Specified by:

getValueVector in interface VectorWrapper<T extends ValueVector>

getValueVectors

public T[] getValueVectors()

Specified by:

getValueVectors in interface VectorWrapper<T extends ValueVector>

isHyper

public boolean isHyper()

Specified by:

isHyper in interface VectorWrapper<T extends ValueVector>

clear

public void clear()

Specified by:

clear in interface VectorWrapper<T extends ValueVector>

getChildWrapper

public VectorWrapper<?> getChildWrapper(int[] ids)

Specified by:

getChildWrapper in interface VectorWrapper<T extends ValueVector>

getFieldIdIfMatches

public TypedFieldId getFieldIdIfMatches(int id,
                                        SchemaPath expectedPath)

Description copied from interface: VectorWrapper

Traverse the object graph and determine whether the provided SchemaPath matches data within the Wrapper. If so, return a TypedFieldId associated with this path.

Specified by:

getFieldIdIfMatches in interface VectorWrapper<T extends ValueVector>

Returns:

TypedFieldId

cloneAndTransfer

public VectorWrapper<T> cloneAndTransfer(BufferAllocator allocator)

Specified by:

cloneAndTransfer in interface VectorWrapper<T extends ValueVector>

create

public static <T extends ValueVector> HyperVectorWrapper<T> create(MaterializedField f,
                                                                   T[] v,

addVector

public void addVector(ValueVector v)

addVectors

public void addVectors(ValueVector[] vv)

transfer

public void transfer(VectorWrapper<?> destination)

Transfer vectors to destination HyperVectorWrapper. Both this and destination must be of same type and have same number of vectors.

destination - destination HyperVectorWrapper.

updateVectorList

public void updateVectorList(ValueVector[] vv)

Method to replace existing list of vectors with the newly provided ValueVectors list in this HyperVectorWrapper

Parameters:

vv - - New list of ValueVectors to be stored
