public interface VectorAccessible extends Iterable<VectorWrapper<?>>

  • Method Details

    • 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()
