Enumeration Type Documentation

enum Apama.Services.Scenario.DiscoveryStatus

An enumeration to represent the discovery status within the Scenario Service.

The possible String value of the states are "Pending", "Active" and "Complete".

The are three static instances of the class, one for each element in the enum.

• None indicates an invalid/unitialised state.
• Pending indicates that the discovery process has not yet started. Possible next states: Active.
• Active indicates that the discovery process has started but is not yet complete. Possible next states: Pending, Complete.
• Complete indicates that the discovery process is complete. Possible next states: Pending.

Enumerator
None	None indicates an invalid/unitialised state.
Pending	Pending indicates that the discovery process has not yet started.
Active	Active indicates that the discovery process has started but is not yet complete.
Complete	Complete indicates that the discovery process is complete.

enum Apama.Services.Scenario.InstanceState

Enum to handle the StateChange event.

The valid states are Running, Ended and Failed.

• Running is the default state when an Instance is created.
• Ended when the instance reaches the END.
• Failed when the instance died unexpectedly.

Enumerator
Running	The default state when an Instance is created.
Ended	The state when the instance reaches the END.
Failed	The state when the instance died unexpectedly.

enum Apama.Services.Scenario.ParameterType

An enumeration that models the "type" of scenario input/output parameters.

For extension and helper methods for this type, see Apama.Services.Scenario.ParameterTypeHelper.

There are several type structures used when dealing with scenarios: .NET types, MonitorScript types, and a kind of extension to MonitorScript types that are used within ScenarioManager to add support for enumerations. The point of this enumeration is to ease the development of code that must deal with these types and conversions between them. Note that the Scenario enumeration type is modelled as a string in MonitorScript, and a System.String in .NET.

The following table shows the relationship between these type systems.

ScenarioManager GUI	Scenario Type	MonitorScript Type	.NET Type	Java Type
Text	string	string	System.String	java.lang.String
Whole Number	integer	integer	System.Int64	java.lang.Long
Number	float	float	System.Double	java.lang.Double
?	decimal	decimal	DecimalFieldValue	DecimalFieldValue
True/False	boolean	boolean	System.Boolean	java.lang.Boolean
Choice	enumeration	string	System.String	java.lang.String

Enumerator
None	(deprecated) None Type Deprecated - None is not a supported type for scenario variables, and this enumeration member may be removed in a future release. Please do not use.
Boolean	Boolean Type
Enumeration	Enumeration Type
Float	Float Type
Decimal	Decimal Type
Integer	Integer Type
String	String Type

enum Apama.Services.Scenario.ScenarioType

An enumeration that models the "type" of scenario.

There are several scenario types: ordinary Scenarios, DataViews and Queries. The point of this enumeration is to ease the distinction between them. Unkown is used for types that cannot be resolved or is none of the above.
