Interface NodeRegistry

All Known Implementing Classes:

TopologicallySortedDependencyGraph

public interface NodeRegistry

Holds all the currently registered nodes and factories in a graph. If a node cannot be found then a NodeFactory will be used to create a new instance, using the provided map for configuration.

Users interact with the NodeRegistry through callbacks on the NodeFactory interface.

Method Detail

findOrCreateNode

<T> T findOrCreateNode(Class<T> clazz,
                       Map<String,Object> config,
                       String variableName)

Find or create a node using a registered NodeFactory. The generated node will have private scope and the name will be generated from a NodeNameProducer strategy if the supplied name is null.

Type Parameters:

T - The type of the node to be created.

Parameters:

clazz - The class of type T

config - a map used by a NodeFactory to create a node.

variableName - the variable name in the SEP

Returns:

The node that is referenced by the config map.

findOrCreatePublicNode

<T> T findOrCreatePublicNode(Class<T> clazz,
                             Map<String,Object> config,
                             String variableName)

Find or create a node using a registered NodeFactory. The generated node will have public scope and the name will be generated from a NodeNameProducer strategy if the supplied name is null.

Type Parameters:

T - The type of the node to be created.

Parameters:

clazz - The class of type T

config - a map used by a NodeFactory to create a node.

variableName - the variable name in the SEP

Returns:

The node that is referenced by the config map.

registerNode

<T> T registerNode(T node,
                   String variableName)

Register a user created node with Fluxtion generator, no NodeFactory's will be used in this operation. The node will have private scope and the name will be generated from a NodeNameProducer strategy if the supplied name is null.

Type Parameters:

T - The type of the node to be created.

Parameters:

node - The node to add to the SEP

variableName - the variableName name of the node

Returns:

registerPublicNode

<T> T registerPublicNode(T node,
                         String variableName)

Register a user created node with Fluxtion generator, no NodeFactory's will be used in this operation. The node will have public scope and the name will be generated from a NodeNameProducer strategy if the supplied name is null.

Type Parameters:

T - The type of the node to be created.

Parameters:

node - The node to add to the SEP

variableName - the variableName name of the node

Returns:

registerAuditor

<T extends com.fluxtion.runtime.audit.Auditor> T registerAuditor(T node,
                                                                 String auditorName)

Register an Auditor with Fluxtion generator. The Auditor will have public scope registered with the name provided.

Type Parameters:

T - The Auditor class

Parameters:

node - The Auditor to register

auditorName - the public name of the Auditor

Returns:

The registered Auditor
