NetworkCapabilities

public final class NetworkCapabilities
extends Object implements Parcelable

java.lang.Object
↳	android.net.NetworkCapabilities

This class represents the capabilities of a network. This is used both to specify needs to ConnectivityManager and when inspecting a network. Note that this replaces the old TYPE_MOBILE method of network selection. Rather than indicate a need for Wi-Fi because an application needs high bandwidth and risk obsolescence when a new, fast network appears (like LTE), the application should specify it needs high bandwidth. Similarly if an application needs an unmetered network for a bulk transfer it can specify that rather than assuming all cellular based connections are metered and all Wi-Fi based connections are not.

CREATOR

Added in API level 21

Creator<NetworkCapabilities> CREATOR

Public constructors

NetworkCapabilities

Added in API level 21

NetworkCapabilities (NetworkCapabilities nc)

Parameters
`nc`	`NetworkCapabilities`

Public methods

describeContents

Added in API level 21

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(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.

equals

Added in API level 21

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.

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
`obj`	`Object`: the reference object with which to compare.

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

getLinkDownstreamBandwidthKbps

Added in API level 21

int getLinkDownstreamBandwidthKbps ()

Retrieves the downstream bandwidth for this network in Kbps. This always only refers to the estimated first hop transport bandwidth.

Returns
`int`	The estimated first hop downstream (network to device) bandwidth.

getLinkUpstreamBandwidthKbps

Added in API level 21

int getLinkUpstreamBandwidthKbps ()

Retrieves the upstream bandwidth for this network in Kbps. This always only refers to the estimated first hop transport bandwidth.

Returns
`int`	The estimated first hop upstream (device to network) bandwidth.

hasCapability

Added in API level 21

boolean hasCapability (int capability)

Tests for the presence of a capabilitity on this instance.

Parameters
`capability`	`int`: the `NetworkCapabilities.NET_CAPABILITY_*` to be tested for.

Returns
`boolean`	`true` if set on this instance.

hasTransport

Added in API level 21

boolean hasTransport (int transportType)

Tests for the presence of a transport on this instance.

Parameters
`transportType`	`int`: the `NetworkCapabilities.TRANSPORT_*` to be tested for.

Returns
`boolean`	`true` if set on this instance.

hashCode

Added in API level 21

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^TM programming language.)

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

toString

Added in API level 21

String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String`	a string representation of the object.

writeToParcel

Added in API level 21

void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: The Parcel in which the object should be written.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`.
