GnssMeasurementRequest

PASSIVE_INTERVAL

public static final int PASSIVE_INTERVAL

Represents a passive only request. Such a request will not trigger any active GNSS measurements or power usage itself, but may receive GNSS measurements generated in response to other requests.

Note that on Android T, such a request will trigger one GNSS measurement. Another GNSS measurement will be triggered after PASSIVE_INTERVAL and so on.

Constant Value: 2147483647 (0x7fffffff)

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 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.

getIntervalMillis

public int getIntervalMillis ()

Returns the requested time interval between the reported measurements in milliseconds, or PASSIVE_INTERVAL if this is a passive, no power request. A passive request will not actively generate GNSS measurement updates, but may receive GNSS measurement updates generated as a result of other GNSS measurement requests.

If the time interval is not set, the default value is 0, which means the fastest rate the GNSS chipset can report.

The GNSS chipset may report measurements with a rate faster than requested.

Note that on Android T, a request interval of PASSIVE_INTERVAL will first trigger one GNSS measurement. Another GNSS measurement will be triggered after PASSIVE_INTERVAL milliseconds ans so on.

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. (The hashCode may or may not be implemented as some function of an object's memory address at some point in time.)

isFullTracking

public boolean isFullTracking ()

Represents whether to enable full GNSS tracking.

If true, GNSS chipset switches off duty cycling. In such a mode, no clock discontinuities are expected, and when supported, carrier phase should be continuous in good signal conditions. All non-blocklisted, healthy constellations, satellites and frequency bands that are meaningful to positioning accuracy must be tracked and reported in this mode. The GNSS chipset will consume more power in full tracking mode than in duty cycling mode. If false, GNSS chipset optimizes power via duty cycling, constellations and frequency limits, etc.

Full GNSS tracking mode affects GnssMeasurement and other GNSS functionalities including GNSS location.

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())
 

writeToParcel

public void writeToParcel (Parcel parcel, 
                int flags)

Flatten this object in to a Parcel.
