NetworkScanRequest

public final class NetworkScanRequest
extends Object implements Parcelable

java.lang.Object
   ↳ android.telephony.NetworkScanRequest


Defines a request to peform a network scan. This class defines whether the network scan will be performed only once or periodically until cancelled, when the scan is performed periodically, the time interval is not controlled by the user but defined by the modem vendor.

Summary

Constants

int SCAN_TYPE_ONE_SHOT

Performs the scan only once

NetworkScanRequest

public NetworkScanRequest (int scanType, 
                RadioAccessSpecifier[] specifiers, 
                int searchPeriodicity, 
                int maxSearchTime,

                int incrementalResultsPeriodicity, 
                ArrayList<String> mccMncs)

Creates a new NetworkScanRequest with mScanType and network mSpecifiers

Parameters
scanType int: The type of the scan, can be either one shot or periodic

specifiers RadioAccessSpecifier: the radio network with bands / channels to be scanned

searchPeriodicity int: The modem will restart the scan every searchPeriodicity seconds if no network has been found, until it reaches the maxSearchTime. Only valid when scan type is periodic scan.

maxSearchTime int: Maximum duration of the search (in seconds)

incrementalResults boolean: Indicates whether the modem should report incremental results of the network scan to the client

incrementalResultsPeriodicity int: Indicates the periodicity with which the modem should report incremental results to the client (in seconds), only valid when incrementalResults is true

mccMncs ArrayList: Describes the list of PLMN ids (MCC-MNC), once any network in the list has been found, the scan will be terminated by the modem.

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: the reference object with which to compare.

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

getIncrementalResults

public boolean getIncrementalResults ()

Returns whether incremental result is enabled. FALSE – Incremental results is not enabled. TRUE – Incremental results is reported.

Returns
boolean

getIncrementalResultsPeriodicity

public int getIncrementalResultsPeriodicity ()

Returns the periodicity in seconds of incremental results.

Returns
int

getMaxSearchTime

public int getMaxSearchTime ()

Returns maximum duration of the periodic search in seconds.

Returns
int

getPlmns

public ArrayList<String> getPlmns ()

Returns the List of PLMN ids (MCC-MNC) for early termination of scan. If any PLMN of this list is found, search should end at that point and results with all PLMN found till that point should be sent as response.

Returns
ArrayList<String>

getScanType

public int getScanType ()

Returns the type of the scan.

Returns
int Value is SCAN_TYPE_ONE_SHOT, or SCAN_TYPE_PERIODIC

getSearchPeriodicity

public int getSearchPeriodicity ()

Returns the search periodicity in seconds.

Returns
int

getSpecifiers

public RadioAccessSpecifier[] getSpecifiers ()

Returns the radio access technologies with bands or channels that need to be scanned.

Returns
RadioAccessSpecifier[]

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: 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
