typeBinary
is specified as true.oi
- ObjectInspectortypeBinary
- Boolean value used as switch to return variants of LazyPrimitive
objects which are initialized from a binary format for the data.public static ObjectInspector createLazyObjectInspector(TypeInfo typeInfo, byte[] separator, int separatorIndex, Text nullSequence, boolean escaped, byte escapeChar) throws SerDeException
typeInfo
- The type information for the LazyObjectseparator
- The array of separators for delimiting each levelseparatorIndex
- The current level (for separators). List(array), struct uses 1
level of separator, and map uses 2 levels: the first one for
delimiting entries, the second one for delimiting key and values.nullSequence
- The sequence of bytes representing NULL.SerDeException

lastColumnTakesRest
- whether the last column of the struct should take the rest of the
row if there are extra fields.SerDeException
