WorkDuration


public final class WorkDuration
extends Object

java.lang.Object
   ↳ 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.

Public methods

equals

Added in API level 35
public boolean equals (Object obj)

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 return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

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 Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getActualCpuDurationNanos

Added in API level 35
public long getActualCpuDurationNanos ()

Returns the actual CPU duration in nanoseconds. All timings should be in SystemClock#uptimeNanos().

Returns
long

getActualGpuDurationNanos

Added in API level 35
public long getActualGpuDurationNanos ()

Returns the actual GPU duration in nanoseconds. All timings should be in SystemClock#uptimeNanos().

Returns
long

getActualTotalDurationNanos

Added in API level 35
public long getActualTotalDurationNanos ()

Returns the actual total duration in nanoseconds. All timings should be in SystemClock#uptimeNanos().

Returns
long

getWorkPeriodStartTimestampNanos

Added in API level 35
public long getWorkPeriodStartTimestampNanos ()

Returns the work period start timestamp based in nanoseconds. All timings should be in SystemClock#uptimeNanos().

Returns
long

hashCode

Added in API level 35
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by 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 hashCode method must consistently return the same integer, provided no information used in equals comparisons 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 equals method, then calling the hashCode method 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 equals method, then calling the hashCode method 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.

Returns
int a hash code value for this object.
