Method Detail

getSourceTimestamp

org.eclipse.milo.opcua.stack.core.types.builtin.DateTime getSourceTimestamp()
                                                                     throws org.eclipse.milo.opcua.stack.core.UaException

Get the local value of the SourceTimestamp Node.

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

Returns:

the local value of the SourceTimestamp Node.

Throws:

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

setSourceTimestamp

void setSourceTimestamp(org.eclipse.milo.opcua.stack.core.types.builtin.DateTime sourceTimestamp)
                 throws org.eclipse.milo.opcua.stack.core.UaException

Set the local value of the SourceTimestamp Node.

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

Parameters:

sourceTimestamp - the local value to set for the SourceTimestamp Node.

Throws:

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

readSourceTimestamp

org.eclipse.milo.opcua.stack.core.types.builtin.DateTime readSourceTimestamp()
                                                                      throws org.eclipse.milo.opcua.stack.core.UaException

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

Returns:

the DateTime value read from the server.

Throws:

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

writeSourceTimestamp

void writeSourceTimestamp(org.eclipse.milo.opcua.stack.core.types.builtin.DateTime sourceTimestamp)
                   throws org.eclipse.milo.opcua.stack.core.UaException

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

Parameters:

sourceTimestamp - the DateTime value to write to the server.

Throws:

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

readSourceTimestampAsync

CompletableFuture<? extends org.eclipse.milo.opcua.stack.core.types.builtin.DateTime> readSourceTimestampAsync()

An asynchronous implementation of readSourceTimestamp().

Returns:

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

writeSourceTimestampAsync

CompletableFuture<org.eclipse.milo.opcua.stack.core.types.builtin.StatusCode> writeSourceTimestampAsync(org.eclipse.milo.opcua.stack.core.types.builtin.DateTime sourceTimestamp)

An asynchronous implementation of writeSourceTimestamp(DateTime).

Returns:

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

getSourceTimestampNode

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

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

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

Returns:

the SourceTimestamp 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.

getSourceTimestampNodeAsync

CompletableFuture<? extends PropertyType> getSourceTimestampNodeAsync()

Asynchronous implementation of getSourceTimestampNode().

Returns:

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