Method Detail

getValueAccessorById

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

getValueVectorId

TypedFieldId getValueVectorId(SchemaPath path)

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>.

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

BatchSchema getSchema()

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

Returns:

schema of the current batch

getRecordCount

int getRecordCount()

Get the number of records.

Returns:

number of records

getSelectionVector2

SelectionVector2 getSelectionVector2()

getSelectionVector4

SelectionVector4 getSelectionVector4()
