Interface DataTypeTreeFactory

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface DataTypeTreeFactory

A factory that creates a DataTypeTree for a given OpcUaClient.

Implementations can create different types of DataTypeTrees, such as:

• An eagerly built tree via DataTypeTreeBuilder.build(OpcUaClient)
• A lazily-loaded tree via LazyClientDataTypeTree

See Also:

• DataTypeTreeBuilder
• LazyClientDataTypeTree

Method Summary

Modifier and Type	Method	Description
org.eclipse.milo.opcua.sdk.core.typetree.DataTypeTree	create(OpcUaClient client)	Creates a DataTypeTree for the given client.
static DataTypeTreeFactory	eager()	Returns the default factory that eagerly builds a DataTypeTree using DataTypeTreeBuilder.build(OpcUaClient).
static DataTypeTreeFactory	lazy()	Returns a factory that creates a LazyClientDataTypeTree.

Method Details

create

org.eclipse.milo.opcua.sdk.core.typetree.DataTypeTree create(OpcUaClient client)
                                                      throws org.eclipse.milo.opcua.stack.core.UaException

Parameters:

client - the OpcUaClient to create a DataTypeTree for.

Returns:

a new DataTypeTree instance.

Throws:

org.eclipse.milo.opcua.stack.core.UaException - if an error occurs while creating the tree.

eager

static DataTypeTreeFactory eager()

Returns the default factory that eagerly builds a DataTypeTree using DataTypeTreeBuilder.build(OpcUaClient).

Returns:

the default DataTypeTreeFactory.

lazy

static DataTypeTreeFactory lazy()

Returns a factory that creates a LazyClientDataTypeTree.

Returns:

a DataTypeTreeFactory that creates lazy-loading trees.
