Source (The Tree Manager Framework 3.0.1-4.1.0-125723 API)

All Superinterfaces:

Serializable

All Known Implementing Classes:

AbstractSource
```
public interface Source
extends Serializable
```
A model of a data source managed by the plugin.
This model provides information that the service uses to dispatch client requests to the plugin (SourceReader, SourceWriter), as well as to manage its lifetime (SourceLifecycle).
It also provides information about the source that the service publishes in the infrastructure on behalf of the plugin (identifier, data type, description, date of creation and last modification, cardinality, etc).
This information must be configured by the plugin prior to source initialisation and, when appropriate, managed over the source;s lifetime (e.g. updates to cardinality and last modification dates).
This model also accepts information from the service that the plugin uses to access the local environment (Environment) and to communicate back to the service events of the relevance about the source (SourceNotifier).
This information is set by the service prior to source initialisation (cf. SourceLifecycle.init() and the plugin should not use it until then.

```
String id()
```
    Returns the identifier of the source.
    
    Returns:
    the identifier
  - types
```
List<QName> types()
```
    Returns the tree types of the source.
    
    Returns:
    the types
  - name
```
String name()
```
    Returns the name of the source.
    
    Returns:
    the name
  - description
```
String description()
```
    Returns the free-form description of the source.
    
    Returns:
    the description
  - properties
```
List<Property> properties()
```
    Returns the properties of the source.
    
    Returns:
    the properties
  - creationTime
```
Calendar creationTime()
```
    Returns the creation time of the source.
    
    Returns:
    the creation time
  - isUser
```
boolean isUser()
```
    Returns true if the source is a user-level source, false if it is instead system-level source.
    
    Returns:
    true if the source is a user-level source, false otherwise
  - cardinality
```
Long cardinality()
```
    Returns the cardinality of the source.
    
    Returns:
    the cardinality
  - lastUpdate
```
Calendar lastUpdate()
```
    Returns the time in which the source was last modified.
    
    Returns:
    the last modification time
  - lifecycle
```
SourceLifecycle lifecycle()
```
    Returns the SourceLifecycle.
    
    Returns:
    the lifecycle
  - reader
```
SourceReader reader()
```
    Returns the SourceReader.
    
    Returns:
    the reader, or null if the source is write-only
  - writer
```
SourceWriter writer()
```
    Returns the SourceWriter.
    
    Returns:
    the writer, or null if the source is read-only
  - setNotifier
```
void setNotifier(SourceNotifier notifier)
```
    Returns the SourceNotifier.
    This is invoked by the service prior to source initialisation. The service subscribes to the provider so as to receive notification of events fired from the plugin.
    
    Parameters:
    notifier - the notifier
  - notifier
```
SourceNotifier notifier()
```
    Returns the SourceNotifier.
    
    Returns:
    the notifier
  - environment
```
Environment environment()
```
    Returns the local Environment of the plugin.
    
    Returns:
    the environment
  - setEnvironment
```
void setEnvironment(Environment env)
```
    Sets the local Environment of the plugin.
    It is invoked by the service prior to source initialisation.
    
    Parameters:
    env - the environment
