Interface Summary

Interface	Description
FixedWidthVector
NullableVector
NullableVector.Mutator
NullableVectorDefinitionSetter
UntypedReader
ValueVector	An abstraction that is used to store a sequence of values in an individual column.
ValueVector.Accessor	Reads from this vector instance.
ValueVector.Mutator	Writes into this vector instance.
VariableWidthVector
VariableWidthVector.VariableWidthAccessor
VariableWidthVector.VariableWidthMutator
VarLenBulkEntry	A bulk input entry enables us to process potentially multiple VL values in one shot (especially for very small values); please refer to org.apache.drill.exec.vector.VarBinaryVector.BulkInput.
VarLenBulkInput<T extends VarLenBulkEntry>	Allows caller to provide input in a bulk manner while abstracting the underlying data structure to provide performance optimizations opportunities.
VarLenBulkInput.BulkInputCallback<T extends VarLenBulkEntry>	Enables caller (such as wrapper vector objects) to include more processing logic as the data is being streamed.
