Class ServiceDiscovery

java.lang.Object

io.vertx.rxjava.servicediscovery.ServiceDiscovery

public class ServiceDiscovery
extends Object

Service Discovery main entry point.

The service discovery is an infrastructure that let you publish and find `services`. A `service` is a discoverable functionality. It can be qualified by its type, metadata, and location. So a `service` can be a database, a service proxy, a HTTP endpoint. It does not have to be a vert.x entity, but can be anything. Each service is described by a Record.

The service discovery implements the interactions defined in the service-oriented computing. And to some extend, also provides the dynamic service-oriented computing interaction. So, application can react to arrival and departure of services.

A service provider can:

* publish a service record * un-publish a published record * update the status of a published service (down, out of service...)

A service consumer can:

* lookup for services * bind to a selected service (it gets a ServiceReference) and use it * release the service once the consumer is done with it * listen for arrival, departure and modification of services.

Consumer would 1) lookup for service record matching their need, 2) retrieve the ServiceReference that give access to the service, 3) get a service object to access the service, 4) release the service object once done.

A state above, the central piece of information shared by the providers and consumers are Record.

Providers and consumers must create their own ServiceDiscovery instance. These instances are collaborating in background (distributed structure) to keep the set of services in sync.

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

getRecord

public void getRecord(JsonObject filter,
                      Handler<AsyncResult<Record>> resultHandler)

Lookups for a single record.

Filters are expressed using a Json object. Each entry of the given filter will be checked against the record. All entry must match exactly the record. The entry can use the special "*" value to denotes a requirement on the key, but not on the value.

Let's take some example:

   { "name" = "a" } => matches records with name set fo "a"
   { "color" = "*" } => matches records with "color" set
   { "color" = "red" } => only matches records with "color" set to "red"
   { "color" = "red", "name" = "a"} => only matches records with name set to "a", and color set to "red"
 

If the filter is not set (null or empty), it accepts all records.

This method returns the first matching record.

Parameters:

filter - the filter.

resultHandler - handler called when the lookup has been completed. When there are no matching record, the operation succeeds, but the async result has no result (null).

getRecord

public void getRecord(JsonObject filter)

Lookups for a single record.

Let's take some example:

   { "name" = "a" } => matches records with name set fo "a"
   { "color" = "*" } => matches records with "color" set
   { "color" = "red" } => only matches records with "color" set to "red"
   { "color" = "red", "name" = "a"} => only matches records with name set to "a", and color set to "red"
 

If the filter is not set (null or empty), it accepts all records.

This method returns the first matching record.

Parameters:

filter - the filter.

rxGetRecord

public Single<Record> rxGetRecord(JsonObject filter)
