Detailed Description

Thresholds to tune inline cost analysis.

The inline cost analysis decides the condition to apply a threshold and applies it. Otherwise, DefaultThreshold is used. If a threshold is Optional, it is applied only when it has a valid value. Typically, users of inline cost analysis obtain an InlineParams object through one of the getInlineParams methods and pass it to getInlineCost. Some specialized versions of inliner (such as the pre-inliner) might have custom logic to compute InlineParams object.
