public static LazyPrimitive<? extends ObjectInspector,? extends Writable> createLazyPrimitiveClass(PrimitiveObjectInspector poi, boolean typeBinary)
poi
- PrimitiveObjectInspectortypeBinary
- a switch to return either a LazyPrimtive class or it's binary
companion

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
public static ObjectInspector createLazyStructInspector(List<String> columnNames, List<TypeInfo> typeInfos, byte[] separators, Text nullSequence, boolean lastColumnTakesRest, boolean escaped, byte escapeChar) throws SerDeException
lastColumnTakesRest
- whether the last column of the struct should take the rest of the
row if there are extra fields.
