public final class TimeStampMicroTZVector
extends TimeStampVector

TimeStampMicroTZVector implements a fixed width vector (8 bytes) of timestamp (microsecond resolution) values which could be null. A validity buffer (bit vector) is maintained to track which elements in the vector are null.

Constructor Details

TimeStampMicroTZVector

public TimeStampMicroTZVector(String name,
 BufferAllocator allocator,
 String timeZone)

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

Parameters:

name - name of the vector

allocator - allocator for memory management.

TimeStampMicroTZVector

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

Instantiate a TimeStampMicroTZVector. 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.

TimeStampMicroTZVector

public TimeStampMicroTZVector(Field field,
 BufferAllocator allocator)

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

Parameters:

field - Field materialized by this vector

allocator - allocator for memory management.

Method Details

getReaderImpl

protected FieldReader getReaderImpl()

Description copied from class: BaseValueVector

Each vector has a different reader that implements the FieldReader interface. Overridden methods must make sure to return the correct concrete reader implementation.

Specified by:

getReaderImpl in class BaseValueVector

Returns:

Returns a lambda that initializes a reader when called.

getMinorType

public Types.MinorType getMinorType()

Get minor type for this vector. The vector holds values belonging to a particular type.

Returns:

Types.MinorType

getTimeZone

public String getTimeZone()

Get the time zone of the timestamps stored in this vector.

Returns:

the time zone of the timestamps stored in this vector.

get

public void get(int index,
 NullableTimeStampMicroTZHolder holder)

Get the element at the given index from the vector and sets the state in holder. If element at given index is null, holder.isSet will be zero.

Parameters:

index - position of element

getObject

public Long getObject(int index)

Same as TimeStampVector.get(int).

Parameters:

index - position of element

Returns:

element at given index

set

public void set(int index,
 NullableTimeStampMicroTZHolder holder)
         throws IllegalArgumentException

Set the element at the given index to the value set in data holder. If the value in holder is not indicated as set, element in the at the given index will be null.

Parameters:

index - position of element

holder - nullable data holder for value of element

Throws:

IllegalArgumentException

set

public void set(int index,
 TimeStampMicroTZHolder holder)

Set the element at the given index to the value set in data holder.

Parameters:

index - position of element

holder - data holder for value of element

setSafe

public void setSafe(int index,
 NullableTimeStampMicroTZHolder holder)
             throws IllegalArgumentException

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

Parameters:

index - position of element

holder - nullable data holder for value of element

Throws:

IllegalArgumentException

setSafe

public void setSafe(int index,
 TimeStampMicroTZHolder holder)

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

Parameters:

index - position of element

holder - data holder for value of element

getTransferPair

public TransferPair getTransferPair(String ref,
 BufferAllocator allocator)

Construct a TransferPair comprising this and a target vector of the same type.

Specified by:

getTransferPair in interface ValueVector

Specified by:

getTransferPair in class BaseFixedWidthVector

Parameters:

ref - name of the target vector

allocator - allocator for the target vector

Returns:

TransferPair

getTransferPair

public TransferPair getTransferPair(Field field,
 BufferAllocator allocator)

Construct a TransferPair comprising this and a target vector of the same type.

Specified by:

getTransferPair in interface ValueVector

Specified by:

getTransferPair in class BaseFixedWidthVector

Parameters:

field - Field object used by the target vector

allocator - allocator for the target vector

Returns:

TransferPair

makeTransferPair

public TransferPair makeTransferPair(ValueVector to)

Construct a TransferPair with a desired target vector of the same type.

Parameters:

to - target vector

Returns:

TransferPair
