IParameterCollection Interface#

Represents a collection of parameters that are identified by a path, a name, and a type.

Syntax#

C#


public interface IParameterCollection : IEnumerable<IParameter>

VB


Public Interface IParameterCollection
    Inherits IEnumerable(Of IParameter)

The IParameterCollection type exposes the following members.

Properties#

	Name	Description
	Item(ArrayName)	Looks up a parameter of type array and returns it. If no parameter with the given name has been found, an empty parameter is returned to simplify handling.
	Item(BooleanName)	Looks up a parameter of type boolean and returns it. If no parameter with the given name has been found, an empty parameter is returned to simplify handling.
	Item(CommandName)	Looks up a parameter of type command and returns it. If no parameter with the given name has been found, an empty parameter is returned to simplify handling.
	Item(EnumName)	Looks up a parameter of type enum and returns it. If no parameter with the given name has been found, an empty parameter is returned to simplify handling.
	Item(FloatName)	Looks up a parameter of type float and returns it. If no parameter with the given name has been found, an empty parameter is returned to simplify handling.
	Item(IntegerName)	Looks up a parameter of type integer and returns it. If no parameter with the given name has been found, an empty parameter is returned to simplify handling.
	Item(String)	Looks up a parameter of any type and returns it. If no parameter with the given name has been found, an empty parameter is returned to simplify handling.
	Item(StringName)	Looks up a parameter of type string and returns it. If no parameter with the given name has been found, an empty parameter is returned to simplify handling.

	GetParameterRelation	Advanced: Gets the relation of one parameter to other parameters.
	Load	Loads the parameters from a file.
	Poll	Advanced: Poll all parameters that have polling time. If the elapsed time is larger than the polling time of the parameter, fire parameter changed events.
	Refresh	Advanced: Invalidates all cached values for all parameters. See Refresh() for more information.
	Save	Saves the parameters to a file.

Remarks#

Every parameter collection has a main parameter path. When looking up parameters of the main path, the path can be omitted. The definition of a main parameter path depends on the source of the related parameter collection. For simplicity, a combination of path, name, and type is referred to as parameter name, analogous to file names.

Examples:

Parameter name without path: "Width"
Parameter name with path: "@CameraDevice/Width"
Parameter name with name cast for defining the parameter type: (IntegerName) "@CameraDevice/Width"

For ease of use, several predefined lists of parameter names are available, e.g. PLCamera.

If a requested parameter does not exist, an empty parameter object will be returned to simplify handling. An empty parameter is never readable or writable.

A parameter collection is enumerable. The enumerator lists all user parameters.
