NodeAddress class

Add something here.

class NodeAddress {
 static const _HOST = "host";
 static const _PORT = "port";
 static NodeAddress _localhost;

 final String host;
 final int port;
 
 NodeAddress(this.host, [this.port=12345]);

 factory NodeAddress.fromJsonMap(Map jsonMap) {
   return new NodeAddress(jsonMap[_HOST], jsonMap[_PORT]);
 }
 
 String toString() => "$host:$port";
 
 Map<String,dynamic> toJson() {
   var map = new Map();
   
   map[_HOST] = host;
   map[_PORT] = port;
   
   return map;
 }
 
 /// identical and '==' overload
 int get hashCode => host.hashCode + port;
 bool operator ==(other) {
   if (identical(this, other)) {
     return true;
   }
   return (other is NodeAddress && host == other.host && port == other.port);
 }
}

Constructors

new NodeAddress(String host, [int port = 12345]) #

Creates a new Object instance.

Object instances have no meaningful state, and are only useful through their identity. An Object instance is equal to itself only.

docs inherited from Object

NodeAddress(this.host, [this.port=12345]);

factory NodeAddress.fromJsonMap(Map jsonMap) #

factory NodeAddress.fromJsonMap(Map jsonMap) {
 return new NodeAddress(jsonMap[_HOST], jsonMap[_PORT]);
}

Properties

final int hashCode #

identical and '==' overload

int get hashCode => host.hashCode + port;

Operators

bool operator ==(other) #

The equality operator.

The default behavior for all Objects is to return true if and only if this and other are the same object.

Override this method to specify a different equality relation on a class. The overriding method must still be an equivalence relation. That is, it must be:

Total: It must return a boolean for all arguments. It should never throw or return null.
Reflexive: For all objects o, o == o must be true.
Symmetric: For all objects o1 and o2, o1 == o2 and o2 == o1 must either both be true, or both be false.
Transitive: For all objects o1, o2, and o3, if o1 == o2 and o2 == o3 are true, then o1 == o3 must be true.

The method should also be consistent over time, so equality of two objects should not change over time, or at least only change if one of the objects was modified.

If a subclass overrides the equality operator it should override the hashCode method as well to maintain consistency.
