CREATOR

Added in API level 33
public static final Creator<TransportDiscoveryData> CREATOR

Public constructors

TransportDiscoveryData

Added in API level 33
public TransportDiscoveryData (byte[] transportDiscoveryData)

Creates a TransportDiscoveryData instance from byte arrays.

Uses the transport discovery data bytes and parses them into an usable class.

Parameters
transportDiscoveryData byte: the raw discovery data.
This value cannot be null.

TransportDiscoveryData

Added in API level 33
public TransportDiscoveryData (int transportDataType, 
                List<TransportBlock> transportBlocks)

Creates a TransportDiscoveryData instance.

Parameters
transportDataType int: the Transport Discovery Data AD Type

transportBlocks List: the list of Transport Blocks.
This value cannot be null.

Public methods

describeContents

Added in API level 33
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

equals

Added in API level 33
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.

Parameters
obj Object: This value may be null.

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

getTransportBlocks

Added in API level 33
public List<TransportBlock> getTransportBlocks ()

Returns
List<TransportBlock> the list of TransportBlock in this TransportDiscoveryData or an empty list if there are no Transport Blocks.
This value cannot be null.

getTransportDataType

Added in API level 33
public int getTransportDataType ()

Gets the transport data type.

Returns
int

hashCode

Added in API level 33
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.

toByteArray

Added in API level 33
public byte[] toByteArray ()

Converts this TransportDiscoveryData to byte array

Returns
byte[] byte array representation of this Transport Discovery Data or null if the conversion failed

toString

Added in API level 33
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.

totalBytes

Added in API level 33
public int totalBytes ()

Returns
int total byte count of this TransportDataDiscovery

writeToParcel

Added in API level 33
public void writeToParcel (Parcel dest, 
                int flags)

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.PARCELABLE_WRITE_RETURN_VALUE.
Value is either 0 or a combination of the following:
