CREATOR

public static final Creator<ScanFilter> CREATOR

A Parcelable.Creator to create ScanFilter from parcel.

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.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

getAdvertisingData

public byte[] getAdvertisingData ()

Returns the advertising data of this filter.

getAdvertisingDataMask

public byte[] getAdvertisingDataMask ()

Returns the advertising data mask of this filter.

getAdvertisingDataType

public int getAdvertisingDataType ()

Returns the advertising data type of this filter. Returns ScanRecord.DATA_TYPE_NONE if the type is not set. The values of advertising data type are defined in the Bluetooth Generic Access Profile (https://www.bluetooth.com/specifications/assigned-numbers/)

getDeviceAddress

public String getDeviceAddress ()

getDeviceName

public String getDeviceName ()

Returns the filter set the device name field of Bluetooth advertisement data.

getManufacturerData

public byte[] getManufacturerData ()

getManufacturerDataMask

public byte[] getManufacturerDataMask ()

getManufacturerId

public int getManufacturerId ()

Returns the manufacturer id. -1 if the manufacturer filter is not set.

getServiceData

public byte[] getServiceData ()

getServiceDataMask

public byte[] getServiceDataMask ()

getServiceDataUuid

public ParcelUuid getServiceDataUuid ()

getServiceSolicitationUuid

public ParcelUuid getServiceSolicitationUuid ()

Returns the filter set on the service Solicitation uuid.

getServiceSolicitationUuidMask

public ParcelUuid getServiceSolicitationUuidMask ()

Returns the filter set on the service Solicitation uuid mask.

getServiceUuid

public ParcelUuid getServiceUuid ()

Returns the filter set on the service uuid.

getServiceUuidMask

public ParcelUuid getServiceUuidMask ()

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 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 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.

matches

public boolean matches (ScanResult scanResult)

Check if the scan filter matches a scanResult. A scan result is considered as a match if it matches all the field filters.

toString

public String toString ()

Returns a string representation of the object.

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.
