Method Detail

getChanges

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

Get the local value of the Changes Node.

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

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

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

Set the local value of the Changes Node.

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

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

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

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

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

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

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

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

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

An asynchronous implementation of readChanges().

Returns:

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

writeChangesAsync

CompletableFuture<org.eclipse.milo.opcua.stack.core.types.builtin.StatusCode> writeChangesAsync(org.eclipse.milo.opcua.stack.core.types.structured.SemanticChangeStructureDataType[] changes)

An asynchronous implementation of writeChanges(SemanticChangeStructureDataType[]).

Returns:

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

getChangesNode

PropertyType getChangesNode()
                     throws org.eclipse.milo.opcua.stack.core.UaException

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

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

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.

getChangesNodeAsync

CompletableFuture<? extends PropertyType> getChangesNodeAsync()

Asynchronous implementation of getChangesNode().

Returns:

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