public class ExtensionItemFilterProcessor
extends ItemValueFilterProcessor<ValueFilter<?,?>>

Filter processor for extension items stored in JSONB. This takes care of any supported type, scalar or array, and handles any operation. NOTE about NOT treatment: We use the same not treatment for extensions like for other columns resulting in conditions like: `not (u.ext->>'1510' < ? and u.ext->>'1510' is not null)` One might think that the part after AND can be replaced with u.ext ? '1510' to benefit from the GIN index. But `NOT (u.ext ? '...')` is *not* fully complement to the `u.ext ? '...'` (without NOT). It is only fully complement if additional `AND u.ext is not null` is added in which case the index will not be used either. So instead of adding special treatment code for extensions, we just reuse existing predicateWithNotTreated methods.

isIgnoreCaseFilter

protected boolean isIgnoreCaseFilter(ValueFilter<?,?> filter)

Description copied from class: ItemValueFilterProcessor

Returns true, if the filter implies ignore-case behavior. Used when filter is transformed to SQL operation, or to determine whether operands need some treatment (e.g. `lower()` function). Can be overridden to cover other matching rules, e.g. for poly-strings.

Overrides:

isIgnoreCaseFilter in class ItemValueFilterProcessor<ValueFilter<?,?>>
