Description

Interval list containing intervals during which specified condition is satisfied. Determination is performed within interval list using Sampling and Convergence parameters.

Object Model

Public Properties

Condition	The condition component.
Convergence	The Convergence definition, which uses time tolerance to determine when times for intervals of satisfaction are found.
CustomTimeLimits	The interval list or single interval within which intervals of satisfaction are sought. The specified value is used if UseCustomTimeLimits is true. The default is set to overall availability of host object. The time limits will be used if UseCustomTimeLimits is set to true.
Sampling	The Sampling definition, which can use a fixed step, relative tolerance or curvature tolerance. Relative tolerance uses a combination of relative and absolute changes in scalar values between samples. Curvature tolerance also uses changes in slope between samples.
SaveDataOption	Determine if computed intervals of satisfaction are saved/loaded, or recomputed on load if necessary.
UseCustomTimeLimits	Indicate whether to use specified custom time limits (see CustomTimeLimits).

Example

Create and configure list condition event interval.
