This project is intended to hold reusable models and messages used throughout the csw source code.
This project is intended to hold reusable models and messages used throughout the csw source code.
This also provides out of the box support to cater to the diverse communication requirements. Consumer of this library will be able to create Commands, Events, States to store ParameterSets.
This packages contains classes, traits and models used to create *commands* and *events*. These are all based on type-safe keys and items (a set of values with optional units). Each key has a specific type and the key's values must be of that type.
Two types of csw.messages.commands.Command are supported:
Following are the concrete commands supported by csw:
Two types of csw.messages.events.Event are supported:
Another important feature provided by *commands* package is csw.messages.commands.matchers.Matcher One of the use case for using matcher is when Assembly sends csw.messages.scaladsl.CommandMessage.Oneway command to HCD and in response to this command HCD keeps publishing its current state. Then Assembly can use Matcher with the matching definition as provided by csw.messages.commands.matchers.StateMatcher to match against the current states published by HCD.
These packages contain reusable classes, traits and models. We are keeping all the models which are getting transferred over the wire and
requires serialization and deserialization in csw-messages
project. All the models are marked with csw.messages.TMTSerializable.
csw.messages.TMTSerializable is a marker trait which extends Serializable. This is configured to use kryo
serialization.
Also these models are being shared between multiple projects. csw-location
, csw-framework
and csw-logging
depends on csw-messages
project
which uses these models.
Location Service uses csw.messages.location.Connection model to register component/container of type:
When you resolve/find a csw.messages.location.Connection, you get csw.messages.location.Location in return which can be one of below type:
Framework package contains following actor messages:
This package supports serialization and deserialization of commands, events and state variables in following formats:
All the param and event classes are immutable. The set
methods return a new instance of the object with a
new item added and the get
methods return an Option, in case the Key is not found. There are also value
methods
that return a value directly, throwing an exception if the key or value is not found.
A set of standard key types and matching items are defined. Each key accepts one or more values of the given type.
Following csw.messages.params.generics.KeyType are supported by csw:
