public final class Endpoint
- Object
- Endpoint
Another device seen advertising the same service id.
An endpoint id is only meaningful for as long as the endpoint is visible
– both platforms mint a fresh one per discovery session – so persist
nothing from here. To recognise a device across sessions, use
com.codename1.nearby.companion or a name the app chooses itself.
Constructors
public Endpoint(String id, String name, String serviceId) | Ports construct these; application code receives them through TransportListener. |
Methods
public String getId() | The endpoint id, which every other call in this package takes. |
public String getName() | The name the peer advertised itself under. |
public String getServiceId() | The service id this endpoint was found under. |
public boolean equals(Object o) | Indicates whether some other object is “equal to” this one. |
public int hashCode() | Returns a hash code value for the object. |
public String toString() | Returns a string representation of the object. |

TransportListener.Parameters
idString- the platform’s endpoint id
nameString- the name the peer advertised
serviceIdString- the service both ends agreed on
Method details
getId
public String getId()The endpoint id, which every other call in this package takes.
Valid only while this endpoint is visible.
getName
public String getName()The name the peer advertised itself under. Never null.
getServiceId
public String getServiceId()The service id this endpoint was found under. Never null.
equals
public boolean equals(Object o)Indicates whether some other object is “equal to” this one.
The equals method implements an equivalence relation: It is reflexive: for any reference value x, x.equals(x) should return true. It is symmetric: for any 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 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 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 object is modified. For any non-null reference value x, x.equals(null) should return false.
The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).
hashCode
public int hashCode()Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.
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(Object) 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(java.lang.Object) 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 hashtables.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
toString
public String toString()Returns a string representation of the object. In general, the toString method returns a string that “textually represents” this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@’, and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + ‘@’ + Integer.toHexString(hashCode())
