Syntax
public sealed class PIPointSource : IComparable, IComparable<PIPointSource>, IEquatable<PIPointSource>
Public NotInheritable Class PIPointSource Implements IComparable, IComparable(Of PIPointSource), IEquatable(Of PIPointSource) Dim instance As PIPointSource

[<SealedAttribute>] type PIPointSource = class interface IComparable interface IComparable<PIPointSource> interface IEquatable<PIPointSource> end
The PIPointSource type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
 | Description |
This property identifies the Description of the PIPointSource.
|
| Name |
This property identifies the name of the PIPointSource.
|
| PointCount |
The point count associated with the PIPointSource.
|
| Server |
The PIServer for this PIPointSource.
|
Methods
| Name | Description | |
|---|---|---|
 | CompareTo(Object) |
Compares this instance with a specified Object.
|
| CompareTo(PIPointSource) |
Compares this instance with a specified PIPointSource.
|
| Equals(Object) |
Determines whether the specified Object is equal to the current object.
(Overrides ObjectEquals(Object).) |
| Equals(PIPointSource) |
Indicates whether the current object is equal to another object of the same type.
|
| 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 PIPointSource represents a
PointSource Attribute associated with
a PIPoint. Each PIPoint belongs to a specific
PIPointSource on a PIServer. The total number of points associated
with the point source is available in the PointCount property.
