Overview
Design page for Bugzilla 208595 - Register Queries with Visualization - programming model [1]
This ER specifies the following Data Visualization Outputters, which conform to the Data Visualization programming model CosmosDataReportingComponent10_209226
Domain Outputter
The COSMOS Navigator defines the Domain Outputter as the root node of the tree in its view.jprop definition:
{
clazz: "org.eclipse.cosmos.provisional.dr.ps.components.widget.Navigator",
query: {nodeClass:'*'},
id:"myTree",
initQueryHandler: "json?service=org/eclipse/cosmos/internal/dr/drs/service/outputter/DomainOutputter&query=init",
publish: ['properties', 'detail']
}
The initial query handler specifies a query parameter value of "init" to indicate initialization of the Domain root node. The initialization of the Domain Outputter uses the EPR of the Management Domain, which is configured in the deployment descriptor file (web.xml) as follows:
<context-param> <param-name>MANAGEMENT_DOMAIN_EPR</param-name> <param-value>http://localhost:8080/domain/services/managementDomain</param-value> </context-param>
The root node JSON specifies the nodeClass, title, epr and query used to expand the node. For example:
{ identifier: "object", label: "title",
items:[ { nodeClass:"domain", title:"Domain",
expandQuery:"domain", object:"0",
epr:"http://localhost:8080/domain/services/managementDomain"}
]
}
When the user expands the node, the Domain Outputter uses the EPR of the domain with the management domain client interface to obtain the list of Brokers (getBrokers). It transforms the Broker list into JSON, which is rendered by the visualization as the child nodes of the domain. For example:
{ identifier: "object", label: "title",
items:[ { nodeClass:"broker", title:"Broker", expandQuery:"broker",
object:"Broker", epr:"http://localhost:8080/broker/services/broker" }
]
}
Note that the expansion query (expandQuery) is configured to use the Broker Outputter, which links the Broker Outputter as the child nodes of the broker node.
