public WindowsOSThread(int pid,
 int tid,
 String procName,
 ThreadPerformanceData.PerfCounterBlock pcb)

Method Details

getThreadId

public int getThreadId()

Description copied from interface: OSThread

The thread id. The meaning of this value is OS-dependent.

Returns:

Returns the id of the thread.

getName

public String getName()

Description copied from interface: OSThread

The name of the thread. Presence of a name is operating-system dependent and may include information (such as an index of running threads) that changes during execution.

Returns:

Returns the name of the task/thread.

getState

public OSProcess.State getState()

Description copied from interface: OSThread

Gets the execution state of the task/thread.

Returns:

Returns the execution state of the task/thread.

getStartMemoryAddress

public long getStartMemoryAddress()

Description copied from interface: OSThread

The memory address above which this thread can run.

Returns:

The start address.

getContextSwitches

public long getContextSwitches()

Description copied from interface: OSThread

A snapshot of the context switches the thread has done. Since the context switches could be voluntary and non-voluntary, this gives the sum of both.

Not available on AIX.

Returns:

sum of both voluntary and involuntary context switches.

getKernelTime

public long getKernelTime()

Description copied from interface: OSThread

Kernel (privileged) time used by the thread.

Returns:

Returns the number of milliseconds the task/thread has executed in kernel/system mode.

getUserTime

public long getUserTime()

Description copied from interface: OSThread

User time used by the thread.

Returns:

Returns the number of milliseconds the task/thread has executed in user mode.

getStartTime

public long getStartTime()

Description copied from interface: OSThread

The start time of the thread.

Returns:

Returns the start time of the task/thread in number of milliseconds since January 1, 1970.

getUpTime

public long getUpTime()

Description copied from interface: OSThread

Elapsed/up-time of the thread.

Returns:

Returns the number of milliseconds since the task/thread started.

getPriority

public int getPriority()

Description copied from interface: OSThread

Priority of the thread, the meaning of which is dependent on the OS.

Returns:

priority.

updateAttributes

public boolean updateAttributes()

Description copied from interface: OSThread

Attempts to updates process attributes. Returns false if the update fails, which will occur if the process no longer exists. Not implemented for macOS, as thread ID is simply an index and not unique.

Returns:

true if the update was successful, false if the update failed. In addition, on a failed update the thread state will be changed to OSProcess.State.INVALID.
