Syntax

struct FPersistentEvaluationData

Remarks

Structure that stores persistent data that track templates may need during evaluation. Such data can be thought of as a cache which exists as long as the track is being evaluated. The cache can store any abstract data provided it implements IPersistentEvaluationData. Data is stored in buckets that is keyed on either the track (ie, accessible from all child templates/sections), or section (only accessible within the section) Type-safety (through the templated methods) is the responsibility of the user. There should only ever be 1 type of data for each section/track association.
