BatchGroup

public BatchGroup(VectorContainer container,
          SelectionVector2 sv2,
          OperatorContext context)

BatchGroup

public BatchGroup(VectorContainer container,
          org.apache.hadoop.fs.FileSystem fs,
          String path,
          OperatorContext context)

Method Detail

getSv2

public SelectionVector2 getSv2()

setSchema

public void setSchema(BatchSchema schema)

Updates the schema for this batch group. The current as well as any deserialized batches will be coerced to this schema

Parameters:

schema -

addBatch

public void addBatch(VectorContainer newContainer)
              throws IOException

Throws:

IOException

getNextIndex

public int getNextIndex()

getContainer

public VectorContainer getContainer()

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Throws:

IOException

closeOutputStream

public void closeOutputStream()
                       throws IOException

Throws:

IOException

getValueAccessorById

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

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.

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

getRecordCount

public int getRecordCount()

Description copied from interface: VectorAccessible

Get the number of records.

Specified by:

getRecordCount in interface VectorAccessible

Returns:

number of records

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
