SUBREADER
public static final FieldCacheSanityChecker.InsanityType SUBREADER
Indicates an overlap in cache usage on a given field in sub/super readers.
-
VALUEMISMATCH
public static final FieldCacheSanityChecker.InsanityType VALUEMISMATCH
Indicates entries have the same reader+fieldname but different cached values. This can happen if different datatypes, or parsers are used -- and while it's not necessarily a bug it's typically an indication of a possible problem.
NOTE: Only the reader, fieldname, and cached value are actually tested -- if two cache entries have different parsers or datatypes but the cached values are the same Object (== not just equal()) this method does not consider that a red flag. This allows for subtle variations in the way a Parser is specified (null vs DEFAULT_LONG_PARSER, etc...)
-
EXPECTED
public static final FieldCacheSanityChecker.InsanityType EXPECTED
Indicates an expected bit of "insanity". This may be useful for clients that wish to preserve/log information about insane usage but indicate that it was expected.
