GnssAntennaInfo

public final class GnssAntennaInfo
extends Object implements Parcelable

java.lang.Object
   ↳ android.location.GnssAntennaInfo


A class that contains information about a GNSS antenna. GNSS antenna characteristics can change with device configuration, such as when a device is folded open or closed. Antenna information is delivered to registered instances of Listener.

Summary

Nested classes

class GnssAntennaInfo.Builder

Builder class for GnssAntennaInfo. 

interface GnssAntennaInfo.Listener

Used for receiving GNSS antenna info from the GNSS engine. 

class GnssAntennaInfo.PhaseCenterOffset

Class containing information about the antenna phase center offset (PCO). 

class GnssAntennaInfo.SphericalCorrections

Represents corrections on a spherical mapping. 

Inherited constants

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.

getCarrierFrequencyMHz

public double getCarrierFrequencyMHz ()

Returns
double Value is 0.0f or greater

getPhaseCenterOffset

public GnssAntennaInfo.PhaseCenterOffset getPhaseCenterOffset ()

Returns a PhaseCenterOffset object encapsulating the phase center offset and corresponding uncertainties in millimeters.

Returns
GnssAntennaInfo.PhaseCenterOffset PhaseCenterOffset This value cannot be null.

getPhaseCenterVariationCorrections

public GnssAntennaInfo.SphericalCorrections getPhaseCenterVariationCorrections ()

Returns a SphericalCorrections object encapsulating the phase center variation corrections and corresponding uncertainties in millimeters.

Returns
GnssAntennaInfo.SphericalCorrections phase center variation corrections as SphericalCorrections This value may be null.

getSignalGainCorrections

public GnssAntennaInfo.SphericalCorrections getSignalGainCorrections ()

Returns a SphericalCorrections object encapsulating the signal gain corrections and corresponding uncertainties in dBi.

Returns
GnssAntennaInfo.SphericalCorrections signal gain corrections as SphericalCorrections This value may be null.

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 a string representation of the object.

writeToParcel

public void writeToParcel (Parcel parcel, 
                int flags)

Flatten this object in to a Parcel.

Parameters
parcel 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
