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 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: This value may be null.

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

getApnSetting

public ApnSetting getApnSetting ()

Return the APN Settings for this data connection.

Returns
ApnSetting the ApnSetting that was used to configure this data connection. This value may be null.

getLastCauseCode

public int getLastCauseCode ()

Returns the cause code generated by the most recent state change. Return the cause code for the most recent change in getState(). In the event of an error, this cause code will be non-zero.

Returns
int Value is DataFailCause.NONE, DataFailCause.OPERATOR_BARRED, DataFailCause.NAS_SIGNALLING, DataFailCause.LLC_SNDCP, DataFailCause.INSUFFICIENT_RESOURCES, DataFailCause.MISSING_UNKNOWN_APN,

getLinkProperties

public LinkProperties getLinkProperties ()

Get the properties of the network link LinkProperties.

Returns
LinkProperties This value may be null.

getNetworkType

public int getNetworkType ()

Returns the network type associated with this data connection. Return the current/latest (radio) bearer technology that carries this data connection. For a variety of reasons, the network type can change during the life of the data connection, and this information is not reliable unless the physical link is currently active; (there is currently no mechanism to know whether the physical link is active at any given moment). Thus, this value is generally correct but may not be relied-upon to represent the status of the radio bearer at any given moment.

Returns
int Value is TelephonyManager.NETWORK_TYPE_UNKNOWN, TelephonyManager.NETWORK_TYPE_GPRS, TelephonyManager.NETWORK_TYPE_EDGE, TelephonyManager.NETWORK_TYPE_UMTS, TelephonyManager.NETWORK_TYPE_CDMA, TelephonyManager.NETWORK_TYPE_EVDO_0, TelephonyManager.NETWORK_TYPE_EVDO_A, TelephonyManager.NETWORK_TYPE_1xRTT, TelephonyManager.NETWORK_TYPE_HSDPA, TelephonyManager.NETWORK_TYPE_HSUPA, TelephonyManager.NETWORK_TYPE_HSPA, TelephonyManager.NETWORK_TYPE_IDEN, TelephonyManager.NETWORK_TYPE_EVDO_B, TelephonyManager.NETWORK_TYPE_LTE, TelephonyManager.NETWORK_TYPE_EHRPD, TelephonyManager.NETWORK_TYPE_HSPAP, TelephonyManager.NETWORK_TYPE_GSM, TelephonyManager.NETWORK_TYPE_TD_SCDMA, TelephonyManager.NETWORK_TYPE_IWLAN, or TelephonyManager.NETWORK_TYPE_NR

getState

public int getState ()

Returns the high-level state of this data connection.

Returns
int Value is TelephonyManager.DATA_UNKNOWN, TelephonyManager.DATA_DISCONNECTED, TelephonyManager.DATA_CONNECTING, TelephonyManager.DATA_CONNECTED, or TelephonyManager.DATA_SUSPENDED

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.

toString

public 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 This value cannot be null.

writeToParcel

public void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
out 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
