All Implemented Interfaces:

public class SubsystemDiscovery
extends Object
implements ResourceDiscoveryComponent<BaseComponent<?>>

Discover subsystems. We need to distinguish two cases denoted by the path plugin config:

• Path is a single 'word': here the value denotes a key in the resource path of AS7, that identifies a child type see e.g. the Connectors below the JBossWeb service in the plugin descriptor. There can be multiple resources of the given type. In addition it is possible that a path entry in configuration shares multiple types that are separated by the pipe symbol.
• Path is a key-value pair (e.g. subsystem=web ). This denotes a singleton subsystem with a fixes path within AS7 (perhaps below another resource in the tree.

discoverResources

public Set<DiscoveredResourceDetails> discoverResources(ResourceDiscoveryContext<BaseComponent<?>> context)
                                                 throws Exception

Specified by:

Throws:

Exception

shouldSkipEntryWrtIspn

protected boolean shouldSkipEntryWrtIspn(ResourceDiscoveryContext<BaseComponent<?>> context,
                             String confPath)

The as7 plugin and the JDG/Infinispan Server plugin both have a subsystem=infinispan. We need to decide which one to 'activate' depending on the type, plugin and the detected parent. Rules are:

• If the parent is a host controller or such, there is no jdg available
• If parent is eap/as7, use the type from the as7 plugin
• If parent is a jdg server, use the type from the jdg plugin.

Parameters:

context - The parent's resource component

confPath - The subsystem that got fed into discovery. Directly return is not subsystem=infinispan

Returns:

True if this subsystem should be skipped.
