InformationElement

Added in API level 33
public InformationElement (int id, 
                int idExt, 
                byte[] bytes)

Constructs InformationElements from beacon.

Parameters
id int: element id

idExt int: element id extension

InformationElement

Added in API level 30
public InformationElement (ScanResult.InformationElement rhs)

Parameters
rhs ScanResult.InformationElement: This value cannot be null.

Public methods

equals

Added in API level 30
public boolean equals (Object that)

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
that Object: the reference object with which to compare.

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

getBytes

Added in API level 30
public ByteBuffer getBytes ()

Get the specific content of the information element.

Returns
ByteBuffer This value cannot be null.

getId

Added in API level 30
public int getId ()

The element ID of the information element. Defined in the IEEE 802.11-2016 spec Table 9-77.

Returns
int

getIdExt

Added in API level 30
public int getIdExt ()

The element ID Extension of the information element. Defined in the IEEE 802.11-2016 spec Table 9-77.

Returns
int

hashCode

Added in API level 30
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.
