WorkDuration
class WorkDuration
| kotlin.Any | |
| ↳ | android.os.WorkDuration |
WorkDuration contains the measured time in nano seconds of the workload in each component, see PerformanceHintManager.Session.reportActualWorkDuration(WorkDuration). All timings should be in SystemClock.uptimeNanos() and measured in wall time.

equals
fun equals(other: Any?): Boolean
Indicates whether some other object is "equal to" this one.
The equals method implements an equivalence relation on non-null object references:
- It is reflexive: for any non-null reference value
x,x.equals(x)should returntrue. - It is symmetric: for any non-null reference values
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value
x,x.equals(null)should returnfalse.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters | |
|---|---|
obj |
the reference object with which to compare. |
| Return | |
|---|---|
Boolean |
true if this object is the same as the obj argument; false otherwise. |
getActualCpuDurationNanos
fun getActualCpuDurationNanos(): Long
Returns the actual CPU duration in nanoseconds. All timings should be in SystemClock.uptimeNanos().
getActualGpuDurationNanos
fun getActualGpuDurationNanos(): Long
Returns the actual GPU duration in nanoseconds. All timings should be in SystemClock.uptimeNanos().
getActualTotalDurationNanos
fun getActualTotalDurationNanos(): Long
Returns the actual total duration in nanoseconds. All timings should be in SystemClock.uptimeNanos().
getWorkPeriodStartTimestampNanos
fun getWorkPeriodStartTimestampNanos(): Long
Returns the work period start timestamp based in nanoseconds. All timings should be in SystemClock.uptimeNanos().
hashCode
fun hashCode(): Int
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.
The general contract of hashCode is:
- Whenever it is invoked on the same object more than once during an execution of a Java application, the
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equalsmethod, then calling thehashCodemethod on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal according to the
equalsmethod, then calling thehashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
| Return | |
|---|---|
Int |
a hash code value for this object. |
