PIPointClass Class

The PIPointClass object represents a point class on a PIServer.

Inheritance Hierarchy

SystemObject
OSIsoft.AF.PIPIPointClass

Namespace: OSIsoft.AF.PI
Assembly: OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182

Syntax

public sealed class PIPointClass : IComparable, 
	IComparable<PIPointClass>, IEquatable<PIPointClass>

Public NotInheritable Class PIPointClass
	Implements IComparable, IComparable(Of PIPointClass), 
	IEquatable(Of PIPointClass)

Dim instance As PIPointClass

public ref class PIPointClass sealed : IComparable, 
	IComparable<PIPointClass^>, IEquatable<PIPointClass^>

[<SealedAttribute>]
type PIPointClass =  
    class
        interface IComparable
        interface IComparable<PIPointClass>
        interface IEquatable<PIPointClass>
    end

The PIPointClass type exposes the following members.

Properties

	Name	Description
	Name	This property identifies the name of the PIPointClass.
	Server	The PIServer for this PIPoint.

Methods

	Name	Description
	CompareTo(Object)	Compares this instance with a specified Object.
	CompareTo(PIPointClass)	Compares this instance with a specified PIPointClass.
	Equals(Object)	Determines whether the specified Object is equal to the current object. (Overrides ObjectEquals(Object).)
	Equals(PIPointClass)	Indicates whether the current object is equal to another object of the same type.
	GetAttributes	Get the list of PIPoint attribute values for this PIPointClass.
	GetAttributeValue	Get the PIPoint attribute value for the specified attribute name.
	GetHashCode	Gets the hash code for this instance of the object which is suitable for use in hashing algorithms and data structures like a hash table. (Overrides ObjectGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	ToString	Returns a String that represents the current object. (Overrides ObjectToString.)

Operators

	Name	Description
	Equality	The equality operator (==) compares its operands to determine if they are equal.
	GreaterThan	The greater than relation operator (>) compares its operands to determine which one is greater than the other.
	GreaterThanOrEqual	The greater than or equal relation operator (>=) compares its operands to determine which one is greater than or equal to the other.
	Inequality	The inequality operator (!=) compares its operands to determine if they are not equal.
	LessThan	The less than relation operator (<) compares its operands to determine which one is less than the other.
	LessThanOrEqual	The less than or equal relation operator (<=) compares its operands to determine which one is less than or equal to the other.

Remarks

The PIPointClass represents a template of attributes used for creating a PIPoint. Each PIPoint on a PIServer refers to a single PIPointClass that defines the attributes that apply to the PIPoint.

Notes to Callers
This method, property, or class is not available in the legacy .NET 3.5 version of the SDK.

Examples

// Get the PIPointClasses from the PIServer on the local computer
PISystems myPISystems = new PISystems();
PISystem myPISystem = myPISystems.DefaultPISystem;
PIServer myPIServer = PIServer.FindPIServer(myPISystem, piServerName);


// Display information about each PIPointClass and its attributes
foreach (PIPointClass pointClass in myPIServer.PointClasses)
{
    Console.WriteLine("Name of the PIPointClass = {0}", pointClass.Name);
    IDictionary<string, object> attributes = pointClass.GetAttributes();
    foreach (var item in attributes)
    {
        Console.WriteLine("  Attribute '{0}' = '{1}'", item.Key, item.Value);
    }
}

' Get the PIPointClasses from the PIServer on the local computer
Dim myPISystems As New PISystems
Dim myPISystem As PISystem = myPISystems.DefaultPISystem
Dim myPIServer As PIServer = PIServer.FindPIServer(myPISystem, piServerName)

' Display information about each PIPointClass and its attributes
For Each pointClass As PIPointClass In myPIServer.PointClasses
    Console.WriteLine("Name of the PIPointClass = {0}", pointClass.Name)
    Dim attributes As IDictionary(Of String, Object) = pointClass.GetAttributes
    For Each item As KeyValuePair(Of String, Object) In attributes
        Console.WriteLine("  Attribute '{0}' = '{1}'", item.Key, item.Value)
    Next
Next
