Method Details

getObjectNode

public UaObjectNode getObjectNode()

Get the UaObjectNode this method belongs to.

Returns:

the UaObjectNode this method belongs to.

getMethodNode

public UaMethodNode getMethodNode()

Get the UaMethodNode for this method.

Returns:

the UaMethodNode for this method.

public org.eclipse.milo.opcua.stack.core.types.structured.Argument[] getInputArguments()

Get the input arguments for this method.

The array will be empty if there are no inputs.

Returns:

the input arguments for this method.

getOutputArguments

public org.eclipse.milo.opcua.stack.core.types.structured.Argument[] getOutputArguments()

Get the output arguments for this method.

The array will be empty if there are no outputs.

Returns:

the output arguments for this method.

call

public org.eclipse.milo.opcua.stack.core.types.builtin.Variant[] call(org.eclipse.milo.opcua.stack.core.types.builtin.Variant[] inputs)
                                                               throws UaMethodException,
org.eclipse.milo.opcua.stack.core.UaException

Call this method, passing the values in inputs for the input arguments.

Parameters:

inputs - an array of Variants containing the input values.

Returns:

an array of Variants containing the output values.

Throws:

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

UaMethodException - if the operation-level result was not good.

callAsync

public CompletableFuture<org.eclipse.milo.opcua.stack.core.types.builtin.Variant[]> callAsync(org.eclipse.milo.opcua.stack.core.types.builtin.Variant[] inputs)

Call this method, passing the values in inputs for the input arguments.

This method completes asynchronously.

Parameters:

inputs - an array of Variants containing the input values.

Returns:

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