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`: the reference object with which to compare.

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

getAdvertisingSid

public int getAdvertisingSid ()

Returns the advertising set id. May return ScanResult#SID_NOT_PRESENT if no set id was is present.

Returns
`int`

getDataStatus

public int getDataStatus ()

Returns the data status. Can be one of ScanResult#DATA_COMPLETE or ScanResult#DATA_TRUNCATED.

Returns
`int`

getDevice

public BluetoothDevice getDevice ()

Returns the remote Bluetooth device identified by the Bluetooth device address.

Returns
`BluetoothDevice`

getPeriodicAdvertisingInterval

public int getPeriodicAdvertisingInterval ()

Returns the periodic advertising interval in units of 1.25ms. Valid range is 6 (7.5ms) to 65536 (81918.75ms). A value of ScanResult#PERIODIC_INTERVAL_NOT_PRESENT means periodic advertising interval is not present.

Returns
`int`

getPrimaryPhy

public int getPrimaryPhy ()

Returns the primary Physical Layer on which this advertisment was received. Can be one of BluetoothDevice#PHY_LE_1M or BluetoothDevice#PHY_LE_CODED.

Returns
`int`

getRssi

public int getRssi ()

Returns the received signal strength in dBm. The valid range is [-127, 126].

Returns
`int`

getScanRecord

public ScanRecord getScanRecord ()

Returns the scan record, which is a combination of advertisement and scan response.

Returns
`ScanRecord`	This value may be `null`.

getSecondaryPhy

public int getSecondaryPhy ()

Returns the secondary Physical Layer on which this advertisment was received. Can be one of BluetoothDevice#PHY_LE_1M, BluetoothDevice#PHY_LE_2M, BluetoothDevice#PHY_LE_CODED or ScanResult#PHY_UNUSED - if the advertisement was not received on a secondary physical channel.

Returns
`int`

getTimestampNanos

public long getTimestampNanos ()

Returns timestamp since boot when the scan record was observed.

Returns
`long`

getTxPower

public int getTxPower ()

Returns the transmit power in dBm. Valid range is [-127, 126]. A value of ScanResult#TX_POWER_NOT_PRESENT indicates that the TX power is not present.

Returns
`int`

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.

isConnectable

public boolean isConnectable ()

Returns true if this object represents connectable scan result.

Returns
`boolean`

isLegacy

public boolean isLegacy ()

Returns true if this object represents legacy scan result. Legacy scan results do not contain advanced advertising information as specified in the Bluetooth Core Specification v5.

Returns
`boolean`

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 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
