Properties

DataTypeId

Gets the node identifier of the DataType of the value represented.

C# 

public override sealed OpcNodeId DataTypeId { get; }


Property Value

OpcNodeId

An instance of the OpcNodeId representing the node identifier of the DataType.

Value

Gets or sets the T value represented.

C# 

public T Value { get; set; }


Property Value

T

The value of the type T associated with the metadata represented.

ValueAsObject

Gets or sets the value represented.

C# 

public object ValueAsObject { get; set; }


Property Value

Object

The value associated with the metadata represented.

Methods

CompareTo(Object)

Compares the current OpcValue´1 with the other.

C# 

public override int CompareTo(object other)


Parameters

other Object

The OpcValue´1 to compare with this OpcValue´1.


Returns

Int32

A 32-bit signed integer that indicates the relative order of the objects being compared (CompareTo(Object)).

CompareTo(OpcValue)

Compares the current OpcValue´1 with another OpcValue´1.

C# 

public override int CompareTo(OpcValue other)


Parameters

other OpcValue

The OpcValue´1 to compare with this OpcValue´1.


Returns

Int32

A 32-bit signed integer that indicates the relative order of the objects being compared (CompareTo(0)).

CompareTo(OpcValue<T>)

Compares the current OpcValue´1 with another OpcValue´1.

C# 

public virtual int CompareTo(OpcValue<T> other)


Parameters

other OpcValue`1

The OpcValue´1 to compare with this OpcValue´1.


Returns

Int32

A 32-bit signed integer that indicates the relative order of the objects being compared (CompareTo(0)).

Equals(Object)

C# 

public override bool Equals(object other)


Parameters

other Object

Returns

Boolean

The value true if the specified OpcValue´1 is equal to the current OpcValue; otherwise the value false.

Equals(OpcValue)

Determines whether the specified other is equal to this OpcValue´1.

C# 

public override bool Equals(OpcValue other)


Parameters

other OpcValue

The OpcValue´1 to compare to the current OpcValue´1.


Returns

Boolean

The value true if the specified OpcValue´1 is equal to the current OpcValue; otherwise the value false.

Equals(OpcValue<T>)
