Constructor Details

WindowDataBatch

public WindowDataBatch(VectorAccessible batch,
 OperatorContext oContext)

Method Details

getContext

public OperatorContext getContext()

getContainer

public VectorContainer getContainer()

getRecordCount

public int getRecordCount()

Description copied from interface: VectorAccessible

Get the number of records.

Specified by:

getRecordCount in interface VectorAccessible

Returns:

number of records

getValueAccessorById

public VectorWrapper<?> getValueAccessorById(Class<?> clazz,
 int... fieldIds)

Specified by:

getValueAccessorById in interface VectorAccessible

getValueVectorId

public TypedFieldId getValueVectorId(SchemaPath path)

Description copied from interface: VectorAccessible

Get the value vector type and id for the given schema path. The TypedFieldId should store a fieldId which is the same as the ordinal position of the field within the Iterator provided this classes implementation of Iterable<ValueVector>.

Specified by:

getValueVectorId in interface VectorAccessible

Parameters:

path - the path where the vector should be located.

Returns:

the local field id associated with this vector. If no field matches this path, this will return a null TypedFieldId

getSchema

public BatchSchema getSchema()

Description copied from interface: VectorAccessible

Get the schema of the current RecordBatch. This changes if and only if a *_NEW_SCHEMA IterOutcome is provided.

Specified by:

getSchema in interface VectorAccessible

Returns:

schema of the current batch

iterator

public Iterator<VectorWrapper<?>> iterator()

Specified by:

iterator in interface Iterable<VectorWrapper<?>>

getSelectionVector2

public SelectionVector2 getSelectionVector2()

Specified by:

getSelectionVector2 in interface VectorAccessible

getSelectionVector4

public SelectionVector4 getSelectionVector4()

Specified by:

getSelectionVector4 in interface VectorAccessible

clear

public void clear()

toString

public String toString()

Overrides:

toString in class Object
