BluetoothCodecType


public final class BluetoothCodecType
extends Object implements Parcelable

java.lang.Object
   ↳ android.bluetooth.BluetoothCodecType


Represents a supported source codec type for a Bluetooth A2DP device. See BluetoothA2dp.getSupportedCodecTypes(). The codec type is uniquely identified by its name and codec identifier.

Public methods

equals

Added in API level 35
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.

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.

Parameters
o Object: This value may be null.

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

getCodecId

Added in API level 35
public long getCodecId ()

Returns the codec unique identifier. The codec identifier is 40 bits, - Bits 0-7: Audio Codec ID, as defined by [ID 6.5.1] 0x00: SBC 0x02: AAC 0xFF: Vendor - Bits 8-23: Company ID, set to 0, if octet 0 is not 0xFF. - Bits 24-39: Vendor-defined codec ID, set to 0, if octet 0 is not 0xFF.

Returns
long

getCodecName

Added in API level 35
public String getCodecName ()

Returns the codec name.

Returns
String This value cannot be null.

hashCode

Added in API level 35
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.

Returns
int a hash code value for this object.

isMandatoryCodec

Added in API level 35
public boolean isMandatoryCodec ()

Returns if the codec type is mandatory in the Bluetooth specification.

Returns
boolean

toString

Added in API level 35
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.
