Inherited constants

From class Parcelable

Int

CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Int

PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Public methods
Int	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
Boolean	`equals(other: Any?)` Indicates whether some other object is "equal to" this one.
Long	`getCodecId()` Returns the codec unique identifier.
String	`getCodecName()` Returns the codec name.
Int	`hashCode()` Returns a hash code value for the object.
Boolean	`isMandatoryCodec()` Returns if the codec type is mandatory in the Bluetooth specification.
String	`toString()` Returns a string representation of the object.
Unit	`writeToParcel(dest: Parcel, flags: Int)` Flatten this object in to a Parcel.

Public methods

describeContents

Added in API level 35

fun describeContents(): Int

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.

Return
`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

Added in API level 35

fun equals(other: Any?): Boolean

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
`obj`	the reference object with which to compare.
`o`	This value may be `null`.

Return
`Boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

getCodecId

Added in API level 35

fun getCodecId(): Long

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.

getCodecName

Added in API level 35

fun getCodecName(): String

Returns the codec name.

Return
`String`	This value cannot be `null`.

hashCode

Added in API level 35

fun hashCode(): Int

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.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.

Return
`Int`	a hash code value for this object.

isMandatoryCodec

Added in API level 35

fun isMandatoryCodec(): Boolean

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

toString

Added in API level 35

fun toString(): String

Returns a string representation of the object.

Return
`String`	a string representation of the object.

writeToParcel

Added in API level 35

fun writeToParcel(
    dest: Parcel, 
    flags: Int
): Unit

Flatten this object in to a Parcel.

Parameters
`dest`	Parcel: This value cannot be `null`.
`flags`	Int: Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: `PARCELABLE_WRITE_RETURN_VALUE`

Properties

CREATOR

Added in API level 35

static val CREATOR: Parcelable.Creator<BluetoothCodecType!>
