public final class CallHandle
- Object
- CallHandle
Who is on the other end: an address plus what kind of address it is.
The system uses both parts. A CallHandleType.PHONE_NUMBER is matched
against the address book and may be reformatted for display, so it is
worth passing E.164; a CallHandleType.GENERIC handle is shown
verbatim. Passing a username as a phone number produces a call log entry
the user cannot call back.
Constructors
public CallHandle(CallHandleType type, String value) | Creates a handle. |
Methods
public static CallHandle phone(String number) | Convenience for a telephone number. |
public static CallHandle email(String address) | Convenience for an email address. |
public static CallHandle generic(String value) | Convenience for a username, room name or other opaque address. |
public CallHandleType getType() | What kind of address getValue() is. |
public String getValue() | The address itself. |
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. |

getValue() is. Never null.getValue

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())
