Method Detail

getOwningProcessId

public int getOwningProcessId()

Description copied from interface: OSThread

The owning process of this thread. For single-threaded processes, the owning process ID may be the same as the thread's ID.

Specified by:

getOwningProcessId in interface OSThread

Returns:

The owning process of this thread.

getThreadCpuLoadCumulative

public double getThreadCpuLoadCumulative()

Description copied from interface: OSThread

Gets cumulative CPU usage of this thread.

Specified by:

getThreadCpuLoadCumulative in interface OSThread

Returns:

The proportion of up time that the thread was executing in kernel or user mode.

queryCumulativeCpuLoad

private double queryCumulativeCpuLoad()

getThreadCpuLoadBetweenTicks

public double getThreadCpuLoadBetweenTicks(OSThread priorSnapshot)

Description copied from interface: OSThread

Gets CPU usage of this thread since a previous snapshot of the same thread, provided as a parameter.

Specified by:

getThreadCpuLoadBetweenTicks in interface OSThread

Parameters:

priorSnapshot - An OSThread object containing statistics for this same thread collected at a prior point in time. May be null.

Returns:

If the prior snapshot is for the same thread at a prior point in time, the proportion of elapsed up time between the current thread snapshot and the previous one that the thread was executing in kernel or user mode. Returns cumulative load otherwise.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
