Method Details

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 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

getDisks

public static List<HWDiskStore> getDisks()

Gets the disks on this machine

Returns:

a list of HWDiskStore objects representing the disks
