Constructor and Description |
---|
SmallIntVector(String name,
BufferAllocator allocator)
Instantiate a SmallIntVector.
|
SmallIntVector(String name,
FieldType fieldType,
BufferAllocator allocator)
Instantiate a SmallIntVector.
|
Modifier and Type | Method and Description |
---|---|
void |
copyFrom(int fromIndex,
int thisIndex,
SmallIntVector from)
Copy a cell value from a particular index in source vector to a particular
position in this vector
|
void |
copyFromSafe(int fromIndex,
int thisIndex,
SmallIntVector from)
Same as
copyFrom(int, int, SmallIntVector) except that
it handles the case when the capacity of the vector needs to be expanded
before copy. |
static short |
get(ArrowBuf buffer,
int index)
Given a data buffer, get the value stored at a particular position
in the vector.
|
short |
get(int index)
Get the element at the given index from the vector.
|
void |
get(int index,
NullableSmallIntHolder holder)
Get the element at the given index from the vector and
sets the state in holder.
|
Types.MinorType |
getMinorType()
Get minor type for this vector.
|
Short |
getObject(int index)
Same as
get(int) . |
FieldReader |
getReader()
Get a reader that supports reading values from this vector
|
TransferPair |
getTransferPair(String ref,
BufferAllocator allocator)
Construct a TransferPair comprising of this and and a target vector of
the same type.
|
TransferPair |
makeTransferPair(ValueVector to)
Construct a TransferPair with a desired target vector of the same type.
|
void |
set(int index,
int value)
Set the element at the given index to the given value.
|
void |
set(int index,
int isSet,
short value)
Store the given value at a particular position in the vector. isSet indicates
whether the value is NULL or not.
|
void |
set(int index,
NullableSmallIntHolder holder)
Set the element at the given index to the value set in data holder.
|
void |
set(int index,
short value)
Set the element at the given index to the given value.
|
void |
set(int index,
SmallIntHolder holder)
Set the element at the given index to the value set in data holder.
|
void |
setNull(int index)
Set the element at the given index to null.
|
void |
setSafe(int index,
int value)
Same as
set(int, int) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |
void |
setSafe(int index,
int isSet,
short value)
Same as
set(int, int, short) except that it handles the case
when index is greater than or equal to current value capacity of the
vector. |
void |
setSafe(int index,
NullableSmallIntHolder holder)
Same as
set(int, NullableSmallIntHolder) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |
void |
setSafe(int index,
short value)
Same as
set(int, short) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |
void |
setSafe(int index,
SmallIntHolder holder)
Same as
set(int, SmallIntHolder) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |
