CREATOR

public static final Creator<TrafficDescriptor> CREATOR

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.

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.

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.

getConnectionCapability

public int getConnectionCapability ()

Get the connection capability of the traffic.

The connection capability indicates the type of traffic. The values are defined in 3GPP TS 24.526, Table 5.2.1. This is used by the network for UE Route Selection Policy (URSP) traffic matching.

When used to request a data connection, the framework may only use one specific connection capability to match a network capability, even if the underlying APN supports multiple (e.g., both internet and MMS). In such cases, only the single matched connection capability from the network request will be sent to the modem.

getDataNetworkName

public String getDataNetworkName ()

DNN stands for Data Network Name and represents an APN as defined in 3GPP TS 23.003.

getOsAppId

public byte[] getOsAppId ()

OsAppId identifies a broader traffic category. Although it names Os/App id, it only includes OS version with a general/broader category id used as app id.

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 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.

toString

public String toString ()

Returns a string representation of the object.

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.
