RepeatedDictVector

public RepeatedDictVector(MaterializedField field,
 BufferAllocator allocator,
 CallBack callback)

Method Details

allocateNew

public void allocateNew()
                 throws OutOfMemoryException

Description copied from interface: ValueVector

Allocate new buffers. ValueVector implements logic to determine how much to allocate.

Throws:

OutOfMemoryException - Thrown if no memory can be allocated.

getTransferPair

public TransferPair getTransferPair(String ref,
 BufferAllocator allocator)

makeTransferPair

public TransferPair makeTransferPair(ValueVector target)

Description copied from interface: ValueVector

Returns a new transfer pair that is used to transfer underlying buffers into the target vector.

getField

public MaterializedField getField()

Description copied from interface: ValueVector

Get information about how this field is materialized.

Specified by:

getField in interface ValueVector

Overrides:

getField in class BaseValueVector

getAccessor

public RepeatedDictVector.Accessor getAccessor()

Description copied from interface: ValueVector

Returns an accessor that is used to read from this vector instance.

getMutator

public RepeatedDictVector.Mutator getMutator()

Description copied from interface: ValueVector

Returns an mutator that is used to write to this vector instance.

getReader

public FieldReader getReader()

Description copied from interface: ValueVector

Returns a field reader that supports reading values from this vector.

copyEntry

public void copyEntry(int toIndex,
 ValueVector from,
 int fromIndex)
