Method Detail

getChanges

public org.eclipse.milo.opcua.stack.core.types.structured.SemanticChangeStructureDataType[] getChanges()
                                                                                                throws org.eclipse.milo.opcua.stack.core.UaException

Description copied from interface: SemanticChangeEventType

Get the local value of the Changes Node.

The returned value is the last seen; it is not read live from the server.

Specified by:

getChanges in interface SemanticChangeEventType

Returns:

the local value of the Changes Node.

Throws:

org.eclipse.milo.opcua.stack.core.UaException - if an error occurs creating or getting the Changes Node.

setChanges

public void setChanges(org.eclipse.milo.opcua.stack.core.types.structured.SemanticChangeStructureDataType[] changes)
                throws org.eclipse.milo.opcua.stack.core.UaException

Description copied from interface: SemanticChangeEventType

Set the local value of the Changes Node.

The value is only updated locally; it is not written to the server.

Specified by:

setChanges in interface SemanticChangeEventType

Parameters:

changes - the local value to set for the Changes Node.

Throws:

org.eclipse.milo.opcua.stack.core.UaException - if an error occurs creating or getting the Changes Node.

readChanges

public org.eclipse.milo.opcua.stack.core.types.structured.SemanticChangeStructureDataType[] readChanges()
                                                                                                 throws org.eclipse.milo.opcua.stack.core.UaException

Description copied from interface: SemanticChangeEventType

Read the value of the Changes Node from the server and update the local value if the operation succeeds.

Specified by:

readChanges in interface SemanticChangeEventType

Returns:

the SemanticChangeStructureDataType[] value read from the server.

Throws:

org.eclipse.milo.opcua.stack.core.UaException - if a service- or operation-level error occurs.

writeChanges

public void writeChanges(org.eclipse.milo.opcua.stack.core.types.structured.SemanticChangeStructureDataType[] changes)
                  throws org.eclipse.milo.opcua.stack.core.UaException

Description copied from interface: SemanticChangeEventType

Write a new value for the Changes Node to the server and update the local value if the operation succeeds.

Specified by:

writeChanges in interface SemanticChangeEventType

Parameters:

changes - the SemanticChangeStructureDataType[] value to write to the server.

Throws:

org.eclipse.milo.opcua.stack.core.UaException - if a service- or operation-level error occurs.

readChangesAsync

public CompletableFuture<? extends org.eclipse.milo.opcua.stack.core.types.structured.SemanticChangeStructureDataType[]> readChangesAsync()

Description copied from interface: SemanticChangeEventType

An asynchronous implementation of SemanticChangeEventType.readChanges().

Specified by:

Description copied from interface: SemanticChangeEventType

An asynchronous implementation of SemanticChangeEventType.writeChanges(SemanticChangeStructureDataType[]).

Specified by:

writeChangesAsync in interface SemanticChangeEventType

Returns:

a CompletableFuture that completes successfully with the operation result or completes exceptionally if a service-level error occurs.

Description copied from interface: SemanticChangeEventType

Get the Changes PropertyType Node, or null if it does not exist.

The Node is created when first accessed and cached for subsequent calls.

Specified by:

getChangesNode in interface SemanticChangeEventType

Returns:

the Changes PropertyType Node, or null if it does not exist.

Throws:

org.eclipse.milo.opcua.stack.core.UaException - if an error occurs creating or getting the Node.

Specified by:

getChangesNodeAsync in interface SemanticChangeEventType

Returns:

a CompletableFuture that completes successfully with the ? extends PropertyType Node or completes exceptionally if an error occurs creating or getting the Node.
