Interface FileDigest

public interface FileDigest

The FileDigest interface specifies the nescessary information to determine if a file on disk has changed from some checkpoint. There are three pieces of information that can be used to determine this: the file's lastModified time, the file size, and a checksum of the file's contents.

Method Summary

MD5	getFileMD5() Gets the MD5 cryptographic hash of the file's content.
long	getFileSize() Gets the file's size.
double	getFileTime() Gets the file's last modified time.
void	setFileMD5(MD5 md5) Sets the MD5 cryptographic hash of the file's content.
void	setFileSize(long size) Sets the file's size.
void	setFileTime(double time) Sets the file's last modified time.

Method Detail

getFileTime

public double getFileTime()

Gets the file's last modified time. Follows Microsoft's COLEDateTime specification, which is the number of days from midnight, 30 December 1899, in UTC.

Returns:

The file's last modified time, as the number days from midnight, 30 December 1899, in UTC.

setFileTime

public void setFileTime(double time)

Sets the file's last modified time.

Parameters:

time - The file's last modified time, as the number days from midnight, 30 December 1899, in UTC.

getFileSize

public long getFileSize()

Gets the file's size. This is returned as a long (8 bytes) because an int (4 bytes) can only support file sizes up to roughly 2.1GB.

Returns:

The file's size, in bytes.

setFileSize

public void setFileSize(long size)

Sets the file's size.

Parameters:

size - The file's size, in bytes.

getFileMD5

public MD5 getFileMD5()

Gets the MD5 cryptographic hash of the file's content. See RFC1321.

Returns:

The MD5 cryptographic hash of the file's content.

setFileMD5

public void setFileMD5(MD5 md5)

Sets the MD5 cryptographic hash of the file's content.

Parameters:

md5 - The MD5 cryptographic hash of the file's content.
