Method Summary

Modifier and Type	Method	Description
protected String	psThreadCommand()	Returns the ps command (without the trailing -p <pid>) used to enumerate this process's threads when refreshing a single thread.
protected List<BsdPsThreadKeyword>	psThreadKeywords()	Returns this platform's ordered ps thread column keys, used to parse thread rows positionally.

Modifier and Type	Method	Description
long	getContextSwitches()	A snapshot of the context switches the thread has done.
long	getKernelTime()	Kernel (privileged) time used by the thread.
long	getMajorFaults()	The number of major (hard) faults the thread has made which have required loading a memory page from disk.
long	getMinorFaults()	The number of minor (soft) faults the thread has made which have not required loading a memory page from disk.
String	getName()	The name of the thread.

Field Details

PS_THREAD_KEYWORDS

public static final List<BsdPsThreadKeyword> PS_THREAD_KEYWORDS

Ordered ps thread columns. Shared with FreeBsdOSProcess's thread enumeration so the column list and parsing stay in lockstep. PRI must remain last (the row-complete sentinel).

PS_THREAD_COLUMNS

public static final String PS_THREAD_COLUMNS
