Public constructors

DataStallReport

public DataStallReport (Network network, 
                long reportTimestamp, 
                int detectionMethod, 
                LinkProperties linkProperties, 
                NetworkCapabilities networkCapabilities, 
                PersistableBundle stallDetails)

Constructor for DataStallReport.

Apps should obtain instances through ConnectivityDiagnosticsCallback#onDataStallSuspected instead of instantiating their own instances (unless for testing purposes).

Parameters
`network`	`Network`: The Network for which this DataStallReport applies This value cannot be `null`.
`reportTimestamp`	`long`: The timestamp for the report
`detectionMethod`	`int`: The detection method used to identify this data stall Value is `DETECTION_METHOD_DNS_EVENTS`, or `DETECTION_METHOD_TCP_METRICS`
`linkProperties`	`LinkProperties`: The LinkProperties available on network at reportTimestamp This value cannot be `null`.
`networkCapabilities`	`NetworkCapabilities`: The NetworkCapabilities available on network at reportTimestamp This value cannot be `null`.
`stallDetails`	`PersistableBundle`: A PersistableBundle that may contain additional info about the report This value cannot be `null`.

Public methods

describeContents

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

equals

public boolean equals (Object o)

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.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
`o`	`Object`: This value may be `null`.

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

getDetectionMethod

public int getDetectionMethod ()

Returns the bitmask of detection methods used to identify this suspected data stall.

Returns
`int`	The bitmask of detection methods used to identify the suspected data stall

getLinkProperties

public LinkProperties getLinkProperties ()

Returns the LinkProperties available when this report was taken.

Returns
`LinkProperties`	LinkProperties available on the Network at the reported timestamp This value cannot be `null`.

getNetwork

public Network getNetwork ()

Returns the Network for this DataStallReport.

Returns
`Network`	The Network for which this DataStallReport applied This value cannot be `null`.

getNetworkCapabilities

public NetworkCapabilities getNetworkCapabilities ()

Returns the NetworkCapabilities when this report was taken.

Returns
`NetworkCapabilities`	NetworkCapabilities available on the Network at the reported timestamp This value cannot be `null`.

getReportTimestamp

public long getReportTimestamp ()

Returns the epoch timestamp (milliseconds) for when this report was taken.

Returns
`long`	The timestamp for the report. Taken from `System#currentTimeMillis`.

getStallDetails

public PersistableBundle getStallDetails ()

Returns a PersistableBundle with additional info for this report.

Gets a bundle with details about the suspected data stall including information specific to the monitoring method that detected the data stall.

Returns
`PersistableBundle`	PersistableBundle that may contain additional information on the suspected data stall This value cannot be `null`.

hashCode

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(Object) 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(java.lang.Object) 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.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int`	a hash code value for this object.

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: This value cannot be `null`.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
