Class SolarisHWDiskStore

java.lang.Object

oshi.hardware.common.AbstractHWDiskStore

oshi.hardware.common.platform.unix.solaris.SolarisHWDiskStore

All Implemented Interfaces:

HWDiskStore

@ThreadSafe
public abstract class SolarisHWDiskStore
extends AbstractHWDiskStore

Abstract base for Solaris HWDiskStore. The disk enumeration (getDisks(SolarisHWDiskStore.DiskStoreFactory)) and partition assembly are shared and call the common iostat/lshal/prtvtoc drivers; the kstat-based per-disk I/O stats are native and fetched by the JNA and FFM subclasses via queryStats().

Method Details

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

protected static List<HWDiskStore> getDisks(SolarisHWDiskStore.DiskStoreFactory factory)

Gets the disks on this machine, building each store with the given concrete factory.

Parameters:

factory - creates the platform-specific store instances

Returns:

a list of HWDiskStore objects representing the disks

queryStats

protected abstract SolarisHWDiskStore.DiskStats queryStats()

Looks up this disk's per-disk I/O stats from the subclass's kstat data source.

Returns:

stats POJO, or null if no entry was found for this disk name
