Method Detail

isExecutable

public Boolean isExecutable()

The returned attribute is the most recently seen value; it is not read live from the server.

Specified by:

isExecutable in interface MethodNode

See Also:

readExecutable()

isUserExecutable

public Boolean isUserExecutable()

The returned attribute is the most recently seen value; it is not read live from the server.

Specified by:

isUserExecutable in interface MethodNode

See Also:

readUserExecutable()

setExecutable

public void setExecutable(Boolean executable)

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

Specified by:

setExecutable in interface MethodNode

See Also:

writeExecutable(Boolean)

setUserExecutable

public void setUserExecutable(Boolean userExecutable)

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

Specified by:

setUserExecutable in interface MethodNode

See Also:

writeUserExecutable(Boolean)

readExecutable

public Boolean readExecutable()
                       throws org.eclipse.milo.opcua.stack.core.UaException

Read the Executable attribute for this Node from the server and update the local attribute if the operation succeeds.

Returns:

the Boolean read from the server.

Throws:

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

readUserExecutable

public Boolean readUserExecutable()
                           throws org.eclipse.milo.opcua.stack.core.UaException

Read the UserExecutable attribute for this Node from the server and update the local attribute if the operation succeeds.

Returns:

the Boolean read from the server.

Throws:

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

writeExecutable

public void writeExecutable(Boolean executable)
                     throws org.eclipse.milo.opcua.stack.core.UaException

Write a new Executable attribute for this Node to the server and update the local attribute if the operation succeeds.

Parameters:

executable - the Boolean to write to the server.

Throws:

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

writeUserExecutable

public void writeUserExecutable(Boolean userExecutable)
                         throws org.eclipse.milo.opcua.stack.core.UaException

Write a new UserExecutable attribute for this Node to the server and update the local attribute if the operation succeeds.

Parameters:

userExecutable - the Boolean to write to the server.

Throws:

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

readNodeVersionAsync

public CompletableFuture<? extends String> readNodeVersionAsync()

Get the value of the MethodNodeProperties.NodeVersion Property, if it exists.

The NodeVersion Property is used to indicate the version of a Node.

The NodeVersion Property is updated each time a Reference is added or deleted to the Node the Property belongs to. Attribute value changes do not cause the NodeVersion to change. Clients may read the NodeVersion Property or subscribe to it to determine when the structure of a Node has changed.

This Property is optional. If not present, the future will be completed exceptionally with a UaException indicating StatusCodes.Bad_NotFound.

Returns:

the value of the NodeVersion Property, if it exists.

MethodNodeProperties

readInputArgumentsAsync

public CompletableFuture<org.eclipse.milo.opcua.stack.core.types.structured.Argument[]> readInputArgumentsAsync()

Get the value of the MethodNodeProperties.InputArguments Property, if it exists.

The InputArguments Property is used to specify the arguments that shall be used by a client when calling the Method.

This Property is optional. If not present, the future will be completed exceptionally with a UaException indicating StatusCodes.Bad_NotFound.

Returns:

the value of the InputArguments Property, if it exists.

See Also:

MethodNodeProperties

readOutputArgumentsAsync

public CompletableFuture<org.eclipse.milo.opcua.stack.core.types.structured.Argument[]> readOutputArgumentsAsync()

Get the value of the MethodNodeProperties.OutputArguments Property, if it exists.

The OutputArguments Property specifies the result returned from the Method call.

This Property is optional. If not present, the future will be completed exceptionally with a UaException indicating StatusCodes.Bad_NotFound.

Returns:

the value of the OutputArguments Property, if it exists.

See Also:

MethodNodeProperties

writeNodeVersionAsync

public CompletableFuture<org.eclipse.milo.opcua.stack.core.types.builtin.StatusCode> writeNodeVersionAsync(String nodeVersion)

Set the value of the MethodNodeProperties.NodeVersion Property, if it exists.

Parameters:

nodeVersion - the value to set.

Returns:

a CompletableFuture that completes with the StatusCode of the write operation.

See Also:

MethodNodeProperties

public CompletableFuture<org.eclipse.milo.opcua.stack.core.types.builtin.StatusCode> writeInputArgumentsAsync(org.eclipse.milo.opcua.stack.core.types.structured.Argument[] inputArguments)

Set the value of the MethodNodeProperties.InputArguments Property, if it exists.

Parameters:

inputArguments - the value to set.

Returns:

a CompletableFuture that completes with the StatusCode of the write operation.
