oracle.lite.web.ifs.OSFile object.

Method Detail

copyTo

public void copyTo(java.io.OutputStream out)
            throws java.io.IOException

Copy data from the file to the OutputStream

Parameters:

out - OutputStream object.

Throws:

java.io.IOException

java.io.IOException

exists

public boolean exists()

Check if the file actually exists in the file system.

Returns:

true of file exists, false otherwise

getFile

public oracle.lite.web.ifs.OSFile getFile()

Get the file as an oracle.lite.web.ifs.OSFile object

Returns:

oracle.lite.web.ifs.OSFile object

getInputStream

public java.io.InputStream getInputStream()
                                   throws java.io.IOException

Return an InputStream after skipping 'skip' bytes

Returns:

InputStream to the file, offset by 'skip' bytes

Throws:

java.io.IOException

getLastModified

public java.lang.String getLastModified()

Get the time the file was last modified.

Returns:

last modified time.

getLength

public int getLength()

Return actual number of bytes after skipping 'skip' number of bytes from the file.

Returns:

length of file minus 'skip' bytes

getMetaData

public byte[] getMetaData()

Return file meta data information as an array of bytes.

Returns:

byte array containing file meta data

getName

public java.lang.String getName()

Get the name of the file

Returns:

File name

getSize

public java.lang.String getSize()

Get the size of the file

Returns:

File size

getTotalSize

public int getTotalSize()

Return the total size of the file (File size + meta data size).

Returns:

total file size

getVersion

public java.lang.String getVersion()

Get the version of the file

Returns:

File version

isSame

public boolean isSame(FileDiff fd)

Check if the file has been modified or not using file size and file modified time. In order to compensate for the 'day light saving' time bug in 5.0.2.10.0 version of Oracle Lite client, last modified times are considered to be same if the difference is within an hour.

Parameters:

fd - oracle.lite.dm.FileDiff

Returns:

false if the file has been modified, true otherwise. Vino: Fix for Bug 5474125 - UPDATE.EXE NOT DOWNLOAD NEW FILE AFTER NETWORK ERROR The old logic did a CRC check only if the file sizes were different. In the cases, where the updated file on the server also had the same file size, update did not bring it down. Now a CRC check is a must. If same, check for file size and then decide whether to bring it down or not.

lastModified

public java.sql.Timestamp lastModified()

Get the time the file was last modified as java.sql.Timestamp.

Returns:

last modified time as java.sql.Timestamp.

setActualName

public void setActualName(java.lang.String name)

Parameters:

name - Actual filename

setLastModified

public void setLastModified(java.lang.String mod)

Set a new last modified time.

Parameters:

mod - new modified time

setSize

public void setSize(java.lang.String size)

Set a new file size.

Parameters:

size - New file size
