public abstract class TimeStampVector
extends BaseFixedWidthVector

TimeStampVector is an abstract interface for fixed width vector (8 bytes) of timestamp values which could be null. A validity buffer (bit vector) is maintained to track which elements in the vector are null.

Constructor Detail

TimeStampVector

public TimeStampVector(String name,
                       FieldType fieldType,
                       BufferAllocator allocator)

Instantiate a TimeStampVector. This doesn't allocate any memory for the data in vector.

Parameters:

name - name of the vector

fieldType - type of Field materialized by this vector

allocator - allocator for memory management.

TimeStampVector

public TimeStampVector(Field field,
                       BufferAllocator allocator)

Instantiate a TimeStampVector. This doesn't allocate any memory for the data in vector.

Parameters:

field - field materialized by this vector

allocator - allocator for memory management.

Method Detail

get

public long get(int index)
         throws IllegalStateException

Get the element at the given index from the vector.

Parameters:

index - position of element

Returns:

element at given index

Throws:

IllegalStateException

setValue

protected void setValue(int index,
                        long value)

set

public void set(int index,
                long value)

Set the element at the given index to the given value.

Parameters:

index - position of element

value - value of element

setSafe

public void setSafe(int index,
                    long value)

Same as set(int, long) except that it handles the case when index is greater than or equal to existing value capacity BaseFixedWidthVector.getValueCapacity().

Parameters:

index - position of element

value - value of element

set

public void set(int index,
                int isSet,
                long value)

Store the given value at a particular position in the vector. isSet indicates whether the value is NULL or not.

Parameters:

index - position of the new value

isSet - 0 for NULL value, 1 otherwise

value - element value

setSafe

public void setSafe(int index,
                    int isSet,
                    long value)

Same as set(int, int, long) except that it handles the case when index is greater than or equal to current value capacity of the vector.

Parameters:

index - position of the new value

isSet - 0 for NULL value, 1 otherwise

value - element value

get

public static long get(ArrowBuf buffer,
                       int index)

Given a data buffer, get the value stored at a particular position in the vector.

This method should not be used externally.

Parameters:

buffer - data buffer

index - position of the element.

Returns:

value stored at the index.
