Method Detail

getDisks
public static java.util.List<HWDiskStore> getDisks()
Gets the disks on this machine.- Returns:
- a list of
HWDiskStore
objects representing the disks
-
getReads
public long getReads()
Description copied from interface:HWDiskStore
The number of reads from the disk- Returns:
- the reads
-
getReadBytes
public long getReadBytes()
Description copied from interface:HWDiskStore
The number of bytes read from the disk- Returns:
- the bytes read
-
getWrites
public long getWrites()
Description copied from interface:HWDiskStore
The number of writes to the disk- Returns:
- the writes
-
getWriteBytes
public long getWriteBytes()
Description copied from interface:HWDiskStore
The number of bytes written to the disk- Returns:
- the bytes written
-
getCurrentQueueLength
public long getCurrentQueueLength()
Description copied from interface:HWDiskStore
The length of the disk queue (#I/O's in progress). Includes I/O requests that have been issued to the device driver but have not yet completed. Not supported on macOS.- Returns:
- the current disk queue length
-
getTransferTime
public long getTransferTime()
Description copied from interface:HWDiskStore
The time spent reading or writing, in milliseconds.- Returns:
- the transfer time
-
getTimeStamp
public long getTimeStamp()
Description copied from interface:HWDiskStore
The time this disk's statistics were updated.- Returns:
- the timeStamp, in milliseconds since the epoch.
-
getPartitions
public java.util.List<HWPartition> getPartitions()
Description copied from interface:HWDiskStore
The partitions on this disk.- Returns:
- an
UnmodifiableList
of the partitions on this drive.
-
updateAttributes
public boolean updateAttributes()
Description copied from interface:HWDiskStore
Make a best effort to update all the statistics about the drive without needing to recreate the drive list. This method provides for more frequent periodic updates of individual drive statistics but may be less efficient to use if updating all drives. It will not detect if a removable drive has been removed and replaced by a different drive in between method calls.- Returns:
- True if the update was (probably) successful, false if the disk was not found
