The Distribution type exposes the following members.

Constructors

	Name	Description
	Distribution	Called from constructors in derived classes to initialize the Distribution class.

Top

Properties

	Name	Description
	ExtensionHandle	Gets the extension handle for the associated object.

Methods

	Name	Description
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetRangeValue	Returns a value between 0 and 1 that represents a point on the distribution curve.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Initialize	Initializes this instance by using the provided initialization information.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnGetRangeValue	Returns a value between 0 and 1 and represents a point on the distribution curve.
	OnInitialize	Initializes a distribution when it is overridden in a derived class.
	OnSetInputValues	Implements custom behavior that is executed when the input values for a distribution are set.
	OnValidateInputs	Validates that all the required input properties for the distribution have been set when they are overridden in a derived class.
	SetExtensionHandle	Sets the extension handle.
	SetInputValues	Sets input values for a distribution. This method cannot be overridden.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	ValidateInputs	Validates that all the required input properties for the distribution have been set.

Remarks

Each numeric data generator has a Distribution property. The user can specify that the property generates data that approximates a statistical distribution curve. The standard distribution options are as follows: Uniform, Normal, Normal Inverse, Exponential, and Exponential Inverse.

If the standard distributions are insufficient, you can create a custom distribution. To create a custom distribution, you must create a class that implements IDistribution or inherits from Distribution. You identify the class as a distribution by decorating it with DistributionAttribute.

You can create a custom designer for a custom distribution to work with the object at design time, or you can use the DefaultDistributionDesigner.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
