public static final int CONNECTION_NONE
Cell is not a serving cell.
The cell has been measured but is neither a camped nor serving cell (3GPP 36.304).
Constant Value: 0 (0x00000000)
public static final int CONNECTION_PRIMARY_SERVING
UE is connected to cell for signalling and possibly data (3GPP 36.331, 25.331).
Constant Value: 1 (0x00000001)
public static final int CONNECTION_SECONDARY_SERVING
UE is connected to cell for data (3GPP 36.331, 25.331).
Constant Value: 2 (0x00000002)
public static final int CONNECTION_UNKNOWN
Connection status is unknown.
Constant Value: 2147483647 (0x7fffffff)
public static final int UNAVAILABLE
This value indicates that the integer field is unreported.
Constant Value: 2147483647 (0x7fffffff)
public static final long UNAVAILABLE_LONG
This value indicates that the long field is unreported.
Constant Value: 9223372036854775807 (0x7fffffffffffffff)
public int describeContents ()
Implement the Parcelable interface
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 |
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:
x
, x.equals(x)
should return
true
.
x
and y
, x.equals(y)
should return true
if and only if
y.equals(x)
returns true
.
x
, y
, and z
, if
x.equals(y)
returns true
and
y.equals(z)
returns true
, then
x.equals(z)
should return true
.
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.
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 : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
public int getCellConnectionStatus ()
Gets the connection status of this cell.
Returns | |
---|---|
int |
The connection status of the cell.
Value is CONNECTION_NONE , CONNECTION_PRIMARY_SERVING , CONNECTION_SECONDARY_SERVING , or CONNECTION_UNKNOWN |
public abstract CellIdentity getCellIdentity ()
Returns | |
---|---|
CellIdentity |
a CellIdentity instance.
This value cannot be null . |
public abstract CellSignalStrength getCellSignalStrength ()
Returns | |
---|---|
CellSignalStrength |
a CellSignalStrength instance.
This value cannot be null . |
public long getTimeStamp ()
This method is deprecated.
Use getTimestampMillis()
instead.
Approximate time this cell information was received from the modem.
Returns | |
---|---|
long |
a time stamp in nanos since boot. |
public long getTimestampMillis ()
Approximate time this cell information was received from the modem.
Value is a non-negative timestamp in the
SystemClock#elapsedRealtime()
time base.
Returns | |
---|---|
long |
a time stamp in millis since boot.
Value is a non-negative timestamp in the
SystemClock#elapsedRealtime() time base. |
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:
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.
equals(Object)
method, then calling the hashCode
method on each of
the two objects must produce the same integer result.
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. |
public boolean isRegistered ()
True if the phone is registered to a mobile network that provides service on this cell and this cell is being used or would be used for network signaling.
Returns | |
---|---|
boolean |
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 |
a string representation of the object. |
public abstract void writeToParcel (Parcel dest, int flags)
Implement the Parcelable interface
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.PARCELABLE_WRITE_RETURN_VALUE .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
