Member Function Documentation

getCacheableMetadata ( )

{Gets the cacheability metadata for the context.There are three valid cases for the returned CacheableMetadata object:

  • An empty object means this can be optimized away safely.
  • A max-age of 0 means that this context can never be optimized away. It will never bubble up and cache tags will not be used.
  • Any non-zero max-age and cache tags will bubble up into the cache item if this is optimized away to allow for invalidation if the context value changes.
Returns
A cacheable metadata object.
